Topband: deterioration of RG-6

[Robin]

Use flooded cable- its air spaces are flooded with goo that does pretty
well at keeping water out.  Flooded cable is available from many
suppliers - quad shield flooded cable is pretty standard for the cable TV
folks.  If a section of the line gets damaged, the goo will mostly keep the
water from wicking along the cable and killing the whole run

check with whatever supplier you use, or do a search for flooded RG-6 &
pick the best price for you

DO use the correct connectors
