[TowerTalk] ALIGNING ANTENNA

[Tim Duffy]

Being that the rotor is at the bottom of the US Tower - why can't you loosen the rotor clamp, set the rotor controller (with the rotor hooked up to north then manually rotate the pole (form the ground) so the antenna is north - then tighten the rotor clamp?

Dave,
In the past I've had that problem and was able to re-calibrate the rotor in the shack to show true North when the beam was pointed true North.
Only problem was that then I had lost that 30-40 degrees of rotation in that direction.  So now you would hit the stop at around 220 degrees instead of 180 degrees, if that's how you had originally set it up.  But if you have an extra 30-45 degrees of overshoot available on the rotor it shouldn’t be a problem...unless you run out of coax rotator loop!

I just replaced my rotor (with a HAM-IV) on the bottom of my US Tower 55’ flagpole with a SteppIR on top. The old rotor was off the tower for a few weeks and I suspect the wind blew the beam a little. 
    Now my bearings are about 30-40 degrees off. So when my controller says I am pointed due North, the beam is actually pointed NNW. 
    I know we could lower the tower and repoint the beam. But I’m looking for suggestions on how to reorient the antenna from the ground. 
     Any thoughts would be appreciated. 
     HAPPY NEW YEAR!
                 Dale/K4ROZ
