Default Isolation of guy wires

Has anyone thought of trying to use some of the ferrite beads to
isolate the guy wires of a tower for RF so the tower could be shunt
fed ? Along the same lines could the beads be used to electrically
brake up the wires into non resonate lengths ?



It would require multiple beads at each point, and at multiple points.
While it could be made to work, it would be heavy and expensive. That's
why egg insulators or non-conductive guys are used instead.


However, such things have been done for stuff like the electrical power
drop to your house.


I believe Jim Brown's website has a picture of where he's got a bunch of
clamp on ferrites on the feeder for this sort of purpose (because,
obviously, a insulator wouldn't work)
Check figure 31 on page 23 of http://audiosystemsgroup.com/RFI-Ham.pdf
