The group of Tv stations to the north/west has the most Tv channels.
If you will like to have a look at the Tv stations/channels to the south at about 180 degree magnetic compass.
Turn the HD7084P antenna to receive those Tv stations channels.
If those Tv stations/channels to the south look like you will like to receive those then install a separate antenna system.
Install a Winegard HD7698P antenna with a Winegard AP8275 preamp.
The 2 antenna systems , the north/west system and the south system Will Be 2 Separate Systems and Will Not be connected together on to one coax.
The 2 Separate Systems Will Have Separate Coax all the way to the location of one Tv.
And separate splitters and coax if more then one Tv is connected all the way to the Tv's.
Thats double the coax wiring.
And at each location of the Tv/s will be a remote control A/B antenna switch ,

The A/B switches are channel surfing friendly.
The other way to do it is put the HD7084P antenna on a ,

Antenna rotors are not channel surfing friendly , must wait for antenna to rotate.
