Wow.. lots of info. Got tied up at work this week. I have a mobius mini 1080 that records to SD card. I use it on a car for various shots. I do not have go pro, or any apple products.
I think my TV still has at least one composite cable input. I bought an Ebay kit many years ago, and it was useless. Thought stuff would plug into an HDMI port. Doesn't have to be 1080..
But since I will not have clear line of sight on r/x to t/x at all times.. I would need to run multiple antennae for clean signal, or something lower than the 5.8ghz... My furthest point from base would be 20ft, and 2 walls.
