I have a couple of those here, about 150 feet long and they have
at times surprised the heck out of me.
My best one is made with very fine wire...2 strands of #26 I think
it is, maybe #24, telco crosscut wire it was. It is about 150
feet long and has given better results than those I have had

Lots of tall pine trees on the lot. I assume the trees in the center of the

My BOG was a breakthrough after previously using just my inverted L on receive.
Its 300 feet fed through a 300 Ohm transformer. The transformer is grounded,
but not the far end.
In the last week I added a Wellbrook loop which earned its place as my primary
receive antenna in the Stew Perry
Had so much fun in the Stew with an Elecraft K1 but it overloaded /

many strong signals. It uses a NE602 equiv. Gilbert Cell product detector.
Am thinking about a KX-3 or TenTec 539. Anyone have comments about
either on 160m ? Or some other choice ?

Dielectrics affects/increases capacitance.
Question: Has anyone made a study as to how it lowers the frequency of
the wire that it is covering?.
My thought It is probably is a linear capacitance along the wire
itself.
While the dielectric and conductors inside the shield are not
I am very fortunate that my home is located on 5 acres of land in the
country. This make for a very low noise environment.
The problem I may have is my house is located on about 21/2 acres of
landscaped land that is surrounded by a forest in the remainder of the 5
acres. The forest consists of

My marginal antenna (longwire of unknown length tuned remotely with a SGC
tuner) does not help much for AK and HI and I am not surprised that I have
never heard either location.

Pine trees taller than 100 feet could be an issue, since they could be
near resonance and lossy - a sad combination when within a wavelength or
so of vertically polarized antennas. If your trees are 50 footers, they
would probably not be of concern on 160m, but could be on 80m. For

Hi Wayne,
My QTH in the Santa Cruz Mountains is in a very dense redwood forest,

Hi Zack!
I'm located in neighboring Wisconsin, running a FLEX-5000A, and a
less-than-optimal 60 ft vertical.
I found the secret to working HI and AK from the black hole of the
Midwest. I've been able to work HI and AK many times when 160 really
opens to those areas just before my local dawn.

In rebuilding the station this year, I have been trying a lot of
receiving antennas. My criterion was: does this receive significantly
better than the transmit vertical. I tried some beverages without
success. In the past they had been good at times. I tried a low 80
