Hello all. Thanks for all the previous advice. I went with a DB 4 roof mounted. Seems to be very effective. Signal strengths are excellent, even when I tested it in the house. I chose an Eagle Aspen Rotor which worked great for one day. I went to use it the second day after I put it up only to find it was not working. The antenna signal is fine from the antenna, but the rotor does not turn. There are no obvious signs of damage and the control box seems to be working. I tried the normal range or resets and realignments but nothing happened. Anyone have any experience with these? I may just take it down and lock the antenna into the Boston towers.
