Thanks for adding me to the forum.
I am building a Wifi receive-only 2-way Antenna Switch using an ESP8266 and relays. It's going to switch between an MLA-30 and my existing long-wire.
I have a query regarding the unused antenna feed that is not switched in:
Should this be:
- Left floating (not connected to anything)
- Connected to the RF ground (shielding of the output coax going to the set)
- Connected to electrical ground (-ve power supply to switch/relay).
It's going to be in the loft, so difficult for me to experiment.
Thanks in advance.
