Do I have to install all 4 antennas on the HDZero Goggle 2 if I fly analog?
Or is it enough to install the antenna for analog reception without destroying the HDZero receiver?

From what I have red or seen it uses the signal from all 4 antenna ports. This is true for analog and HDZero.
If only one antenna is installed, or will use this port mainly, due to the weak signal of other ports.
Edit: but let me try to find original source to check.

The Goggle 2 uses only one antenna for the internal module. Attached is a picture from the instructions.

Nice, I just sent a correction/reply to my initial post. Same source. 😀

So I was wrong, only left top antenna is used for analog receiver. It is in goggles user manual, hidden in a block diagram of signal processing. See attached image.
You don't have to connect any other antenna than left top. And it is neither with HDZero nor analog an issue, if you don't content any antenna. Both do not send via receiver antenna.

My question is whether an HDZero receiver (VRX) is switched off in analog mode or whether it can be harmful to it if it is operated without an antenna – like a VTX without an antenna.
@stickbro @fpv
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.

By the way, HDZero Discord chanel is quite active and helpful.
But of cause it is centralized Discord, not everyone might like it.
It is linked at bottom of their website.

But I want to support the #Fediverse. #ActivityPub is brilliant. For example, I wrote this Lemmy post entirely from Mastodon. Simply by mentioning the Lemmy community in the post. More content about our hobby might make it more interesting for more users over time. I don’t know if you replied to me on Mastodon or on Lemmy https://lemmy.world/c/fpv
