A complete standalone repeater site, covering radio, mast, power and licensing, delivered for a pumped hydro project in South East Queensland.

Highlights: standalone with no cellular, satellite or microwave backhaul; off-grid solar array with lithium battery storage; end-to-end supply, licensing, installation and commissioning; commissioned and ready for service in September 2025

A complete repeater site, delivered

Alongside the DMR network MarchNet delivered for the project, the client required a UHF CB repeater to support communications for vehicles and contractors using the access roads into the project area, at a remote location without mains power.

MarchNet supplied, installed and commissioned the complete site as a standalone local radio service. Because it needs no cellular, satellite or microwave backhaul, it operates independently of any external network.
