       Couldn't find that part number - must be an export. The catalog I have
has FSJ4-50B which is 1/2 inch Superflex. The minimum bending radius is 1.25
inches or 32 mm. If you have the regular 1/2 inch Heliax, it's bending radius
is 5 inches, 125 mm. (or approximately 10 times its diameter). The Superflex
will take more bending (that's why it's Superflex).

      The Andrew catalog is a 785 page, 4 pound treasure trove of product
info, neat pictures and lots of specs. Contact your Andrew supplier for a
copy.
