Yes, I know it's not just the height of the trees, but the distance away and I'm really only getting 50-60' away at most and the hill is steep, it's about 20° in the worst spots. This is not your flat suburban lot, it's in the foothills of the Blue Ridge. The only flat spots are where we've made them. I'll have to go out and do a visual survey to see which one actually gives more free sky from say 20° up. Right now I'm tending towards the one towards the fence because it's not on the beam mast. But I'll let this survey finish. The WX is going to be good enough the rest of the week it'll be good outside working WX.
It looks like the fence is really only 15' lower, if I put it at the arrow between those 2 gardens, I can keep the coax run at 100' and still have it up maybe 15'. http://i251.photobucket.com/albums/gg287/DogTi/time/land_zps9ee07b7a.jpg Dave It's not just the height of the trees, it's the horizontal distance from the antenna location to the trees, too -- the elevation angle above the antenna location (elevation = arctan (tree height/distance to trees) (in this case, "tree height" means height of the trees above the horizontal plane of the antenna, so it includes any difference in the ground height at the tree location, as well). At the end of the day, you want the most open sky you can get, particularly the southern hemisphere of sky, but the lowest elevations (say, under 20 degrees elevation) are not nearly as important as 20 through 90 degrees.
