of power. The attachment of any external devices, such as linear amplifiers, to
CB radio equipment, for the purpose of increasing the power output of the
transmitter, is not permitted. This type of operation is a breach of the
licence conditions.
What is a Repeater ?
A repeater is a tool used by UHF CB Radio operators to
communicate over larger distances. Repeaters are often placed in high locations
like tall buildings, hills or mountains. They receive a transmission on one
channel (Repeater Input) and then simultaneously rebroadcast it over a wider
area via the repeater output frequency. With the use of a repeater an operator
can extend there range from 3 – 7 Km to over 100 K.
Who pays for the repeaters ?
Repeaters are owned and payed for by private individuals as
well as groups and organizations like UHF CB Australia. Repeaters are individually
licensed through the Australian Communications & Media Authority. Although
there are costs involved with owning repeaters, there are no costs involved for
UHF CB operators to use repeater services.
What are the Emergency Channels ?
On UHF CB Radio emergency channels are repeater channel 5 and repeater input channel 35
To access emergency repeaters:
Ensure the Duplex (DUP) button is depressed (On)
Hold the Push To Talk button (PTT) before beginning transmission
Begin transmission with "This is (Name/Callsign) Calling for any Emergency Monitors"
Release PTT and wait 30 seconds
If no reply after 30 seconds try again
If still no reply try and make contact with other UHF CB operators on other repeaters
Who monitors Emergency Channels and are they manned 24/7 ?
Emergency channels are monitored by volunteers and volunteer groups. Although these volunteers work extremely hard to provide the best service possible, it is not possible for these groups to provide guaranteed 24/7 monitoring
You have a repeater listed as Online but I can’t hear it ?
Sometimes repeater owners will switch off their repeaters
for a number of reasons. It is extremely difficult to keep track of all
repeaters across the country without the assistance of Repeater owners and operators.
If you know the updated status of a repeater or know/are a repeater owner you
can assist us by sending the details here.
Someone keeps telling me that this is their channel and I
have to move, It that correct ?
No single person or organization has the rights to use any
channel exclusively, Where possible try to accommodate other users needs and
insure you are using the selected channel correctly i.e. You are not
transmitting on Emergency, Telemetry or Repeater Inputs

What is antenna gain?
The gain of an antenna is a measure of the improvement in transmitted or received signal strength when its performance is measured against the theoretical standard isotropic radiator, whose radiation pattern represents a perfect sphere. Gain can only be achieved by focusing the radiation pattern in the direction in which it is needed by the addition of more radiating elements and/or directors and reflectors (such as in the case of yagis).
