RH6211-25W

RH6211 is the antenna tuning unit designed to match 25W transmitter output with 1.5-2.7 m whip antenna in HF range (1600 …30000 kHz). RH6211 provides the antenna input impedance transformation to 50 Ω active resistance with VSWR less than 1.4 . RH6211  is designed as a single board to be integrated into the radio.
