RH6214 is the antenna tuning unit designed to match 60W transmitter output with 1.5-2.7 m whip antenna in HF range (1600 …30000 kHz). RH6214 provides the antenna input impedance transformation to 50 Ω active resistance with VSWR less than 1.4 . RH6214 is designed as a single board to be integrated into the radio and it is available in two versions: with or without power reduction at lower part of frequency range, that leads to the different cost of the versions.
