Gambier Electronics provides a range of options for Radio Communications solutions for
clients in the Forestry, Transportation and Support services industries operating across the
southeast of South Australia and western districts of Victoria.

VHF Mid-band – Analogue wide area coverage
We own and operate a number of sites providing stand-alone wide area shared repeater
coverage that can be accessed from Mount Gambier. These repeaters provide analogue
voice communications for individual fleets of mobile radios throughout the coverage area.

VHF Hi-band – Digital trunked network
Our Digital Network operates as a trunked system that dynamically links all repeater sites
via a microwave data network, providing wide area communications across the whole
This technology allows multiple users (or talk groups) to share site repeater infrastructure
for simultaneous voice communications. Our system is readily expandable to meet a
growing client user base.

providing maximum area coverage.

Our Network repeater sites:
