So with the ANT751 antenna on the garage roof , is the house blocking reception in a direction??
Here is a antenna mount that will get the ANT751 Up High above the roof of the house without climbing on the roof of the house.

With the ANT751 antenna above the roof of the house , aim the antenna 2 different directions , about 315 and about 135 , degree magnetic compass. One of the directions will give the best reception.
Here is how to aim antennas ,

The Tv/s Must Channel scan for the Broadcast Tv Channels sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for cable tv channels.
