Re: Scary VHF Hi Band (174-216 MHz) is prime real estate for HDTV. You can use solid-state amplifiers for high power, not possible with UHF, where you have to use Klystrodes, etc.
The main problem with these unlicensed devices is the fact that the FCC failed to mandate a receiver standard for HD TV sets. The HD tuners already in homes are very cheaply made and are quite vulnerable to 3rd order intermod interference. These unlicensed devices can cause interference to TV stations several channels over, not just on the co-channel.
This guy has done the math, and it ain't pretty:
