I've seen the result of just such an arrangement -- and it is not
pretty.
Mortar is extremely weak in shear. In other words, side loads of any kind
on masonry are an extremely bad idea. Your chimney will be a pile of
rubble before you get done with the preload.
Sorry to bring bad news, but I hope it saves you a big repair bill.

Subject: [TowerTalk] Guy Wire Tension and Chimneys
Bill Jones (WA2HYA)
E-MAIL: LWilliamJones@Netscape.net
I am putting up a 50 foot Rohn 25G tower and want to guy the tower to a
chimney in two of the three guy points. Does anyone have any experience
with
guying to chimneys? Each chimney is 3' by 2 1/2' and in excellent
condition.
What thickness of strap should be used around the chimney? Each would have
two guys attached according to the Rohn catalog - each guy with an initial
tension of 400#. Also what is the best way to measure the tension of the
guy
wire? Thanks in advance.
