May '14 QST had an article on lowering antennas. It made me think of my solution.
After several attempts at protecting the antennas on my MH roof, I made an arrangement to protect them. Since then, I haven't lost one.
I can rotate them down from a sw by the drivers seat. I use an automotive window regulator motor. Mine is from a Honda. I cut off the long arm that lifts the window and bolted a U shaped bracket that I fashioned from hardware store Al stock to the sector gear. I used 5/8" threaded rod from the bracket to a hgole in another home fashioned bracket attached to the luggage rack rail on the other side. The antennas are mounted on the rod. Power to rotate, is through a DPDT CO sw (reverse polarity reverses direction). A reasonably priced 14ga extension cord is the wire used. No limit switches are needed. The motor stalls and after counting enough seconds, I release the sw.
From the pictures you can see that I added linkage to tilt mt ATAS 100 sideways.
