[TowerTalk] quick question

[W0MU Mike Fatchett]

Other than cost aren't there tilt over bases already made for these 
towers?  Telphone poles were not made for that purpose.  I sure would 
not want to risk killing my friends and family members over $1000.00.

Do it right and do it safe.  This is a hobby.
