> I am just about to start the installation of my new 40' Rohn 25 tower
is a brief explanation of how it will be setup and what will be on it.
can tell me whether guying the tower is needed or not. Due to the small
my back yard the guy wires would need to be adjust slightly to stay within
confines of my yard. The tower is going to be attached to a 4' short
section why will be placed into a 4' X 4' X 4" hole with 6 inches of sand
rock at the bottom and the short tower section with be set into the rock
sand about 6". The tower is going to be erected beside my detached garage
measures 20 ft to the center peak. Approximately two feet from the peak
roof I will be attaching a wall bracket which will be held in place with
threaded readi-rod to a 4' X 4" pressured treated piece of lumber that
five studs inside the garage to spread the load across the entire wall
of depending on two studs.
> Now the antenna that will be mounted on the tower which is going to be
approximately 40' is a Mosley TA-33 and a 5 element 440 antenna and a 6
2 meter antenna. So with this setup can I get by without the need for guy
Current Rohn specs allow you to be about 15' above the housebracket.
Your set-up will be at that or a little higher. The windspeed for Ramsey
County is 80 MPH. Rohn spec is 10-11 square feet @ 80 MPH for a housebracketed
tower. With an installation like you're proposing with the hefty backing
plate, you shouldn't have any problems.
