other
coil turns.
Since this is a series coil at the base, I will use a shunt coil to match the
swr.. I hope that is what I am going to do and not blow up something else .

Conductivity of Copper: 5.85 x 10^7 mho/m
Conductivity of 301 Stainless: 0.14 x 10^ mho/m
Stainless is 42 times worse conductor than copper.

A couple of us in Maine also worked Joe WL7E this morning but the LP direction
was closed for us. Instead, Joe was worked via the conventional NW path for me
with the HI-Z array. There was some slight copy to the West direction but I
attribute that to pattern overlap on the vertical RX array.

Hello all..This AM on 160 meters there was a station CQing on 1.820.6 with
a fundamental freq signal strength of S9 on my K3. I also found (with the NB
on) that I could hear him Q5 but very weak on 1.810.6 and the same S 0 reading
but perfectly Q5 on 1.830.6. I turned the noise blanker
Larry, As has been noted... worth a look and invokes serious thought on
how to administer DXCC and other Awards within a constantly evolving Radio
environment.

Could someone tell me the length of top loading wires (4 wires planned) needed
to add to the top of a base insulated 90 foot Rohn 25g tower to maximize the
radiation resistance on 160 meters. I understand there is a point of
diminishing returns on the top loading lengths. The 4 wire angles

I have a couple questions I have never been able to find any direct answer
for... so... out of curiosity...
1: I have never found or read any information concerning the best way to feed
a base insulated tower. Is it better to just feed one leg from the matching
network or would it be better
I will keep trying low bands daily within the next 2 months. In the beginning
of March I will remove all antennas and leave. It was good DX-pedition, but
hope to do a bit more on low bands especially. Did not have so good setup and
opportunity to install many antennas when I was in Iraq as
