No need to drive away to do tests like that

It's way easier to do that close to,home.
With dumbly load tx antenna
I explain to you long ago not to do this test as you do

To test,for noise free stuff just do,it with out major hustle

You are right the 777 camera is very noisy but can be made useable with faraday cage just as with pixum cameras

I test this to work now

My experiments show everything can be put in close to each other

Best thing about experiments is to show others


I will show noisiest camera and how to make it work close to UHF rx



Daemon you keep on

And learnpopcorn:

There's no theoretical reason why one is inherently better than the other, beyond what I said
about external Rfi. When the Rx is near the ground, the noise floor is often lower, because
some of the external sources of Rfi are blocked by terrain. When it's high in the air, the
noise floor can be higher. On the flip side, I chose to drive right through the middle of a major
metropolitan area. (See attached)


How it plays out, is like every other part of FPV. "It depends."

BTW, I think Trappy did 50 miles or so with ezUHF with omnis on both ends of the link.
