About ADL03 UHF CB Repeater.
ADL03 is the call-sign for channel 03/33 UHF CB repeater station, located in Glenelg North, Adelaide South Australia.
This Repeater is Narrow Band. An overview of equipment used is below.
The Repeater (Ch3)
The VXR-9000 delivers the reliable performance and extended range needed. The slim-line design is crafted for easy installation and integration into most repeater sites.
High Power Output For Exceptional Reach and Performance
The VXR-9000 is a 100W commercial grade dual-purpose repeater that also performs as a rack mount base station.
ADL03 UHF CB Repeater is programmed for 5 watts output power.
The morse ID & message unit
Uses a programmable timer module and a PA voice over module with digital recorded message plus a control module.
The timer module is controlled by the interface module. Whenever the receiver is activated, an adjustable count down timer is started. This, when finished, activates the voice over module which in turn keys up the control module and the repeater, transmitting the recorded 14 second Morse ID and message on channel 3. This whole process is locked out and will not start while there is activity on the receiver.
When the message is being transmitted you are locked out of the receiver for 14 seconds. The timer starts and restarts at the end of each receiver activation. Only when the timer has elapsed with no activity will the message be transmitted.
The repeater has a 60 seconds Time Out Timer (TOT) with a 30 second penalty timer after time out.
ADL03 Repeater uses a two stacked folded dipole binary array antenna from ZCG Scalar
This is fed in to the Band Pass/ Band Reject Duplexer with six (6) cavity filters coupled together in a band-pass/band-reject configuration.
This duplexer is ideal for repeater base station applications where the stringent performance characteristics of close TxRx separations are required – such as CB Radio repeaters
The binary dipole array offers both an omnidirectional radiation pattern and genuine broadband coverage across the entire UHF frequency range. The antenna is best mounted protruding from the highest point of the structure or tower to allow for a fully omni-directional pattern.
