Often, the least expensive and most reliable test of existing cable is to buy a new cable with factory installed connectors... Substitute the known good cable in place of the suspect cable.

If any moisture gets into the coax, you'll not be able to dry it out quickly enough to prevent permanent damage due to corrosion and contamination of the inner insulating material.

Connections that are exposed to the elements need to be protected. I have found that electrical tape by itself is never adequate. Mastic type product such as Coax-Seal® and Scotch® 2228 tape are designed to form a permanent water proof seal in applications like this. I apply a layer of electrical tape over the sealing tape only for protecting the mastic from dirt and UV.
