I finished getting all of the components installed into the attic this week. Without the pre-amp powered on, I pulled in 21 channels. Several had pixilation. With the pre-amp powered on, I pull in 67 channels all clean and clear. My FM radio reception has also gone from 5 static-filled stations without RDS to a station on almost every channel.

For anyone else in my area who wants to get the same results from an attic install, here is my list of what I used. This should help folks in the following areas: Collin County, McKinney, Farmersville, Lucas, Allen, Fairview, Anna, Melissa, 75069, 75070, 75071.

Winegard HD7084P installed into the attic at 12' elevation from ground, oriented to 206 degrees, 5 degree pitch, 5 degree left roll. I found the free Android applications "TV Antenna" and "Compass" set to GPS format to be extremely helpful with my installation. The compass app gives digital readouts of orientation, pitch, and roll.

Winegard AP-8700 pre-amp installed into the attic. Fixed Trap OUT because I want the FM radio stations for my FM receiver.

1.5 inch schedule 40 PVC mast running from joists to rafters.

Cables
Power adapter to power injector - 6 foot, RG6u, supplied by Winegard with preamp.
Antenna to pre-amp - 3 foot, RG6, double-shielded, GE from Home Depot.
Pre-amp to power injector - 3 foot, RG6, double-shielded, GE from Home Depot.
Power injector to wall plate - 25 foot, RG6, quad-shielded, Ultra Pro from Home Depot. I splurged three extra bucks for the quad-shielded because it had a nice waxy jacket to give me an easier pull down through the walls and because I was running the cable through a wall full of electrical lines. I was right on both accounts. Well worth the extra money.
Levitron wall plate. Home Depot.
Wall plate to splitter - 6 foot, RG6, double-shielded, GE from Home Depot.
2-way splitter - 5-900 MHz, GE from Home Depot.
Splitter to TV - 3 foot, RG6, double-shielded, GE from Home Depot.
Splitter to FM Receiver - 3 foot, RG6, double-shielded, GE from Home Depot.
