I don't think the Winegard MS-2002 is the best choice for your attic location. It is a low-efficiency "omnidirectional" antenna element combined with an integrated amplifier that tries to compensate for the low efficiency of the antenna element. If the signal coming out of the antenna element is of poor quality, the amp cannot recreate a good quality signal; GIGO.

For your attic location, with a terrain obstructed path for the Fox signal, you do not want and should not use an "omnidirectional" antenna because your desired signals are all in the same general direction, and Fox is your weakest desired signal. Look at the terrain obstructions for the Fox signal on its way to your antenna:



And notice that only about 20% of its max 1000 kW of power is being sent your way.

Here is another type of profile that shows the hills:



And I see the hill in attachment 4.

The antennas suggested by ADTech are proper for your location. Yes, he does work for Antennas Direct, but he is an engineer-type person, not a marketing-type person, and will suggest the best tool for the job no matter who makes it.

You are certainly welcome to try the Winegard MS-2002, because it is your antenna system, but we feel that your odds of good reception are better with another antenna.

I see a lot of trees in your area that might block signals; see attachment 1.

Because there are so many variables involved, we are not able to give you a guarantee that our advice will work, as much as we would like to. This is an experiment.

I'd like to put an antenna in the attic. I have a total of four TVs I'd like to get a signal to.
Try a temporary setup of a Antennas Direct DB4e or DB8e in the attic aimed at 10 degrees magnetic, with one TV before drilling any holes. The DB8e has a little more gain than the DB4e, but it is larger and more critical to aim. It the TV has a signal strength indicator it will help you position the antenna. You are hunting for Fox. If NBC doesn't come in add the VHF add-on dipole kit, which comes with a combiner.

Once you get the channels you want with one TV, add a 4-way splitter for the other TVs. If the signals are too weak for 4 TVs, replace the splitter with a Channel Master 3414 distribution amp.

You do have some strong local FM signals that might interfere with the reception of NBC; an FM filter might be needed. See attachment 5.

If the antenna in the attic doesn't work, you might have to mount it outside and higher.
