What is a Leaky Feeder Cable?

A leaky feeder is an electrical cable that transmits and delivers electricity. This cable allows liquid to lubricate inner conductors and prevents electrolysis corrosion. Leaky feeders can be used in applications where it is impossible or impractical for them to remain dry. Here we explain what a leaky feeder cable is exactly.

There are many types of cables that can transmit electricity. An electrician or an electrical engineer must make the right choice when choosing the best type of cable to transmit electricity.

Let’s say you want to install a high-definition TV in your living room. You may choose to use speaker wire to connect your TV. It is available in lengths of up to 100 feet, and has two copper conductors within each jacketed sheath. You will need to use 24 gauge wire to get 720p resolution.

This wire is not thick enough to be a 2-conductor-cable. This same-sized cable is also not suitable for carrying current to certain devices such as speakers or electric drills.

Wiring that is extra-heavy-duty requires a cable with four copper conductors in each jacketed sheath. This cable is often used in large industrial settings such as hospitals and large factories that use many types of current-carrying equipment.

A thinner jacket is used to prevent a leaky feeder cable from being tampered with by code. To make the cable waterproof, a special coating is applied inside. It becomes saturated with water and an electric charge forms between the copper conductors.

Varis Smartcom(r.150IS) Leaky Feeder Cables are ideal for anyone who needs to provide power to an AV device. With its durability and quality, this cable will be a reliable companion. This cable is ideal for people who don’t want cables to break while they are in use, or anyone who is always on the move!

The radio signals from Head End, which are usually located at the surface, are transmitted underground via the leaky feeder cables. The signal can also be easily retransmitted on the surface and can cover several kilometers.


Coaxial cable was designed to retain as much signal as possible and block external signals. Leaky Feeder cables are designed to leak or radiate radio signals out and allow signals in from remote radio transceivers located within 50-200 meters of the Leaky Feeder Cable. Line Amplifiers or boosters are installed along with the Leaky feeder cable runs, nominally every 350m. They help sustain signal levels over long distances.


Certified Becker communication engineers design leaky feeder systems in consultation with customers and meet all compliance requirements.


As a mine grows, leaky Feeder cables will need to be repaired and extended. It is important to make quick connections and repairs in order to minimize downtime and ensure reliable operations. These requirements can be met by the Becker splice device. Line splices are used to join two sections together, where signal amplification does not apply, or to repair damaged sections. To properly terminate the system, line terminations are placed at the Leaky Feeder cables.

Wireless Radio Networks Save Miners Every Day

Leaky Feeder Communication

The most advanced solution for mining communications was until recently, a leaky feeder. Leaky feeders can transmit wireless radio network frequencies that save miners! They are similar to coaxial cables, which transmit a signal from one point to the next. Coaxial cables are usually protected by a copper sheath around the cable to stop the signal from leaking throughout its length. You might not be capable of detecting signals with a radio from the other endpoint if the network has a long cable, unlike a wireless radio network.

Leaky feeders can be very different. Leaky feeders have small gaps in their shielding that allow the signal to pass instead of being covered with a copper shield. These gaps create a restricted wireless radio network environment. To compensate for the loss of signal, line amplifiers and repeaters increase the signal at regular intervals on the cable. Leaky feeders can be interfaced with wireless devices. They can transmit and receive radio signals over the cable. Data can include voice, video, and computer data. You can control stationary equipment such as water pumps with radio receivers by using signals from the leaky feeder for a wireless radio network. To receive and transmit signals, you must still be within 300 feet (91.4m) of the cable.

A leaky feeder cable has one advantage: it can be laid down while you excavate a mine. Splitters can be used to send different lengths of cable along different routes. Flexible cable makes it easy to move the network around corners and curves. If necessary, you can feed cable directly down a hole. Leaky feeder systems have a few downsides. Communications will stop if the cable is cut. Multiple leaky feeder cables can cause interference in the system. Leaky feeder radio frequencies are more common in the high-end spectrum. These frequencies can’t penetrate rock very well.

Four leaky feeder systems have been approved by the Mine Safety and Health Administration (MSHA), which is the US government agency responsible for overseeing safety concerns in miner safety.

Mesh Networks

Mesh networks can be used in place of leaky feeders. A mesh network does not require a cable as a leaky feeder system. Let’s look closer at how wireless mesh networks can make mining safer. A mesh network transmits a wireless signal using a system called nodes. A node is basically a wireless router. The node is equipped with special software that allows it to communicate and collaborate with other nodes. Dynamic routing is used by the nodes to determine the best route for data transfers. The node location, data traffic, and other environmental factors can all influence the best route. Some nodes are mobile, most importantly.


A minimum of one node must be in a fixed location. This node acts as a bridge between the mesh and larger networks like the Internet. A radio tower connected to the Internet could serve as the main fixed point for a mine. Multiple fixed nodes are a common feature in mines to provide a strong foundation for the mesh network. Wireless mesh networks operate on one of two wireless radio network frequencies, 2.4 gigahertz for the IEEE 802.11 protocol or 900 megahertz for the IEEE 802.15 protocol. Both have issues broadcasting signals around corners so it may be necessary for the network to have a node at every corner. These protocols did not interfere with any other communication systems in mines, according to the MSHA.

The nodes do not have to be large. Many are approximately the same size as a typical wireless router. This makes it simple for miners to attach nodes on heavy equipment. Nodes can be used even when in motion, but at a slower bit speed. This means that many mining vehicles can transport the nodes. To monitor the mine conditions, you can also wire nodes to sensors. The node can transmit signals to the rest of the network if danger is averted. You can also build electronic badges that communicate with the mesh network. This allows the network to track individual miners’ locations. Different nodes will detect the badge of the miner as the miner moves through it. The mining company can determine if a section of the mine is hazardous and then evacuate it. To communicate with the surface, miners can use personal radios and voice-over-Internet protocol ( VOIP) phones.

While mesh networks can be used to prevent accidents, what happens if a part of the tunnel collapses? Unfortunately, mesh networks’ wireless protocols aren’t very efficient at reaching the earth. You need a system that works on extremely low frequencies to achieve this. A through-the-earth system (TTE), was tested by the Mine Safety and Health Administration (MSHA). It could penetrate rock up to 270 feet (82.3 meters). Data transfer was slow at 20-30 characters per minute, with an accuracy of 80 percent at depths up to 630 feet (192 meters). A TTE system could be capable of broadcasting further through solid ground. The downside is the slow data transfer speed. However, the MSHA discovered that TTE systems can interfere with other communication systems in mines.

To get back to the surface, miners use a wireless radio network. A reliable communication network can make the difference between life or death, considering how hazardous their job is. Contact us today for more information!



Radio Communication in Tunnels

Radio Communication in Tunnels

What is Radio Communication in Tunnels? Radio communication in tunnels is an adaptation of electronic communications made into a manual one. This allows people to communicate by using a radio device attached to their bodies, such as a cell phone or walkie-talkie, while in the tunnel. Radio communication can be used by tunnel workers to ensure safety and still have conversations that are not possible over regular voice radios. Radio communication can also be used to help other constituents (such as emergency personnel and construction workers) reach the person using it for tunnel talk.

Why is radio communication in tunnels important?

Radio communication is essential for many reasons. Radio communication is important from a safety perspective. It can be used even when visibility drops because it is possible to communicate with other people using their sensors or eyes. Radios can be used to keep people on the right track when there is heavy traffic. The tunnel’s radio communication can provide security to workers and others who travel through it. Imagine, for example, that there is an emergency at the tunnel and that a different evacuation method is required. People can be notified via radio and directed to exit by following certain instructions.

How does radio communication in tunnels work?

Low-power transmitters are placed throughout the tunnel system to make radio communication possible in tunnels. Each transmitter broadcasts its signal within a certain range. The transmitters will be in close proximity to each other so people can reach them throughout the tunnel. Tunnel workers can communicate with one another via walkie-talkies and cell phones. Most tunnel workers carry a base station that allows them to stay in touch with the main tunnel system.

What is Radio Communication used by emergency personnel, tunnel workers, and residents?

Radio communication is used by many people for various reasons. It is used by emergency personnel to prevent mishaps or accidents from occurring in the tunnel during an emergency. It is used by tunnel workers to ensure safety while they work, even in low visibility. Tunnel residents can also use radio communication in tunnels. Tunnel residents may use radio communication to summon emergency services, as it is vital for safety and security. People who are less sensitive to being seen can easily reach them.

The Best Gas Monitoring System Available

Becker Communications offers the SMARTCOM 100 LEAKY FEEDER SYSTEM, which allows divers to communicate below the water. Two wireless devices are worn by divers, one on each of their helmets and one on their wrists. A handheld device can be used to communicate with them. The transmitter transmits signals to the receiver. These signals are then transmitted to each other and their surface personnel, allowing them to see what’s happening underwater. These systems can be used to extract oil, gas, or for many other types of industries.

Underground Mine Communications: A Brief History

admin Mining Communication
Underground Mine Communications: A Brief History

A reliable and efficient communication system is essential for creating a safe, productive, and efficient mine. The history of materials extraction technology dates back many centuries. However, the era of underground mine communications systems can be traced back to the last century.

Just as above ground, the invention of the telephone triggered the mining communication revolution. Prior to the invention of the telephone, mine shaft communication was primarily based on bells and whistle signaling systems. Mines started to use ruggedized telephones that were connected via cables strung through the mines in the early 20th Century. Although the phones were the same as the ones above ground, they were enclosed in cast iron housings to protect them from the extreme temperatures, humidity, dust, or corrosive environments that can be found in a mine. Most phone systems were either based on a magneto (crank-ringer) format. These systems are still widely used today. They use a party-line format with one telephone per section and additional phones at key locations above or below ground. These systems are easy to set up and maintain due to their hard-wired design. However, miners will often have to stop working in order to use them.

The introduction of hoist-rope and trolley-carrier-based communication systems was made possible by the increased automation of mining in the 20th century. These carrier current systems use electrical connections to drive electric haulage systems. Because they are piggy-back systems, both systems are simple to install and provide strong mechanical strength. They are dependent on carrier frequency.

Radio made underground mine communications possible. Nicola Tesla investigated the possibility of using extremely low frequency (ELF), and naturally occurring minerals in mine structures, as a means of TTE (through-the Earth) communication. In the 1940s, South African gold mines were home to the first successful TTE system. In-mine research of ultra-high frequency and very high-frequency communications (VHF/UHF), began in the 1970s. Wave propagation in mine environments is difficult because of the complex topography, dynamic nature of mining operations, and the elements of the mine structures. Radio signals behave differently underground than in above-ground mines.

The “leaky feeder” mining communication system is a hybrid system, which was developed in the 1970s. The system combines both wired and wireless communication to ensure robust and flexible communication even in difficult mine environments. The backbone of the system is the leaky feeder cable. This is a coaxial cable with sections of the outer shielding that are shaved off during manufacture to allow RF signals to “leak out” (or leak in). It functions as an antenna and provides a communication path for radio transmissions within the mine. A repeater is connected to a leaky feeder cable. This cable is then extended into the mine with line amplifiers and repeaters to compensate the signal loss. Mining communications technology has advanced just as much in the last century as mineral extraction technology. We now have wireless communication systems which allow people on the surface to communicate with equipment and people miles below them, increasing safety and efficiency, as well as safety.

Mining Safety Starts With Communication Devices

Mining Safety Starts With Communication Devices

Good communication devices will help you avoid accidents in the mining industry.

If you work in the mining industry, it’s your responsibility to stay safe and be aware of dangers. Good communication devices, such as radios or personal alert systems can help make this possible.

Security personnel in the mining industry use hand signals to communicate. A signal is a special movement that lets others know what’s going on. You can use special hand signals to help avoid accidents in your mining operation. For example, if you’re operating a transport vehicle, you might point your thumb to the right to let others know you’re turning right.

Some companies require miners who work underground to wear electronic communication devices called personal alert systems (PAS). These devices work like radio beepers and can send a signal to let workers know they need to head surface.

A radio is another device that will help keep miners safe. It’s dangerous when miners work underground, where it’s hard to see each other around equipment and buildings. Radio communications allow miners to stay in contact with the surface, which reduces the risk of underground accidents.

Communication devices help to avoid accidents in mining sites. Workers from above the ground or below the surface are susceptible to fragmentation of rock and rockfall, literally raining down on them from above or blast from below. This is why cave in protection systems, such as rock bolting and cage bolting, are needed. When the ground may collapse beneath you, having a communication device that automatically alerts your colleagues to that fact can help save your life.

Fortunately enough, the mining industry has dramatically improved its safety record over the last century. The use of mining communication devices and PAS systems has become more widespread over time. It has helped reduce hazards in mining operations.

Your company should also have an emergency medical plan for accidents and injuries. Another good safety practice is to train your employees on the safe use of the equipment and how to respond to emergencies. They must also know how to use communication devices such as beepers or personal alert systems.

If you’re ever in a situation where you think someone needs help, don’t hesitate to call for assistance. The person you’re calling may be unable to hear or understand what you’re saying due to hearing loss or impaired vision. However, by using a voice transmitter or telecommunicator, you can relay your message to others and they will call for help.

In most cases, a network of beeper devices is able to recognize an emergency situation without the need for an operator to press the button. For example, miners can go underground using their handheld beepers as they descend if a mine cave-in occurs. One person on the surface can also use this as an opportunity to contact others out on foot who can assist in the rescue effort.

Usually, the beeper signals are composed of a number of different tones that tell someone exactly where on a map your location is. The signal considers the surrounding noise, which makes it easier to locate you. Beepers are also useful in areas where there is no cell phone service. The beeper devices will then work as a distress signal or sign that indicates an emergency situation.

According to many statistics, 75% of an employee’s safety depends on communication between them and their supervisors (Ryan & Laughlin, 2009). Therefore, it is important that supervisors understand how to use communication devices (beepers) and PAS systems in the mining industry. The communication devices that can be used are portable or hands-free.

First and foremost, it is important for supervisors to know that they can always contact their employees using PAS systems or other communication devices such as beepers. It is also important to be aware of the consequences of not following safety guidelines when using communications devices such as beepers and personal alert systems.

The Benefits of a VHF Leaky Feeder System

Whenever we change something, there could be positive or negative effects associated with such an action. However, when you make changes to improve business processes or increase productivity, then these can have drastic effects on your organization’s overall performance. In this article, we will talk about the benefits of a VHF Leaky Feeder System.

One of the key areas of investment in any mining operation is the feeder systems. These are the systems that feed minerals into the mining equipment and can also be used for storing minerals and treating them before they are loaded into trucks for delivery to customers. Feeder systems can also help ensure that minerals found in a mine are properly treated. This is a crucial element to consider as it could impact production results.

Feeder systems are an important investment for any mining operation. The type of feeder system used can directly impact the overall performance of a mining operation. This is because of these systems’ innovative design and features, which means they have advanced control mechanisms that help increase productivity and efficiency.

As you would expect, with any investment in the mining industry, finding and implementing an effective feeder system requires extensive research. This is because the feeder system needs to be able to provide proper connectivity between the conveyor belt system, mineral storage, and recovery systems, and any other equipment used at the mine. To ensure that all of these systems are connected effectively, it is important to have a feeder system that uses a lightweight, highly durable, and efficient system.

There are many different types of systems available on the market today, but one of these that has become increasingly popular in recent years is a VHF leaky feeder system. This system has several advantages that make them an ideal choice for mining operations.

One of the main advantages associated with using a VHF leaky feeder system in any mining operation is that it prevents any signal leakage. This means that the signal from a high-frequency transmitter will only travel through the system and not around it or outside of it. To understand why this is important, you need to know how a VHF leaky feeder operates within a mining operation.

The VHF leaky feeder system is used to transmit the signal from a high-frequency transmitter located in the control room. The system will then transmit this signal to either a relay or breaker panel at the other end of the system. The signal is then switched on or off based on how far it has traveled and where it is going. The length of this system can be very long, but it will still never travel out of the area in which it was installed.

VHF leaky feeder systems also come with advanced features that make them an excellent choice for several different industries, and the mining industry is no exception. For example, they have been widely used in past years to provide extremely efficient transmission within the oil sector. As well as being able to transmit signals over long distances, this type of system is also capable of carrying a large amount of data in a short period of time.

In addition to this, the VHF leaky feeder system has several other advantages associated with its use. It is very easy to install, for starters, since it does not need to be buried in the ground. This means that you can easily install a comprehensive system in a short period of time without having to dig deep trenches around the area where the system is being installed.

You must find and implement an effective feeder system in your organization before you expect production to increase. This will help improve productivity and efficiency within your organization and ensure that the production targets you have set are met.

Do Radios Work In Tunnels?

Have you ever wondered do radios work in tunnels? Or maybe you’ve tried to use a radio in the tunnels, and it doesn’t seem to be transmitted properly. If that’s the case, then fear not, we’re here to help. After reading this article, we hope that you’ll be able to answer that question for yourself! Let’s jump into it.

Tunnels and underground spaces are notorious for being “radio-shadowed”. This is a term that refers to the inability of a radio signal to propagate properly without obstruction. Due to the construction of tunnels, there is usually a tunnel boring machine or some other large machinery that is in place, which can prevent radio transmission.

Another reason has been that there has been a lot of interference from many sources in the past, including the AMTRAK train. The issue is now resolved, and there are no longer any issues with interference between radio transmission and AMTRAK trains.

We have found to avoid the issue of not being able to use your radio in a tunnel to use a mobile repeater or radio repeater station. A portable repeater or radio repeater station can be housed indoors for indoor use in buildings. Or, they can be mounted on the outside of the tunnel for outdoor use in tunnels.

With a portable radio system found at Becker Communications that is either handheld or mounted on your vehicle, you won’t experience any issues when you’re out on an adventure and exploring.

Also, we recommend that you use a directional antenna to reduce the problem with radio shadowing. This will help to get the signal in the right direction and eliminate interference from other areas of your surroundings.

By using our Kenwood NX-203/303 Radios, you will be able to eliminate interference. If you would like to learn more contact us today!
