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 !!!
