Guying Towers On Rocky Terrain

[Waltk at PICA.ARMY.MIL]

Hey all.

Has anyone had experience installing guy anchors in rock?

Is drilling a a viable alternative to blasting or using
a jack hammer? Who would I contact for this type of work. 
What kind of device do I use to drill into rock about 5-6' 
at an angle of 45 degrees, your typical guy anchor depth
and inclination.

The rock is mostly Martinsburg shale. The tower will be
110' of Rohn 55G.

Any & all comments would be appreciated and I'll try to
summarize in a subsequent post.  Thanx & 73.
