[TowerTalk] How many tower sections i can install??

[Marsh Stewart]

Your English is much better than my Spanish.

14-foot guying radius is only 46% of 30-feet. Recommended guying radius is
typically 80%. At 20-feet up a 14-foot guying radius is 70%. 

Can the base (roof) withstand the downward forces of the guyed tower?

What is your wind zone? 

What size in wind-load area (how many square-feet) is the antenna system you
want to put up (including antenna, mast, and rotator)?

One possible alternative if you have enough space on your roof might be a
lower (closer to the roof) vertically oriented Yagi for your favorite band.

If possible consulting with a professional engineer would be a good idea.

Sorry for my english,

I can not change the distance from the base to the anchor points...it is 14 
ft only.

My question is:

Can install 3 tower sections (10ft long each) if my anchor points are 14 ft 
from the base ???

any idea??

Please, excuse my english.

Yes of course you can use other base sizes. 3 sections of 25g is hardly
anything to worry about and only needs guys at the top.
And then only if you don't do a bracketed install.

Hi,

I would like read your ideas.

I have few 10 ft section of a tower (it is like a Rohn 25G).

I would like install few section over some part of my roof...The roof is
concrete...as you know many house in the Caribbean has concrete roof ...it
is 24ft by 40ft...so, i have calculating and the distance from the base to
the guy anchors is 14 ft !!!

I know the distance from the base to anchor points is 70 % of the tower
height...so, 70% of 20 ft is 14ft, that´s mean 2 tower sections...right
??...Is it possible install 3 sections adding more guy´s set ???

Thanks,

73....Douglas, CO8DM
