FT20-RTC433-REPEATER

Repeater for Nokeval MTR series radio transmitters. FT20 receives the data packets sent by the MTR radio transmitters and forwards them on the radio. It automatically detects the type of transmitter, so it can be used at the same time with several different types of transmitters, which can have different transmission intervals.

FT20 operates in the unlicensed 433.92 MHz frequency band, so it can be used freely in areas where this so-called ISM frequency band is in use, e.g. throughout Europe. The device is housed in a waterproof plastic enclosure.
