WUGA-TV and W11DD-D are both the same Georgia PBS , GPB Georgia Public Broadcasting and will be received by the HD7696P antenna and CPA-19 preamp aimed at Greenville.
(And Yes , a antenna aimed at the Atlanta area digital Tv stations will also receive the Georgia PBS stations/channels.)
The rest of the Georgia Digital Broadcast Tv stations/channels are weak signal strength.
And the tvfool channel list shows that the Georgia Digital Tv stations/channels have , adjacent channel and co-channel interference issues.
To receive more Georgia Digital Tv stations (other then PBS) , as a Test of reception , turn the HD7696P antenna and CPA-19 preamp to about 255 degree magnetic compass direction.
Here is how to aim antennas ,

WXIA-DT REAL VHF channel 10 , virtual number (11.1) NBC and Local Weather.
WGCL-DT REAL UHF channel 19 , virtual number (46.1) CBS.
And possibly more Georgia Digital Tv stations/channels.
With the HD7696P antenna and CPA-19 preamp aimed at about 255 degree magnetic compass , Scan for Tv channels.
Digital Tv tuners can develop - Digital Glitches - sometimes a Double Channel scan is required.

If some Georgia Digital Tv stations/channels are received - then - turn the HD7696P antenna and CPA-19 preamp to the Greenville stations and install a Winegard HD7698P antenna with a CPA-19 preamp aimed at the Atlanta area stations at about 255 degree magnetic compass direction.
The 2 antenna systems Will Not be connected together on to one coax.
Separate the 2 antennas by about 3 feet on the same mast.
The 2 antenna systems , preamps , splitters and etc. will be Separate All the way to the location/s of the Tv/s and be connected to a Remote control A/B antenna switch at each Tv location.

A/B antenna switching is Channel Surfing Friendly , Press the button on the hand held remote control , change antennas , and keep on Channel Surfing.
_______________
Putting one antenna on a Tv antenna rotator Is Not channel surfing friendly.
Must wait for antenna to rotate and not every one in the house will agree on where the antenna is aimed , Atlanta or Greenville.
_____________________________________________
Most Digital Tv's will add new channels automaticly in to the tuner memory when a new channel scan takes place.
And some Digital Tv's have manual function to add new channels.
If adding channels one at time manual.
The Real and Actual channel that is being transmitted and received is what is entered in to the tuner.
Not the , virtual number.
The tvfool channel list , list both the REAL channel and the virtual number.
_________________________
Or you can start with the HD7698P antenna and CPA-19 preamp aimed at the Atlanta area Digital Tv stations/channels and receive what is received in that direction.
And install HD7696P / CPA-19 preamp system aimed at Greenville at a later date.
