Anybody got some suggestions for sources for small 90-degree actuators like
this...or any other ideas for retractable antennas?

Ron Wanttaja


Mid 80's Subarus used a fairly small motor to power their center
headlight retract mechanism. Haven't looked at one in years but as I
recall they were palm sized units.........Surly you could rig
something similar with an electric motor from Tower Hobbies (or even
adapt a servo)an SPDT and a couple of limit switches?

You are correct. Ron DOES get surly when working with electrons, especially
with those moving rapidly.
