[TowerTalk] Hy-Tower base

[Bill Ogden]

I am contemplating buying a Hy-Tower (AV-18HT) but would like to mount it 
on an existing concrete pad. This pad held a TX-455 until recently, is in 
good shape, and is certainly large enough. Has anyone done something like 
this? How to adapt the Hy-Tower base to an existing concrete pad?  As 
expected, I had no response from MFJ/hy-gain when I sent them the question 
and the Hy-Tower product manual is not very helpful.
