[TowerTalk] anchoring to rock

["Rudy Severns" <n6lf@arrl.net>]

My QTH is also built on solid rock which is only a foot or two under the 
soil.  When I put up my two self-supporting towers (54' and 89') I dug down 
to the rock surface, drilled a number of 1-3/8 X 18" holes, placed rebar in 
the holes set with anchor cement for machinery mounting and then poured a 
slab over the lot.

It has worked very well despite high winds on occasion.  It also save me a 
small fortune in concrete expense.

73, Rudy N6LF
