The centerpiece of the UHF Liberty Radio Extender System is the ultra compact Ritron Liberty
UHF Repeater
(model RLR-460) and the included Liberty antenna.
The UHF Liberty repeater operates in the 450 to 470 MHz FM communications band and has a maximum output
power of 2 Watts. The repeater and its antenna receive signals originating from either a portable, base station or
callbox on one frequency and simultaneously retransmits (repeats) the signal on a second frequency. Because
the repeater “automatically” retransmits the signals it receives, it will operate unmanned. This automatic re-
transmitting of signals combined with the ability to remotely mount the Liberty antenna in an optimal location,
makes the Liberty Radio Extender system a powerful on-site communication system. In general, communication
systems that utilize a radio repeater, such as the Liberty repeater, enable radios to achieve better coverage,
better penetration and longer range than is possible without a repeater.
All radios included in the system have been have been specially programmed to work together as a system. If you
wish to add-on additional radios to your system, they must operate in the same frequency band as the Liberty
repeater and be capable of repeater operation (see system frequencies below).
See page 3
