Even at 40ft I am at 2EDGE. I would have to add a mast to the chimney.
http://www.tvfool.com/?option=com_wr...7fb91a913707a4 I am not sure what 2EDGE means, but I believe it is worse than 1EDGE and LOS. (I think it has to do with the number of times it bounces or refracts of other objects) How do you measure the height? My house faces due east and the yard slopes from front to back. My antennae is about 25 feet off the ground from street level, but 40ft from ground level. It probably doesn't matter. I am sure I would get better reception if it was roof mounted even though it might add only 8-10 feet. Right now the signal has to go through the roof tiles. I also have a hill and trees SE of me and I don't think I can get high enough to get LOS.
