Most of your signals are pretty weak because the hills are getting in the way.

An attic antenna is probably not a good idea because:

1) You'll need a large antenna to make up for the weak signals and losses due to building penetration. Since your local stations seem to be coming from three different clusters (two in the west and one in the east), you will need an antenna rotator if you want to pick up stations from different directions. Your attic might not have enough space to work with.

2) With an attic antenna, you might be limited to only the strongest channels on your list (in the green and yellow zones). The channels in the red zone might not come in reliably.

3) Indoor antennas are more prone to multipath (similar to "ghosts" or "echoes") caused by signals bouncing around the building and other objects. Multipath is an additional kind of signal interference that your tuner needs to deal with and this can cause some channels to drop-out or become intermittent. Rooftop antennas have the advantage of being out in the open and above most of the objects that might cause multipath.



I'd recommend installing the antenna on your roof with a rotator and a pre-amp.

If you care about WUOA on channel 6, then you'll need a full band VHF/UHF antenna like the Winegard HD8200U.

If you can live without WUOA, then you can get something like the Winegard HD7696P or Antennacraft HBU-55. These antennas only cover channels 7-69, but they are significantly narrower than the full band antennas because they don't have any of the long antenna elements to deal with low-VHF channels.

For an antenna rotator, you can use the Channel Master 9521A.

For mounting hardware, there are multiple choices depending on where and how you want to attach the mast to your house.

A good pre-amp for you would be the Channel Master 7777.

All connections should be done with RG6 coax cable.
