We are installing a pole/mast for wireless communication equipment on the roof of our commercial building.
The pole will need to rise 2m above the roofline. Obviously we want the pole to be as securely attached as possible.
This is our current plan of attack:
Buy a 3m length of galvanised pipe and have it extend 1m below the roofline, parallel with a reinforced concrete column (part of the building structure).
Pass the pipe through two attachments, which I'm not familiar with the name of. They are like a pipe clamp with a plate welded to it. One near the top of the 1m overlap with the column and one near the bottom.
Fix each plate to the concrete column in four places.
Attach three guy ropes to the top of the pole, one away from the concrete column and one in each direction perpendicular to that. The guy ropes will be fixed to parts of the building structure and a turnbuckle will be used to tighten them hand-tight.
Does this sound like a secure way to mount the pole and the guy rope ends?
I have heard that epoxy glue-in bolts are more secure than Dynabolts (expansion bolts) and reduce the risk of the concrete cracking. Is this true? Are there any resources I should read to use epoxy glue-in bolts correctly?

You may want to consider one of the various style of commercial bracket assemblies designed to mount antenna masts onto chimneys and concrete columns. Here are some examples:
