Hamplus RS-28 Rotator Switch

If you have more than one radio room (shack), or multiple radios in the same contest station, then you probably have more than one rotator in your directional antenna arsenal. The Rotator Switch model RS-28 is the solution. These switch relay units are added to Hamplus MBD-12F  Smart Controllers in the Antenna Switch control line. They allow you to use one to four rotator controllers to control up to eight antenna rotators! They are compatible with any brand rotators and controllers. Now, it is possible to automate the entire station!
