Kutta Radios Represented at the first MTE Expo by Ghata
This year, MTE is raising the bar following a good end to 2018 – two new expos are included in the 2018 calendar – with the inaugural Lichtenburg and Ngodwana expos taking place in North West and Mpumalanga provinces respectively.
MTE continues to grow and expand into other sectors alongside mining and owing to its involvement in the sector, MTE has seen continued success. Its engagement has seen MTE establish long-standing relationships with both mines and exhibitors. MTE prides itself in face-to-face market research that is conducted when the team prepares for each exhibition.
With 26 years under its belt, MTE is established as the leader in organising and hosting travelling exhibitions in a variety of sectors, which reflects the brand’s growth and versatility. MTE’s success is attributed to the relationships it has with mines and exhibitors, an excellent team of dedicated individuals, its growing footprint in Africa and its consistent delivery of high quality and high impact exhibitions. With all these elements combined, MTE’s continued success in future is guaranteed.

MINE SAFE 2017
Advanced Comms was one of the main sponsors of the Mine Safe Expo 2017. At the conference the company revealed the amazing Kutta Radios and the WARN device.
The conference focused on improving health, safety and the environmental impact in the mining and metallurgy industry and highlight actions to be taken.It acted as a platform for learning and allow people to share ideas on safety, health and the environment.This conference aimed to bring together management, DMR, Chamber of Mines, Unions and health and safety practitioners at all levels from the industry to share best practice and successful strategies for zero harm and a value-based approach to health and safety.It addressed the main challenges in the mining industry such as logistics, energy and safety of employees, contractors and the communities.
TECHNOLOGY OVERVIEW
Kutta Radios provides next-generation medium frequency radios to mine operators as a reliable, cost-effective solution to communication and tracking needs. Kutta DRUM® radios use cables, wires, tracks, and pipes to create survivable, redundant communication paths underground that extend for miles. The DRUM® is a wireless medium frequency radio system that works whether mine power is on or off, post-incident, and even through obstructions.
Kutta DRUM® radios use parasitic propagation of a medium frequency signals to send voice and data communications in an underground environment. These signals magnetically couple to metallic items commonly found in the infrastructure of a mine, and allow for voice and data transfers several miles in distance. When proper conductors are present, signals can travel over 5 miles in distance non-line of sight. These point-to-point communications can be carried by conductors such as: leaky feeder cables (powered or un-powered), phone lines, power lines, lifelines, metal pipes and tracks. Conductors that are even buried beneath the earth can continue to transmit medium frequency signals in many scenarios, making the DRUM®Communication System the ideal redundant safety communication system for mine operators.
USE CASE EXAMPLES
The following presentation highlights several possible use case examples of the DRUM® Communication System, including;
- Redundant UHF / VHF Communications
- Survivable Leaky Feeder
- Leaky Feeder Extension
- Bleeders & Hard to Reach Areas
- Mine Rescue
- Rescue Chamber Communications
OUR PRODUCTS
DRUM® Compact Portable (CP) Radio

The DRUM® CP Medium Frequency Radio is a battery powered, digitally controlled, analog frequency modulation, single-channel voice communication radio. It uses a two-element omnidirectional magnetic induction antenna operating in the medium frequency (MF) band to propagate its signal parasitically across metal infrastructure in an underground / tunnel environment.
Under normal operating conditions, signals can be relied on to propagate many miles between the sending radio and any receiving radios with little attenuation. In post-incident emergency circumstances, when conductive infrastructure has been altered or damaged, the units can be moved to propagate their signals on surviving conductive infrastructure, forming a survivable redundant communication path.
The DRUM® CP is compatible with the DRUM® Repeater Units, in that it can send and receive voice transmissions interchangeably with the DRUM® Repeater’s MF interface. The product is lightweight, rugged, and man-portable.
DRUM® CP – Features
- Lowest Cost-Per-Foot of Any Communication System on the Market – By Far
- Fulfills the MINER Act Requirement for a Redundant Communication System
- Seamlessly Interoperates with Existing UHF / VHF Leaky Feeders and Handsets
- Supports Point-to-Point Voice Range of Over 5 Miles Underground
- Communication in hard to reach spots, temporary working areas, and bleeders
DRUM® 100R – Medium Frequency Repeater

The DRUM® 100R Analog Repeater is a dual-band radio, where one of the front ends operates at medium frequency and the other front end operates at either VHF or UHF. The analog repeater continually listens to both frequencies. When one of the front ends detects an incoming signal, the analog repeater shifts the signal and retransmits it on the other front end. Tone squelch is used to indicate the presence of a valid signal.
Under normal operating conditions, signals can be relied on to propagate many miles between the sending radio and any receiving radios with little attenuation. In post-incident emergency circumstances, when conductive infrastructure has been altered or damaged, the units can be moved to propagate their signals on surviving conductive infrastructure, forming a survivable redundant communication path.
DRUM® 100R – Features
- Installs in Hours – Complete Install in Less than One Day
- Extends the Range of Leaky Feeder with No Extra Wires or Cables
- Voice Data from VHF or UHF Handhelds will be Transmitted onto the Leaky Feeder
- Trolley Phone Replacement
