A type N connector is pretty much waterproof. Place a type N connector in
the coax at the base of the tower. Use a barrel connector to connect the
coax from the tower to the shack. You can apply a grounding kit to the
barrel connector then use the rubber tape to seal it all up. About as good
a ground as you can get an you will not flood the coax with water when it
rains.
