Hi Joe,
I don't have any advice. Only some words of encouragement regarding compromise
installations, and that they can yield a substantial improvement.
I live on a small city lot, no more than a quarter acre. I have tried a dozen
receive antennas (K9AY, EWEs, coaxial loops, low dipoles, etc.) over the years
looking to improve the all-important signal to noise ratio. Nothing gave a
meaningful improvement. Along came the 3 Element Array, so I thought I'd give
one a try. Everything about my situation is a compromise. I can't get a 40
foot triangle with equal sides (nor will a 50 foot triangle fit on my lot), one
of the elements is 3 feet lower than the other two, the corner of the house
blocks the line of sight between two of the elements, two of the elements are
near a metal fence and one of the elements is within 50 feet of my vertical.
Not a pretty picture. Still, the system is highly directive on 160 meters
where I spend most of my time. It provides a very good improvement in signal
to noise ratio over my vertical and has truly uncovered another layer of
signals for me. I have worked a number of stations on 160 I co
uld not hear with my BOG or my vertical. It works better than my 275 BOG most
of the time. It REALLY does work, even with all the compromises in my
situation. I am amazed at its performance and am VERY happy with the decision
to install one.
I run the legal limit with no harm to the array - a great feature. I am very
pleased with this array - and it works great all the way up to 12 meters, to
boot!.
Good luck. Do the best you can, and don't worry about the compromises over
which you have no control (I don't consider moving a viable option).

Bob/AA6VB

Subject: Topband: HiZ Install Small Lot
Hi Guys,
I will be installing my new Hi-Z 2-3 RX antenna this coming weekend. I live on
a small quarter acre lot in Maryland so I expect a few challenges and
compromises. I would like to hear from other small lot Hi-Z owners so I may be
able to avoid or workaround any issues and manage my expectations.
I will be using 3 home brewed 15 foot verticals made out of 5 foot telescoping
sections of sched 40 pvc pipe. (1.25 -> 1 -> .75) These will be painted and
mounted to a six foot cedar privacy fence and the wire will continue down the
fence 3 more feet providing me with 18 foot total length for each of the
verticals.
My transmit antenna will be very close to one of the verticals and within
50-100 feet of the other two. I know in advance this will be an issue. I'm
looking for ideas to detune it while in RX.
I am hoping this antenna will offer much better performance than my short BOG.
Any helpful advice would be welcome.
Thanks,
Joe
