I would love to set up a system like this to supply video signals to sets in my "tv room" as well as portables around the house... but is it legal?
"Unlicensed broadcasts on the TV broadcast bands are prohibited, except for certain medical telemetry devices. 87.5 to 88.0 MHz is considered part of the VHF TV band (channel 6 audio is on 87.75), though it shows up on most FM tuners. For TV, 15.241 and 15.242 deal with high VHF (channels 7 to 13), 15.242 also deals with UHF."

I believe the 100 milliwatt rule only applies to transmitters in the AM band, with very restricted antenna length.
If I set up such a system, will I be a Pirate?
