You did not say if this was the length of guy wire you will use or
the spacing between insulators.  In either case, the self resonance
is very close to 10M and may act as a director on that band, especially
if that represents the wire length which will be end loaded by the guy
grips.  For this reason, I use 12 ft between insulators close in to the
tower, after the first insulator which is spaced 3 to 4 ft from the
tower.
