You know, I kinda thought the initial answers you got to this question the first
time (26 April) were pretty unequivocal. :-) To wit.:
"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." - K8RI
"I would not use 9913 on a crankup tower. It's way too stiff and
will bow out. Over time, the constant bending will cause the
center conductor to migrate, affecting the cable impedance."
Nobody wrote in to say they thought it was a good idea. Flexible cables like
Belden 9913F7, LMR-400, and RF Bury-FLEX were recommended for this kind of
Did you want some more opinions? OK, well, maybe you'll get some more! I'll
start by adding my two cents: No, it's not very workable. You oughta use a
flexible cable like Belden 9913F7, LMR-400, or RF Bury-FLEX.
There you go! ;-)
