I was thinking
of feeding it at the corner, I think it will be close to 50 ohms.

That's where it must be fed. Anywhere else, and it won't act as a
half-square (except the other top corner of course).

================================================== ==

eh?

Fed at the bottom via a parallel tuned circuit works, no ? You can see my
article in Ham Radio Magazine from many years ago on how to feed it that
way, (which is really the classical feed for this antenna...the corner fed,
with all of it's inherent problems came along a lot later, AFAIK)

Simply use a parallal tuned circuit at the base of either vertical, and tap
up from the bottom (ground side) of the coil for 50 ohms. The tuning cap for
the coil can be a piece of coax (at "x" pf per foot). I ran this antenna for
years, and I had the mistaken notion that it was a "half-square". Wonders
never cease...I would have thought the editor of the mag, a seemingly
knowledgable fellow, would have caught my mistake.

very big grin, tongue in cheek
