is the coax entry right at ground level? If not, use a drip loop. The
coax goes below the entry and then goes back up. All running water drops
off the bottom of the loop and none goes in the entry. Even if you get
it up off the roof, (a good idea because it extends the roof life) water
will still collect on the vertical run.
