A matching device RH6227 is designed to match 150 W transmitter output with 4-6 m whip antenna in HF range (1500 … 30000 kHz). RH6227 provides the antenna input impedance transformation to 50 ohm active resistance with VSWR less than 1.4 . RH6227 has waterproof aluminum housing and can be mounted with 4 M6 screws. Antenna isolator is located on the top of the device and provides connection to the antenna with a copper braid or wire. RH6227 is connected to the transmitter with 50 Ohm coaxial cable and the control/power cable of up to 20 m length.
