ADVANCED POWERFUL REPEATERS
Icom’s repeaters have been designed as advanced heavy duty performers to support all types of commercial radio applications. A host of standard features and guaranteed Icom performance means you’ll need to look no further to satisfy your communication needs.
25 Watt full duty cycle operation
Employing a high performance power amplifier and effective cooling system, the IC-FR3100/FR4100 provides a stable 25W at full duty cycle operation.
Automatic battery backup system
A built-in backup system supports automatic switching to an external power supply
(13.2V DC) if the AC power supply fails.
CTCSS, DTCS, 2-Tone, 5-Tone, DTMF encoder/decoder
Multiple signaling systems are equipped as standard. These systems are fully compatible
with Icom F-series radios.
Internal space for duplexer and isolator
The repeater has an internal space to install a duplexer and isolator*. The controls
of the duplexer are accessible from the front of the repeater without disassembly.
Faster and easier maintenance and adjustment is possible.
