Here’s my FlightAware antenna after 8months.
The glue bonding the antenna into the mount shrunk which help water get through to the connector, so you might want to seal that as well with some UV silicone(or silicone tape).

You can see the residue from the draining on the last one.
My self fusing tape held up on the connector okay, so I didn’t get water in the cable.
Thinking about it, I would probably unscrew the pole mount bracket, and move it up a bit higher, so there was better wrapping space above the N connector.
Not knowing the internal antenna layout though, that might negatively effect reception.
The nuts could use replacing too as they aren’t Stainless Steel it seems.
I switched to DPD 1090 while I had the Flightware antenna down for maintenance, and never put it back(or fixed it up).
I plan to clean it up and mount it on another mast for my backup and testing at some point.
