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.

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
