Nice QTH, Felipe!
What are your lot dimensions?

If a permit is required, or if you want your tower to survive the next big
storm, you'll likely need to build to ANSI/TIA-222-F or ANSI/TIA-222-G. This is
going to limit the height of your 55G tower as well as the wind load that it
can carry.
Any certified Professional Engineer can help you determine what the
requirements are, and the Rohn factory web site (http://www.rohn.com) is a good
place to start to determine which of their products might fit. Then you'll know
how many guys are optimum for the wind load. If you can't place the required
guys, you're probably going to need to reduce the specifications or wind load
so to fit your situation. A local engineer can help with a plan. You're going
to want the calculations to be accurate, so design is no place to scrimp!
Good luck, post the dimensions of your lot and I'm sure you'll get suggestions.

Guys,
Im writing to get some ideas on if it is possible to install a Rohn 55
in this lot., theres another tower to the right a 125 ft rohn 45
and setting them closer would not be too practical.
Details:
I want to see how high could I go using a rohn 55
* The tower will reside on a concrete base use for self standing
* The tower will be attatched to the top of the house at 22 ft level
* As you can see I have limited space to the n/w and n/e about 50 ft
at the current angle but they could be made longer,but the angle
would be more open
* no limit on guy lenght s/e s/w
* tought of using 4 guys instead of three, since I cannot set up 120
deg guy towerds the north n/e
* antennas to be used 4 element 20 metrs monoband of 5 sq /ft 30ft
boom and a 10 meter monoband 18 ft boom and 3sq ft
* Ideally looking to install 80 ft.
* looking at sustaining 100 mph winds
Is this guying too crazy?.. any tower gurus with ideas
coordinates 18.268287° -66.082271°
Thanks
