That 6th one down is a classic. Reminds me of this service call I did for a dink who used an old TV antenna rotor as an HH motor - and the weird thing is - it actually worked !!!! :shock:
I noticed that in Europe many people still use the actuators as h-h motor.
The one picture is moving a 120 cm Channel Master dish. and beign in Europe that meanes a lot a lot free channels
