I expanded the picture in that link and the loops appear to simply be a
rebar hairpin. I don't think I'd trust that at all as an attachment
point for a 150 foot tower. And as you say, "structural fiber" isn't at
all the same as rebar.

There may be different grades or styles of concrete Bin blocks. The ones
shown here: http://www.redirockmd.com/bin-blocks/ mention using structural
fiber reinforcement which is not the same as rebar and I see no indication
of how the hook is attached. Jersey Barriers are a different shape and
pretty long I think. I could see some uses for premade concrete blocks in
temporary setups or maybe even a pier pin base but I think it would require
more research before using them for guy anchors on a permanent 150 ft tower.

I've seen the 5000 pound blocks (about a cubic yard) used for anchoring
guys on professionally erected structures, so maybe some have rebar,
some don't.
K-rail/Jersey Barriers definitely have rebar, and are often available
inexpensively - for a "field day" kind of op where you need it for a
week, they're rentable. They typically have a couple holes through them
through which you could loop a guy anchoring sling.
20 foot K-rail is 8000 lbs. (at least the ones in Southern California..
they may differ by region)
A few hundred dollars each to buy them.
