Re: [Elecraft] Antenna for 2nd receiver

I agree, isolation is the most important factor for antenna switches. However, I wouldn’t use a switch unless it had at least 60dB of isolation in the HF band, even with Tx power of 100-watts. 73, Bob Nobis n7...@nobis.net > On Jan 2, 2017, at 20:23, Don Wilhelm
