From: "Jim & Velma Woods" <firstname.lastname@example.org> Also, a few miles away is a mid-sized mountain which is east of my site. I used a topo map to determine that the top of the mountain forms an angle about 15 degrees above the horizon. Is this high enough to be a concern? Thanks for your input. Jim, W7PUP email@example.com
15 degrees above the horizon is a very large vertical angle. I checked what 15 degrees means at 3 miles and computed an elevation difference of about 4000 feet, in 3 miles.
Just to check the math, is your mountain to the east, 4000 feet higher than you are?
If so...it will be a problem for low angle DX signals, as previously mentioned.
