Hi Rick,
I'd agree that a tactile control is probably the way to go and a TV rotor is
all you need for this beam. If you go to RS you should at least be able to
get your hands on it and see if it suits your needs. Both Alliance and
Channel Master made rotors with a knob that has a mark on it. You turn
the knob till the mark points to the heading you want and the antenna
follows. There are still a lot of them floating around at hamfests and
perhaps online Maybe Norm's Rotor Service or The Rotor Doctor can help..
For computer control you will need a true ham type rotor and the added
stuff in the control box. Even in a used condition you are looking at a few
hundred bucks for rotor and computer controllable box.
This may not suit your needs, but I'm using a CM 9521A TV rotor from
channel Master. It's in current production and sells for about $80 (maybe
less if you are a good shopper). Includes rotor, control unit, and remote
control. The small control box has a 3 digit red led display and cw / ccw
buttons. With some usable vision you just hold in one of the buttons till
the heading you want appears in the window. I can't see mine, so I just
use the included remote control. Enter a 3 digit number between 000 and
360 and the antenna goes to that heading. You can also program up to 69
memories. Program the heading for a particular repeater or friend in and
recall that heading any time. The control box clicks when rotation starts
and again when it stops, so you have some Idea of what's going on. Using
mine to turn a rotatable dipole for 10/15/20 meters.
73, Steve KW3A
