Hi, Jim -
I don't have a KAT500, but I do have an upgraded K3 (near-K3s) with the
internal tuner that I run barefoot to a ZeroFive 30m quarter-wave vertical with
a wire attached to its tip, running about 40 feet to the north to the top of an
avocado tree. My radial field is putrid - just a couple of quarter-wave wires
for each band, because our house lot in south Florida is 1/5 acre, and I have
7.5 kV 3-phase power lines running down two sides of the property. However, it
(and its predecessor, a Zero-Five 20m quarter-wave vertical) has held up very
well in the salt air, and performed beautifully. In fact, I also have a large
coil that allows me to tune it on 630m. When using it without the 630m coil,
the internal tuner matches up beautifully on all bands from 80m through 10m.
I've always been very impressed by the construction of these antennas -
beautiful machine work, precise fittings, and very durable, so I highly
recommend them from that perspective.
I augmented my radial field with three 8 foot ground rods pounded into the sand
angled downward away from the base, plus I ran some #000to the ground screen
under the swimming pool. Typical ground resistance at resonance is about 25
Ohms.
I'm not subject to HOA/CC&R restrictions, and our city does allow amateur radio
antennas to a certain extent (60 ft max for the first tower, oneadditional
tower at 40ft), but considering we're right on the Atlantic coast, that's
pretty understandable.
(And, Florida Power & Light is in the process of moving all of the HV and
household feeders underground, so really, at this writing, I have 3-phaseHV
lines along only one side of the property, and those might have been
de-energized at this point as well; I will perform another round ofnoise
measurements when we return in November, but the noise was about S9 this winter
before they started working on the lines).
HTH and 73,
Brandy, N1HO (EL96xh)

Wondering if anyone on this reflector is using their K-Line rig (especially
the KAT500) with one of the ZeroFive Flagpole antennas? I’m moving to a new
home with HOA/CC&R crap (you know the drill - happy wife, happy life) and am
considering the ZeroFive 24 foot, 40-6 meter flagpole antenna. If you’ve run
one of these antennas and have matched it via a KAT500, how well did it work?
Did you have the KAT500 on your desk, or remote at the antenna base? These
antennas have gotten great five-star reviews on eHam.net <http://eham.net/>, so
that seems to indicate that these very expensive verticals might be a viable
solution.
