THIS IS THE ACTUAL LOCATION OF MY ANTENNA. **http://www.tvfool.com/?option=com_wr...8e03b6583ea0bb

I tried pointing my 8200 antenna north at 340 degrees and I get weak signal from the tower at 349 degrees no signal from 333 degrees. Some times the vhf at 74 miles is very strong. The same OETA channels are available 7.2 miles at 353 degrees. Therefore I don't need the vhf channel 8.
With the 8200 pointed west at 296 degrees it is still hit and miss for those channels.
Noise margin for channels at 349 & 353 degrees that are 6.2 and 7.2 miles away are 37.9 to 40.2 NM(db) I only get three of those with the antenna pointed at 340 degrees. K25JO, K32IC, and K19AA.
The NM(db) for channels at 296 degrees are 14.6 to 16.8 and 30 miles distance.

I don't know why the channels are very difficult at 30 miles and 14.6 NM(db) and up. Is my 8200 antenna to strong? Would an antenna like the HDB8X pointed in two different directions be better? I could point one north at 350 degrees and the other half to the west at 296 degrees.
It doesn't show up with tvfool but I have a tower at 288 degrees about 51.4 miles west.. That tower has channels 4, 7, and 14.
I also have the winegard powered pre amp.
