Thanks for the info. I'm thinking of trying to use the
top of my split rail fence to hold a 80' wire, so I was
curious about your setup. Do you have a buried
coax leading to your shack??

Yes, both runs of coax are buried, leading into Transi-trap
lightning protectors, then up to a two way anrenna switch,
then to the Stridsburg multi-coupler, then to the
receivers.

When you disconnect the coax (say, when a thunder storm is
moving in), do you just disconnect from the switch or do you
disconnect outside?

The reason I ask is that when I had the 300' of wire, it
seemed to be a fairly decent static-charge collector. The neon
in the static-bleeder would get a pretty decent workout from
time to time. It got to the point I kept the coax disconnected
outside as the norm - connecting it only when I wanted to
listen.

I can imagine with both of your wires, your transi-traps are
worth several times their weight in gold...

I just disconnect from the switch. Never had any problems as the
antennas
themselves are directly grounded at the feedpoint through the
transformers.

You're using your 10:1 transformer for the grounding?

Well, yes. There is no direct connection between the antenna and

coaxial
cable.

Ace:

Are you using a tuner on that 200 footer?


No, no tuner. On that or the 70'.

I'm using an untuned, uncoupled,
directly connected 200 ft piece of wire which I'm thinking of upgrading.

I
currently use it mostly for LW and MW up to about 2Mhz. What frequency
range do you use it for mostly?


I use them both for everything, however my system( including the

Stridsberg
multicoupler, which was modified by Stridsberg for me), and the

transformers
themselves are optimized for SW. I can bypass the Stridsberg and go direct

to
the receiver(s), but still the transformers are wound for SW.

Other than orientation (your pic suggests 2 ants at right angles) is

there
any advantage using two longwires of different lengths?


Yes, many times I can get better reception by switching between the two as
signals arrive from different directions. Additionally, the 200' wire

works well
on many SW frequencies arriving from a W or E direction.

BTW, how tall are your supports?


9'. They are, as I recall 4x4x12 treated wood, sunk 3' into the ground.

Thanks for a usually comprehensive answer. Are you using 10:1

transformers?
