Rotators Home Brew




This is a 9000:1 prop pitch rotator that we use to turn a five element 20m beam.  The motor on this unit is a 6000 rpm motor that runs at 90 volts DC. We found that the 24 volt motor drew a lot of current and was hard on regular relays that control the direction of it.

We had a little problem once with water getting into the unit so had to do an overhaul. We filled the unit with light weight oil.
