Default Yagi efficiency

Just read your page... very interestin. We don't have large hills in
Illinois but a helicoptor pilot stated that this town is visible for
miles around and another ham told me that the DX bureu staed that this
town got more cards than all of Chicago I remember once when I gave a
local talk where I spoke about Lawson and his work and I repeated some
of his statements. Well I was challenged on some things but since I am
not a DXer they and the suurounding counties waited until a rare
station was comming on and taking only three stations from each
district. Boy I got a shock with the noise and pandemonium and couldnt
see how any station could be picked out but I was fortunate plus two in
the Chicago area. I know I was very lucky and have no idea why people
collect those things or enter contests... the noise is horrible I think
I had 13 elements on a 60 foot boom at that time plus a couple of
reflectors to experiment with. From that moment on I gave up on
aluminum elements and now use exclusively telescopic fishing poles with
an aluminum shell as it is cheaper in the long run and not susceptable
to ice build up

I don't understand. I thought you were in Indiana and wanting to
optimize your path to England.

As I said above mine is not a planar array. The computor program I use
is AO-PRO
by Beasley


That's the best there is in my opinion. You are fortunate to have a
copy since he no longer sells to hams.

Thanks for the contact The most interesting thing that I am looking
forward to is operation at the bottom of the cycle to see if there is
still propagation but only for low angles. As you gat older you look
for any excuse to stay indoors


You're welcome. Here is a long but interesting story related to low
angle TOAs. W3CRA was a legend and I can vividly remember him working
one Asian after another that I could not detect the slightest trace of
using a 3 element Yagi at 60' from my home in NC at that time:

Good luck with your new system!
