Part of our EVO 4 SERIES, the 2-way RFK442 RF kit is based on an FM 433 MHz communication platform. Its two 4-button RM442 remote controllers operate over a distance of up to 3,000 feet (915 meters). Outfitted with our FMH Fortin Antenna, which is equipped with a programming button and a clear blue LED indicator, this long-range RF kit is also compatible with trunk, auxiliary and valet control. That’s added convenience, for added comfort!
