Tom,
Let's revisit Jaan's original question:
Background:
> I have a tower that is 137ft. or 42m tall. It is triangular 1ft 10inches or
> 40cm wide. The tower is guy wired at three levels with non-isolated wire.
> The foundation is a concrete slab on on rocky ground.
> The surroundings is quite flat and conductivity is perhaps not the best.
> About 1/2 mile away I have the Baltic Ocean in almost 360 degrees.
>
> My question is what options do I have to build a good TX antenna out of
> this? What can I do? On RX side I will use separate antennas.
> I could think of isolating the guy wires or replace them for non-conductive
> type. I'm not sure if it possible to isolate the base today. Shunt fed the
> tower, use it as a folded monopole? Or should I just use the tower as a
> support for a L-antenna?

What would you recommend?

All that said and done, there are very few properly installed 160 meter
verticals that won't work well, and there are darned few horizontals that
will work better than good verticals, when looked at over a long period of
time. I can't even imagine trying to predict results or give advice when a
wire is stuck in between a bunch of random things, like conductive guylines
and other antennas.
