I have been testing a new rotor on my 3 el 40m yagi, full size, quite heavy.
It has been up for over a month and has worked fine in nearly -30C weather
and up to 60km winds. Not a real test yet, but I feel very comfortable in
using this rotor on this size of antenna. I think it would turn the Force
12 antennas, which are much lighter than mine, with ease. It also is an
excellent choice for a side gate rotor if you are thinking of mounting
something on the side of the tower. It is a LOT less $$ than the Orion.
Where can you get a rotor capable of handling this size of yagi, digital (1
deg) readout, 6 presets, computer control, DC operation and more for only
$530 US (at current exchange rates)?
I invite you to check out http://www.alfaradio.ca/amateur.html and/or
http://alfaradio.ca/alfaspid.html
for links including a write-up by myself and a copy of the instruction
manual. These are still not "finished" but will give you a good idea of the
unit and some of its capabilities. We may also have a booth at Dayton if
things work out..
