The Icom IC-FR4100 is a robust UHF FM repeater designed for professional communication systems. It operates within the 400–430 MHz or 450–480 MHz frequency ranges, offering 32 programmable channels with 12.5/25 kHz spacing. The repeater delivers a stable 25W output power, ensuring reliable full-duty cycle performance, even under continuous operation, thanks to its efficient heat sink, cooling fan, and high-performance power amplifier.
Equipped with multiple CTCSS and DCS tone memories, the IC-FR4100 supports up to 16 independent tones per channel, facilitating secure and interference-free communications for various user groups. It also includes built-in 2-tone, 5-tone, and DTMF encoders/decoders, ensuring compatibility with Icom F-series radios and enhancing signaling flexibility.
For uninterrupted service, the repeater features an automatic battery backup system that switches to an external 13.2V DC power supply in case of AC power failure. Installation is versatile, with options for wall or 19-inch rack mounting using the optional MB-77 and MB-78 brackets. Additionally, it supports remote control via DTMF, facilitating convenient operation and maintenance.
Ideal for enhancing coverage in private mobile radio (PMR) networks, the IC-FR4100 is a reliable choice for expanding communication range and ensuring seamless connectivity in various operational environments.
