Keeping moisture out of 9913 type coax?
Just wonder what other's might do to keep moisture
from getting into the semi-hollow 9913 type low
loss coax. It would seem inevitiable with changes
in temperature and pressure that moist air would
eventually work its way into the coax and then
condense.
I had a fellow ham that took the precaution of
pressurizing this type of coax to maintain
positive pressure and keep out outside air.
Seemed like a lot of effort but maybe it is necessary.
I have tried to seal the ends of the coax with silicone
sealant but I am not really sure that this has been
effective in the long term.
What do others do? What has been your experience?
