My outdoor applications mostly involve satellite dishes. I have a couple
adjacent to the NY throughway. One uses RG 11. Installed for 5 years and
no
hint of problems.  Most problem I have are with the small offset dishes
where the weather dome points down, drain holes get plugged and it fills
with water.

I use up to 3 1/8" coax with close to 30 kW passing through it.
the lines are pressurized to keep moisture out. The o-rings help keep air
or
nitrogen in.
Bullets (connectors) are silver plated and are inserted into copper inner
conductors with no chemical additives. The outer conductor (EIA flange) is
connected with bolts. I do use Vaseline on these threads as it makes
removal
in the future easier.
