    in the interest of being thorough...

    i climbed up on the roof and wound one of those silly coax chokes at the feedpoint of the antenna. i wanted to rule out the possibility of there being feedline radiation in the vertical plane.

    i'm still keying distant repeaters when pointed at them. i can't really tell any difference.

    just for reference: earlier in the year i build a moxon and noticed the same behavior. there was very little loss when the antenna was rotated horizontally.

    maybe i live on a forgotten indian burial mound and the ghosts mucking up my polarity.

    In hilly areas, polarity can skew as it scatters over the ridges.

    How, exactly (number of turns, type of coax, and inside diameter of the choke winding) did you make the coax choke?

    At 2m, this is incredibly critical, if you want it to actually work and not just be more coax.

    six turns of rg58 mini. its all i had on hand (that could be wound that tight). diameter was off-center. 1.5 x .75 (1x2 wood boom). i didn't whip the calculator out on this one, but i figure i'm should still be in the ballpark
