WaruTech UHF CB Network


In the 1970's and 80's, the "Pitjantjatjara Bush Radio" was an incredible network of HF radios located in remote Aboriginal communities throughout the central western desert region of Australia.

The objective was to rekindle the 'Bush Radio' era by constructing a robust, low cost to user radio network based on UHF CB 'communicator' coverage within communities and 'mobile' coverage along main thoroughfares.  Construction of the network involved establishing 16 linked repeater sites and began with Tetracom being commissioned to supply and build the UHF CB radio network.

These mountaintop sites provide total coverage of road thoroughfares for vehicles fitted with UHF CB mobile radios.  Blue Poles provide emergency plus social access to the UHF CB radio network from strategic locations along main thoroughfares.

They feature:
- Extreme vandal resistance plus suitable for permanent exposure to the environment
- Location, function, and operation is obvious by design and signage
- Field maintainable by non-technical personnel i.e. secure but quickly removed 'talking point' panel attached to single module containing all equipment.

Remote Area Diagnostic Information Collection And Logging is a simple and low cost method of verifying UHF CB repeater network integrity plus providing immediate self-reporting of non-operational Blue Poles.  RADICAL uses automated selcall or manual
polling from any UHF CB radio.

The system:
- Regularly interrogates Blue Poles and provides fault indication and logging
- Verifies network integrity by intelligent polling i.e. Blue Pole interrogation verifies operation of access point as well as the associated repeater site and network links.
