With only three reviews, the AV-680 suffers because of one bad review
for an issue (MFJ/Hy-Gain quality control) that has no bearing on the
antenna's performance.
With center fed half wave slopers on 40 with the top end at 90 feet and
an angle of 45 degrees against an AV640 mounted at 25 feet well away
from any nearby objects, through an AB switch. At times the difference
was remarkable, but not always for the same antenna.IOW This was true
when working DX, be it Europe, Africa, Asia, or Oceania. At times, but
not very many, they were equal
Typically a plain old dipole or inverted V with the apex at 90 feet
would out do either for stateside.
I would assume (which is never safe) that I'd get similar results with
the AV680.

For real live on-the-air performance, you can't beat our vertical
comparison test. While we didn't test the AV-680 specifically, there is enough
real data and protocol that you should be able to make some educated
inferences from the info in the report. And only twenty bucks + postage from
_www.championradio.com_ (http://www.championradio.com) .
