A tactile rotor is ideal.

However,
If you time the total 360 degree rotation time, then you can work out your
beam heading from a fixed point.


In practice, peaking the signal is the main pointer, unless you want to beam
in a particular direction, in which case, you take your rotor to either end
stop, and make the timing from there.

On HF, the band noise changes when you rotate to a point where the crackly
noise becomes more smooth at a point in which the band is open.

Hi;
Most 2 meter beams will manage quite nicely with a tv rotator.  They have 
various control boxes so you want one with some sort of tactile pointer. 
You might want to just stop at you local radio shack and go shopping.  A tv 
style rotator should be fine.

Hi list.
I Have a 2 meter beam that was given to me I plan to put up.
I haven't seen it yet, but I believe it's a cushcraft or how ever you =
spell it.
I don't know the model or how many elements it has.
What I'd like to find out is what is a good rotor for it with out to =
much over kill on price or wind load.
Also is there a way to control the antenna with a computer.
if so how do I do it and if not what is a good control box not to =
expensive.
Thanks in advance and 73.
