Yes, thanks to a penny-pinching local ham! This guy talked a bunch of
his buddies into kicking in for a 500 foot spool of "Genuine RG-213
Mil-Spec" coaxial cable, at about 1/3 the normal price. When it
arrived, I saw that the cable was stamped "RG-213 TYPE" and "MIL-C-17"
every foot or so. One of the buddies made up a short jumper cable for
my radio club, and it worked fine for about a year. One day, I switched
the jumper to another radio, and the the PL-259 connector came off in my
hand!
I dissected the cable, and found that it was made with aluminum braid,
and the solder naturally did not adhere to it. The shield coverage was
far less than genuine RG-213/U, probably something like 70%.
The kicker was that the manufacturer was not listed in the military
Qualified Products List (the "QPL") that identifies ALL suppliers of
GENUINE RG-213/U cable that meets the MIL-C-17 specification. Any
cable that is similar to RG-213/U but does not meet the specification is
supposed to be marked with the word "TYPE" to indicate that it is
non-conforming. Unfortunately, many unscrupulous vendors leave off the
word "TYPE" on their junk cable, and there seems to be no shortage of
unwary buyers!
In your specific case, perhaps your "Cursed Coax" should be replaced
with RG-214/U double-shielded cable or Andrew LDF-2 or larger Heliax.
