Next on the list would be TVS (Transient Voltage Suppression) Diodes.
Used in much the same way and less likely to go short circuit (except in the case of a direct hit).
Available in a much wider range of trip voltages, so, as Doug, says, you can get closer to the operating voltage of the rotator.
http://www.littelfuse.com/~/media/electr...og.pdf.pdf <- the two .pdf in the link is correct, I checked.
The above is a catalogue/design guide and shows how these things are used.
The only thing to remember about either of these methods (MOV or TVS), is that you need to check that they are still working at regular intervals, like say just before each storm season.
