Default Rooftop antenna tipping

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.
