For more improvement of reception install a second ANT751 antenna aimed at about 215 degree magnetic compass reading.
And aim the first antenna at about 324 degree magnetic compass reading.
The 2 antennas Will Not be connected to gather on to one coax.
The 2 separate antenna and separate coaxes will go to the Tv location and be connected to a remote control A/B antenna switch.
