help with rotor brands
 

Hi All,
I'm searching for a rotor to use with a Flag antenna (as in Flag/Pennant).
At present I'm using an Alliance U110 tv antenna rotor.
I'm rebuilding my Flag and it will a bit heavier and has lots of leverage,
15ft each side of the mast. The tv rotor seems to have been fine in the past
but I need a control unit that is SILENT. The Alliance control unit does
the Clunk, Clunk, Clunk as the mast rotates.
I don't know any brands or specifications so all info is appreciated.
Thanks
Mike

PS. Is there a group or reflector that might
be a better resource for this question?
