OK, that's a good point. Looks like I'll get Rohn's hinged flate base
plate. I wish they had one that wasn't hinged as I don't need it. But I
never thought about the issue of rusting. Why just a single bolt and not
multiple bolts? A friend who suggested the flat plate method said to have
nuts screwed onto the bolts in the concrete and then have the base plate set
on those nuts. That way, you get the plate off the concrete and keep
water/moisture away from it. This is the way you see cellular monopoles
installed, light poles, etc.
Is this how you'd do it or would you do it differently?

It's a split level. The edge of the roof is perhaps around 15 feet above

OK. That's what I figured. So even though I will have shorter guy wires
and steeper angles on them, that's OK. Correct?

Well, we've done a couple and the darn things just don't want to fit
together too well. Diffculty lining them up, etc. I am afraid that once I
slip them together, they won't come apart very easily. Any suggestions for
making sections slide together more easily? WD-40 or some other lubricant?

That's what I figured. I've thought about making my own, but wonder if it's
just better to invest in a good ready made one. Anyone have any links or
anything to plans for making your own?

That's what I was thinking - a full body harness. Yes, two lanyards is a
73 and thanks for the reply,
