RH6231  is designed to match the transmitter with 10 m Whip or 7-30 m Wire antennas input impedance within  1500 … 30000 kHz frequency range. RH6231 provides transformation of the antenna input impedance to 50 ohm active resistance with VSWR less than 1.4. RH6231 has waterproof aluminum housing and can be mounted with 4 M8 screws. Antenna isolator is located on the top of the device and provides connection to the antenna. RH6231 has 50 Ohm RF input connector for HF transmitter and the control cable connector (for up to 30 m remote control).

RH6231 can be supplied for marine environment with appropriate protection (as option)
