They think they can use little transmitters in everybody's house and
not interfere with your next door neighbor's digital TV.

That's because the transmitters listen before they transmit so they
don't cause interference, but they are incapable of listening during
the time they are transmitting.

How can a little plastic box on the floor under your computer hear the
same signal that a $150 ChannelMaster high gain roof mounted antenna
picks up from 75 miles away?
