I had a buddy take his and slightly modify it. He took the vertical set
and optimized it higher in the band. So he had a Horizontal for SSB & CW
SWR great at the bottom of the band, and a Vertical resonant higher for
FM work, and Circular for sats, and the slight mismatch diddn't seem to
hurt it any.

To make a long story short.
Try it before you spend more money. It probably will be a good antenna for
your attic. No water issues at that location. Set it up for LHCP and with
the current satellites it will work most of the times just fine.
Why pay big bucks for a "newer" one if this will work for you.

Someone gave me an old but new-in-box version of the same antenna a few
years ago. I did a shoot out between it and the three element Arrow. I
used a ten degree AO-7 and a two degree VO-52 pass for comparison between
mode B satellites.
My tests showed the Cushcraft in RHCP did not perform better than the
Arrow. In fixed horizontal configuration, I saw a slight improvement with
the Cushcraft. In both antenna setups, I had the antennas fixed at the
horizon.
This was a crude test and I didn't use any formal measurements in my
assessment.
Overall I would not recommend this antenna for circular polarity satellite
use. For terrestrial vertical / horizontal operating I'm sure it's okay.

A student in this year's USTTI/ARRL Amateur Radio Administration course
(Ishmael, 8P6PE) has asked to engage in a satellite QSO. We're going to
take advantage of the passes we have that work with the W1AW guest operating
hours. We will try FO-29 at 1845z and VO-52 soon after at 1850z. The
passes have max. elevation at 10 and 11 degrees, but we should be able to
see the birds from the top of the relevant tower.
Mode will be SSB, and while we can't promise to QSO with everyone, we
welcome all who try.
Thanks and 73,
Brennan Price, N4QX/1

It appears I failed to correctly identify the pass times. Thanks to NJ1H
for the alert.
Sadly, we'll be in bulletin mode by the correct pass times. So no luck
today, but Ishmael promises to activate 8P on his return.

Just fired up the station. That is the same thing that happens when K4AMG
is demo at schools and events. Just not enough OSCARs in our widow FM 16US
when the students are around. But we are so lucky to have what we GOT!

It'll be great to hear 8P on the sats! I've only heard CO, YV, and PY
from down that way.
He'll certainly have plenty of hams to work when he gets set up.
