Hi Scott,
Braid is always a poor choice outdoors unless its under pressure
and protected from moisture such as inside jacketed coax cable
When its no longer under pressure and protected from moisture
the RF resistance of braid goes up dramatically because the
crossovers in the braid no longer conduct effectively.
That's why the appropriate choice for an outdoor conductor is
stranded wire or solid wire and never braid

Gee, it's worked for me for years. Not much salt spray in Wisconsin.

Jim,
Please ignore Scott's advice, it will cause tower corrosion and quickly fail

Or just use the braid from some RG8 and a couple hose clamps.
