Yes. You are, after all, using a TV frequency for the wireless. So
using a TV antenna tuned to that channel can be a good choice.

Who pays the bill for the lighting? If the electric meter is on the GM's
property, there has to be a conduit going out there.
Running 70V audio through a power conduit is not a real good idea, but
you can do it, the code will allow it, and it can work.

AHH! Okay, it is a point to point link, but the transmitter is being
moved into different locations, right? You move the camera to where
it wants to be, then point the antenna at the receive antenna array below
the booth. Except that they aren't pointing it. Is that it?
Is this a semi-pro group or is it minor league? The minor league guys get
very upset at being called anything else....
