Steve, Using open frame relays can often lead to problems, especially in an outdoor environment in a low signal RX path.
I have well over 40 relays at my remote switching various RX antennas in the field. Over the last 10 years I have had no failures or intermittent issues using sealed small signal relays like the Omron G5V-2. Look inside almost any modern radio and you will see these same relays. I have a YouTube video showing exactly what kind of relays I use. The video also shows the construction method, schematic and I include the PCB files and a BOM if you want to build your own. https://youtu.be/Ei7q1Hy6FDk <https://youtu.be/Ei7q1Hy6FDk> 73,de steve ve6wz > On Feb 22, 2022, at 11:04 AM, Steve London <[email protected]> wrote: > > I am using an Ameritron RCS-4 antenna switch to select between beverage > antennas.
