In my opinion runing an HDZero (and also analog) receiver without an antenna is no problem.
- Because both do not send any signal from the receiver back to VTX. And only sending has some risk to grill the senders amplifier when done without antenna.
- Quite often I do not have top antennas connected when I do benchtesting with my HDZero goggles 1. And I don't have issue so far.
