That device is illegal. 200 mW goes a lot further than 450 feet.

Dave - Both UL and CE Certified.

-wink-wink- The 200mW might be the Total Operating
Power of the Unit and not just the Output Power.

One flaw so far is that it is only 'mono-phonic' and
not Stereo.

However the "Whole House" Gold FM Transmitter is
"Stereo" -but- it only has a simple short Wire "Whip"
Antenna. which really limits it range.

The antenna on the Whole House Gold is large. It looks to be about 48"

BTW: Part 15 requires that the antenna cannot be easily modified.
