Antenna system #2.
A improved antennas setup for better reception.
Do not install the AC9 antenna.
In place of the AC9 antenna.
Install a , Antennas Direct DB8e , current UHF channels 14 thru 51 antenna.
Aim 1 panel at about 265 degree magnetic compass direction.
Aim the other panel at about 190 degree magnetic compass direction.
And
About 3 feet below the DB8e antenna on the same antenna mast install a.

CS600 , VHF channels 2 thru 6 antenna.
Aim the CS600 antenna at about , 225 degree magnetic compass direction.
----
Combine the DB8e UHF antenna and CS600 VHF antenna with a.
UVSJ= UHF/VHF - Separator/Joiner.
#EU385CF.
http://www.amazon.com/Antennas-Direc...n/dp/B008PBTPN.
Connect the DB8e UHF antenna to the UHF connection of the UVSJ.
Connect the CS600 VHF antenna to the VHF connection of the UVSJ.
The remaining connection of the UVSJ , a coax goes out to the Tv/s.
--------------------------------------------------------
As a Test.
Antenna systems 1 and 2 can be Tested reception with a , Winegard ,
LNA100 Boost , antenna system amplifier connected and not connected.
http://www.amazon.com.
If only 1 Tv is connected Do Not use a splitter.
If more then 1 Tv is connected.
The amplifier will be connected -->Before<-- any splitter.

Also Know this.
As always , trees and tree leaves , plants and plant leaves , have a Negative Effect on Broadcast Tv Reception and so do buildings and other obstructions including your own , attic , roof , building , in the directions of reception.
Some and not all Negative Effects are.
Absorbing and Blocking Reception.
Multi-Path Reflecting Tv Signals Bouncing All Around.
The Best Practice is to install the antenna/s at a location that has the least amount to no amount of obstructions in the directions of reception including your own , attic , roof , building , in the directions of reception.
At your reception location the directions of reception are , West , South South West , South , North East , North West.
----
If the Tv antenna/s need to be installed at a location that provides better unobstructed reception in the directions of reception , that is not above the roof of the building , then might have to install the antenna/s at a better location.
Yes it is Ok to Test reception above the roof of the building first.
