This automatically tunes your antenna as you tune your radio. SWR is just always low. It can tune your coax-fed or random wire antennas from 1.8 to 30 MHz from 2 to 200 Watts SSB/CW. It matches 6-1600 Ohms (SWR up to 32:1) and is made in the USA. the MFJ-939 is learning your antenna system as you operate and storing this in its 20,000 memories. The more you operate, the more it learns. This tuner measures your antenna’s complex impedance (R, X), computes the L-network and engages needed components for instant matching. The interface cable for Icom is included.
