[TowerTalk] Can´t add egg insulator...

[David Robbins]

It isn't that important to use non-resonant guys.  I have 4 guyed towers with solid steel wires and stacks of yagis for 10m through 40m and everything works just as it should.

It is VERY important to use non-resonant steel guy cables on your frequency(s) of operation.

A resonant guy cable will have adverse radiation patterns during RX and TX.

A good example... my guyed tower was constructed years prior the 60m band was introduced.  
My tower is guyed at three levels.  Numerous preformed grips and egg insulators were used.

I rigged up a 60m dipole antenna. During the tuning process, as I neared the resonant frequency, the SWR suddenly sky-rocketed.
Reason - two of my guy cables were resonant within the 60m band.  I scrapped the 60m antenna.


Thanks n 73,

 Hi guys,
 
 I read about resonant guy wires.
 
 Unfortunately i can´t add egg insulator to build non resonant guy wires. I don´t have enought clamps or guy grip (preform) to install egg insulators.
 
 Maybe someone know any other solution.
 
 I have been modeling my tower on MMANA and i don´t see any interaction with my HD spiderbeam for 10, 15 and 20m.
 
 My guy wires lengths are: 20 ft (the 1st level ) and 30 ft (the 2nd level).
 
 any tips are welcome.
 
 73....Douglas, CO8DM
