I used 9913 for years and then gave it all away after one lightening strike
blew off the water proofing.  I figured it just wasn't worth the risk.

OTOH 9913 is not a good cable to use where flexing is encountered.  The
center conductor can migrate off center and it needs to make wide radius
bends if long life is expected.

I much prefer LMR 400 to 9913. It's slightly cheaper, or has been. It's one
or two tenths of a db less loss and fits the same connectors.  Both fit
PL259s. LMR 400 is more rugged and can make relatively short radius bends.
Much shorter bends with reliability than 9913. I believe (without taking the
time to look it up) that LMR-400 extraflex has about the same loss as
regular 9913, but is more expensive.

I used 9913 for years without a problem, or at least I never noticed any.  I
liked it, but finding water running out of my rig after the lightening blew
off all the water proofing was enough to cause a rapid switch to something
better.  I'd probably still be using it had that not happened.

You'll also most likely find hams who have used the stuff in flexing
situations with no problems (there are usually exceptions to most any set of
circumstances)

Good Luck,
