Hello low banders.

My name is Jaan and I have been reading all kinds of interesting things
regarding propagation, antennas and other topics here on this reflector. I
hope to receive some valuable comments, recflections and also hands on
experience on my question.

Last winter I became active on 160 and found it very exciting with
propagation and activity on this band. What I would like to ask is what
would You propose for antenna?

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?
