Yeah, I found the review on the ARRL web site by searching for "QHTenna".
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,
In answer to Joel's original question, there is a link at www.qhtenna.com
for questions or support for owners of existing QHTennas.
They should be pretty easy to duplicate, at any rate.

The product review is in the August 2004 QST. If you have access to the
reviews page you can find it under the "Q" listings by manufacturer.

Sounds like the "QHTennas", made by N4QH. Reviewed in QST in 2005, then he
stopped producing them just a few months later.
Near as I could figure out, they are a conventional turnstile design, but
with the 2 dipoles separated by the length of the phasing line, and no
