I see phillystrand is still being hawked as the best overall solution for
guying where antennas
will be along the length of the tower... but I still prefer good old fashioned
steel.
The reasons - much less stretch (see K7NV's very nice analysis of same using
both EHS and
philly - no comparison!), no UV concerns (long term philly use is still not
available in great even
numbers), cost, and overall strength.
As for interaction - there is a treatise on the net by a gentlemen that I have
forgotten his name -
very well done overall on tower installations... he said in essence: for a
dipole to add gain one
has to CAREFULLY place another length of conducting material in the plane, at
the right distance,
and have the right length to JUST have a little gain... the guy wires are not
in the plane in most cases,
can be cut to be non-resonant, and for the most part are a long distance away.
I will stick with steel!
