Hello All:=20

I have a tower question that I hope someone can help me with. I am =
installing a ROHN 45G tower at my QTH. I am planning to use a house =
bracket at about 15 feet above the ground. The bracket is bolted through =
the brick into the top 2X4 plates of the house wall where the roof =
trusses attach. The tower base section is seated in a 30X30 inch by 4 =
feet deep concrete base.=20

My question is, how high can I safely go without having to use guy wires =
on the tower? The proposed antenna is a tri band yagi with a wind =
loading of 7.5 sqft.

Thanks in advance for your help.

73, Mark...   =20
