[TowerTalk] What rotor should I use

[Joe Nuccio]

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.

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.
