I would agree, I always used it in the UK for 15 years with no problem and
it does not get much wetter than the UK.  You just have to take the time to
make good waterproof connections and check it every year or so.


It bothers me that 9913 coax gets a bum rap in the amateur radio 
field. I personally have used a 130' run for over 15 years to feed 
one tower and to date, there is no moisture in the cable. The key to 
use is proper waterproofing which is in the realm of all amateur's 
capabilities. The same holds true of Davis's Buryflex which has a 
foam dielectric. (Or any other coax for that matter.) You need to 
properly weather seal the connection to make sure water stays where 
it belongs, outside the coax.

FWIW, I have never had a customer either complain or return a 9913 
order for or due to water ingress.

Any combination of tape, liquid tape, self vulcanizing tape, duct 
seal, coax seal or Scotch-kote, to name a few products, will ensure 
water stays out of your coax.
