[TowerTalk] What rotor should I use

[Dick Dievendorff]

Maybe a different rotator controller with a different ramp-down speed
control could be helpful.  I really like the Green Heron controller that
came with my K7NV Prop Pitch...

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.
