1) Apply a rapid setting (5 minutes) sealant like 2-part epoxy, or silicone, or hot melt glue, or similar at the point where radials enter the outer jacket of coax.

2) After installation. wrap the F-connector in tape to prevent moisture ingress. You may also use outdoor type F connector which are water resistant
