I also concur with the info below.
Go to the following website for more info on one manufacturer of the drill and epoxy products that one may use.  Phil  KB9CRY

 He wants to use the old concrete in the ground by using a  new Rohn base plate and drilling 4 holes into the old concrete and adding large  long bolts and using epoxy to hold them in. Does anyone have experience with  this approach and any positive or negative comments. thanks van 

 Yep, that's the way you do it. Rent an impact drill and bit and you're 
 good to go. Drilling doesn't take long at all. The rental place probably has the 
 industrial concrete epoxy you need too. BTW the epoxy is stronger than the 
 concrete. People use this technique every day.
