You see, if you would have a water tower like this in your backyard, all your long range problems could be solved by asking these guys to install your antenna up there...

Na that is a hot site and probably a nasty RFI place to install an FPV receiver.

Yep. Assuming that you have a long enough minimum loss feedline. Otherwise the cable up to the top will eat attenuate all your output power.

You can setup a repeater system instead. 2.4G control to the tower, then UHF from there.

At a rooftop site like that the radios go on the roof right next to the antenna with feedlines measured in inches not feet.

No just advice form a guy who has built a few dozen rooftop sites, believe it or not some of us do this stuff for a living, as for parties my motto is "it hard to leave when you can't find the door."

This is a common method for deploying 2.4 radios, note the two very short coax's installed between the Ubnt Rocket and the dual polaraity 13 dB antenna.
