Glad to hear your experience David...by the way, 1/4" solid steel wire is
available here...it is cheaper than 1/4" EHS galvanized wire and sometimes
galvanized is not available...David, how do you fix the solid steel
wire???...using clamps or any other technic ???...any tips are welcome.
I have "TONS" of egg insulators, maybe if i "switch" to 1/4" solid steel
wire I can add egg insulators.
I will solve one problem but i will introduce another...corrosion will
attack the solid steel wire faster than galvanized...Imperfect WORLD...hi,
hi...
Non conductive materials like Philistran or Dacron are NOT AVAILABLE here.
Thanks,
73....Douglas, CO8DM

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.

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.
