You don't have to point the 6M beam the same direction as other antennas
using that rotator. You could, for example, point the 6M beam 47.00308
degrees to the right (clockwise) of the other(s.) YMMV so you might
prefer a different delta than 47.00308.
The SteppIR DB42 MonstIR yagi beam has an optional dipole which is at
right angles to the rest of the antenna necessitating minor arithmetic
to compute the beam heading to be input into the controller to aim the
offset dipole.

Hi Arnie
468/f equals a half-wavelength dipole. Fed in the centre, it should work fine.
Have you looked at any of the half-wavelength loops? They're basically a dipole
shaped in a circle. They're cheap, omnidirectional and horizontal. And very
light.

I've been licensed for over 40 yrs, and in all that time I've never been on 6m! I'm
thinking about hanging a 6m dipole off of my tower. My math tells me that it should
be about 10 feet long for a quarter wave. (468÷f in mhz) Would it be better if
I put up a full wave dipole, or is there a better idea? I don't particularly want a
beam on 6 because I probably would always be pointing in the wrong direction! I have
a ham III rotor, and an explorer 14 at 60 feet and that is about all the rotor is
rated for.
