Bracketing a self-supporting tower.

[Gene Smith]

If I put up a 40' to 50' self-supporting tower
and bracket it to my house at about 15' just
for a little added strength, will bracketing
it cause any problems?  This would not be a crankup.
It would be Rohn 25G/45G, Universal aluminum,
Titan, etc.

I ask this because the bracket would cause additional
downward force and less upward force on a tower
and concrete base system designed for equal upward and 
downward forces.  At least I think they would be equal.
