Thanks for all the good info. gents.

Actually 80m is not critical for me. I was really looking for
something that will work nicely on 40 - 10m (including WARC would be
nice), and have been looking over the 44' design on the W4RNL page
http://www.cebik.com/aledz.html

The plan was to mount an SGC tuner or similar under the eaves near the
antenna and run coax back through the roof, because running open wire
feeder just isn't practical in the physical situation.

I run 250w PEP SSB, but it would also be nice if the system could
handle 120w of AM because I'm into that as well. Unfortunately that
means one of the high power tuners.

I have tried a Carolina Windom (40m "Beam" version") here, but while
it works well on 40m it gets progressively deaf above that.

H'm.... all food for thought.
