>  I am just about to start the installation of my new 40'  Rohn 25 tower 
and here 
is a brief explanation of how it will be setup and  what will be on it.  
Then you 
can tell me whether guying the tower is  needed or not.  Due to the small 
size of 
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 
of the 
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 
will span 
five studs inside the garage to  spread the load across the entire wall 
of depending on two  studs.

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.
