Thanks for your suggestions.
I contacted one of the professional climbers today. That guy has a lot of
experience, i think more than 20 years working with AM and TV towers.
He taught me a very interesting tip to tie the guy cable. It is different
than "cable serving" mention before that required an special tool.
I will try describe the method here:
He split the end (or begin) of the cable in 2 pieces few feet long...1 piece
with 3 strand and the other with 4 strand...then he cross both pieces and
then twist it back, so, he twist back the 3 strand piece over the 4 strand
piece and vice versa and he made a loop or gauze...then he add the
clamps...if the clamps fail for some reason the cable will not fail because
it is tie by it self.
They have been using this method plus the clamps for many years with
I will try to do a video to explain better this method.
He suggest me, like many in the list, use only one set of guy wires for a
30ft tower. Installing the guy wires about 3 ft above the second
section...it is about 23 ft high. My anchor points are 16 ft from the base,
it is about 70% of 23 ft and i have 1/4" EHS guy wire. Now, guy lenght are
near 28 ft, so, they are not resonant on any of the bands (10, 15 and 20m)
I know my base is not very strong because it is not on the ground with a
foundation...it is over a 4" concrete flag roof bolted with 4 threated rods
3/8" about 2 inch inside the concrete...i think i can improve my base adding
guy wires from each leg of the tower base to each anchor point.
Merry Xmas !!!
