An elementary question but -- If I want to switch a topband RX antenna among three radios, can I just use an ordinary rotary switch, without special attention to maintaining impedance, etc. 73, Pete

Pete, I have had very good luck switching between radios with rotary switches on 160. Switching between different RX antennas to a single radio can be a problem due to lack of isolation. I see somewh

Pete, If you are using each antenna on one radio at a time, then you are correct. Special attention would be needed for... 1. Sharing the same antenna on two or more radios for diversity reception,
