AV wireless transmitter is useless with just an antenna.
You could put a tuner in a convenient location to connect the antenna and send that over wireless HDMI or AV (no HD with AV) to your TV. The transmitter would also need to handle IR so you could change channels.
Another option is to use a Tablo tuner which send the signal to the TV over your network.

Overall running an RG6 antenna cable makes the most sense even if you have to hire someone to run it.
