[TowerTalk] Securing a Rohn BPL45 Base Plate

[Byron Tatum]

Hello-
   I plan to install a Rohn 45-G tower on an existing concrete base. (The concrete base is actually larger than the base specified for my planned height.)
   I wanted to ask what would be an acceptable method of anchoring the base plate? I know that for a newly-poured base you would install the 3/4" x 12" pier pin. Would a strong 3/4" concrete anchor bolt be acceptable?
   Thought I would ask as I have never been faced with this.
        Thank you,
           Byron WA5THJ
