Hi Chris,
Thanks for the input and your experience.
The concern seems to that the 36' elements on the SeppIR start 'whipping' back
and
forth while the antenna is being rotated which puts a lot of stress on the
gears when it
comes to a stop. Apparently, this 'whipping' action is not of a concern on
large beams
made out of aluminum.
73, Joe K4NYY

Subject: Re: [TowerTalk] What rotor should I use
Joe,
I have a Force 12C4 on my MA-40 and use a Yaesu 2800 SDX. Works fine for the
last five years.
Of course YMMV.
