G'day
Thought I'd ask if anyone has home-brewed an antenna switch-box - because, it seems that mine has issues and I will try and explain these as best I can.
First of all, I have a 2m mobile and a 70cm mobile radio connected to the switching unit, and each radio has its own antenna socket, which in turn is connected to a toggle switch and then on to the main antenna which is on the roof.
Without the antenna switchbox connected, the SWR meter calibrates and gives accurate power readings. However, with the switchbox connected, the relevant antenna socket turned 'on' by the toggle switch, I've noticed a significant loss of power output being registered on the SWR meter.
Connecting the radio back directly to the antenna restores correct power output and a correct reading on the SWR meter, so at this point I'm suspecting the antenna switchbox is to blame - although I've checked the insides and there is not a solder joint out of place, cold or loose, all wires are correctly connected.
Wondering what could be wrong, if anything, and grateful for any help.
Cheers
