Friends,
I need to really increase my country count on 160M so I've decided to
installed dedicated receiving antennas. My home is on a 6 acre rectangular
lot so I have room for a couple of 800 ft beverages at 90 degree angles or
an 8 element circular array.
I've been carefully following the
Hello Mack
My experience:
I have operated 28 years on 160 meters from the same QTH. I started out with
Beverages - which I thought worked great. The 880 foot one aimed at Europe
was amazing. So I thought.
10 years ago I started experimenting with short vertical RX arrays. Passive
elements at
Mack, I use two DXE bi-directional beverages, each 720 ft long, fed with a
single 300 ft length of direct burial quad shield RG6. The DXE transformers
and relay switching boxes use high quality weather-proof construction. That
said, the ladder line caused me nothing but continuing maintenace
Vlad,
Your message finally received here. Thank you for responding.
The situation you mention for the contest sponsors is a 'Catch 22'
situation.
They are never going to get more participation if they limit the contest
time to such a short window. And they surely are never going to get
Look at the radial field as a FAT inductor. A fat tower has a
lower Q and wider bandwidth, lower impedance at the top/far end.

Jim, Tim, and Tim,
Thank you all for some really great advice. Perhaps I should look more
closely at the 8 element receiving arrays. Are most of the 160M contest
stations now using receiving array's vs. beverages? Since I'm moving to a
new QTH I'd really like to have a best practice installation

I suggest that you study W3LPL's excellent presentation on 160M RX
antennas from K3LR's Contest University at Dayton this past spring. The
Hi Dick
I never noticed any difference in receiving performance
That's exactly what we should expect using a resonant dipole, it interact
with any other antenna because the fiscal length is resonant, does matter if
the feed impedance, if it is only a straight wire resonant it is like a

I just drafted a reply to Mack's question delineating the problem I've had with
my
vertical arrays. After I sent the e-mail, an idea popped into my head. I wonder
if
my problems have to do with ground conductivity? The soil here in New England
is poor (2 mS) and beverages are known to perform

When talking about a low dipole, the question comes up
as to why it must be low to work. Actually we don't
know that it must be low to work. Very few of us are
in a position to put up a high dipole, so the question
is basically moot. However, in an attempt to gauge the
influence of height, I
The HI-Z was erected quite aways from anything else which involved
bushwhacking and clearing the entire circle, trenching almost 1200 feet of
feedline etc so there was a lot of sweat work done on that project. But

This long answer is to validate your observation, resonant dipoles does not
provide any difference in receiver performance than your vertical or TX

I didn't say that. I said that there was no difference between a dipole
at 30 feet and a dipole at
Mack,
My actual on-the-air test and experience at my QTH in Arkansas has
revealed the 8 vertical array systems outperform beverages. I wrote an
article with graphs showing the signal performance difference over one low
band season that I can direct you to if you are interested and also

Joel,
Thank you very much for your kind reply. Do you have a preferred model of 8
element array that will perform well on 160M and 80M? Yes, I'd love to read
the article. Of course, I belong to the ARRL.
