Hello all,
Now that I was remionded to look, my qhtenna units came with a 1 page assemby instructions and drawing that includes lengths of rods and phasing harness. I'd be glad to scan/post it somewhere if anyone wants it.

I would suggest that you don't need a phasing line if the dipoles are spaces a quarter wave and that both are fed by equal length cables.

Looking at the pictures, it appears that the dipoles are separated by about 1/4 wave in free space, which is physically longer than a 1/4 wave phasing line would be. And I'd think that the phasing line would have to be 1/2 wavelength, after introducing a 1/4 wave offset between the dipoles, correct?
