I recollect that the minimum bending radius for all coaxes is 6
times
the diameter. For 1/2" RG-8, that'd be 3 inches.


I think that's for coax with braided shield (the RG-8, RG-213) kind.

It's an Andrew standard for their non-braided coaxes.

##  as a side note, if RFS brand heliax is used, the turning radius is one heck 
of a lot less
than Andrew heliax.  The RFS stuff uses a corrugated cu center conductor as 
well as the
either cu or AL  corrugated shield.  Andrew heliax uses a copper tube on it’s  
7/8”  heliax...
and also on its 1.25”  heliax.   The RFS stuff is flexible.   IF you get the 
version with the
AL corrugated shield, it’s also very very light.  That AL outer shield version 
only comes
in 2 sizes, 7/8”  and also 1.25” .  It’s a lot cheaper than andrew....esp if 
you get it at Davis RF.
And of course, 7-16 Dins are readily available for both sizes.  The RFS stuff 
is a heck of a lot
easier to work with.

That's a bit of over-generalization. Both RFS and Andrew make standard and flexible versions of their cables. The construction is virtually identical on comparable versions.
