I need to aim a directional antenna. I think the heading to the tower is around 120* East, but I can't be sure. That's a guess looking at a map.
So what I did is found the latitude and longitude of the tower, and the latitude and longitude of the antenna in hopes that one of you guys will know how to translate that into a heading or compass bearing for me.
I have a Garmin GPS on my phone that works really nice, and I think it'll dial me right in.
The antenna is here...
Lat: 41.25791480
Lon: -81.31801401
and will be aimed at he tower here...
Lat: 41.086611
Lon: -80.641306

The second antenna aiming option is towards New Castle, PA.
1° 0' 13" N / 80° 20' 50" W

Thanks, guys!!! :tu

If your 120 degree heading is magnetic, then that would be east southeast. If you have an actual compass, I think you will have no problem.

My 120 degree thing was just a wild ass guess, and I don't have an actual compass. Just a compass on my iphone and a couple Garmin apps on my iphone. It could be 90* for all I know. Sorry, I should have made that clearer.

I get 108 deg true at about 37 miles for the first one.

That is exactly what I needed, Mike. Thank You, sir!!! :tu
The good thing is that I think the scope of the antenna at that range will pull in both, I won't need any adjustment at all.
This is the antenna I'm dealing with. (http://www.amazon.com/Terk-HDTVO-Amplified-HDTV-Antenna/dp/B0009W9WHQ/ref=sr_1_1?ie=UTF8&qid=1316902816&sr=8-1) I'm pretty sure it's Klingon.
