[TowerTalk] Non resonant guy considerations

[Patrick Greenlee]

August gentlemen of the elevated antenna mounting structures fraternity, I 
would like some technical advice (and anecdotal reports are also solicited 
as well) regarding the necessity/effects of breaking up the guys for a tower 
used for VHF and UHF into non resonant lengths.  The subject tower is a 
tilt-over/crank-up tower consisting of two 20 ft sections and a tube mast at 
the top to gain back the length lost to overlap and have antennas mounted at 
least 40 ft AGL

This tower is intended for use only to support VHF and UHF antennae but may 
have a non conductive connection (black Dacron antenna rope) to assist in 
holding up a wire antenna or portion thereof in the HF bands. Any thoughts 
on how far the antenna wire needs to be from the VHF and UHF antennas.  HF 
and VHF/UHF will not be in use simultaneously.

At some point as freq goes up breaking up the guys into ever decreasing 
lengths is not standard practice, e.g. microwave and cell towers.  So, any 
advice as to approximately about where in freq this "happens" for ham bands? 
Yeah, I know, how high is up and how long is a ball of string...

TIA for your consideration and 73 de
