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.
