There is no clockwise stop on the rotor and if you create a hard stop you'll
likely strip the plastic gear inside the motor gearbox. If K3LR's
suggestion is to have a chance of working, you would need to use the same
length of wires to each motor and use the same size antenna on both. Still,
wind and friction will likely be different causing them to go out of sync
eventually. A method of turning each one individually as suggested to
re-sync would necessary. If you are good with electronics it's probably
possible to build a new control that can turn the two motors with two
potentiometers using one setting. If the stacking distance is close,
perhaps the rings can be connected mechanically.

Subject: Re: [TowerTalk] tic ring in tandem
Hi Bob!
I have given some thought to this in the past. One suggestion would be to
set both rings (mounted on the tower) to the clockwise stop (180 degrees
south by east). Use the pot wires from only one ring, but parallel the motor
wires for both rings. Now both rings will rotate together and as long as
nothing slips, they will stay in sync. You might want to rig up a 3 pole
double throw relay where you could check the direction of the unused pot
periodically. This is a
simple method that might work well for you.

be far less money than converting the tower to become a rotating tower. If
you have done so does it work well, and do the rotators pretty much stay in
synch throughout 360 degrees? I want to stack a pair of yagi's and have no
need to rotate them independently. Thanks in advance for the observations.
