One of the guys on the other group I belong to brought up how some of the drive-in theaters he worked with operated their system. They had a transmitter that they hooked up a long run of "leaky" coax to with a 50 ohm resistor at the far end. The coax was buried under the field where the cars parked and radiated along it's entire length. No one place exceeded Part 15 limits but the whole area had enough signal to be picked up on all but the worst car stereos.

That makes a lot of sense, and it makes it far easier to keep the signal inside the fence so outsiders can't watch and listen for free.
