Although I don’t have one, I would offer this advice. Waterproof the connection and have extra cable. The antenna appears to have a weirdly short UHF connector, rather than an N connector, and it’s not recessed as it would be in many professional designs. Thus, all water that runs down the body of the antenna will eventually end up at the UHF connector. Unless sealed it will eventually permeate the end of cable. Once moisture gets into the dielectric between the center conductor and the shield, you’ll need to replace the last several feet of coax and re-terminate it and then seal it.
Other than that I know nothing about the antenna and the specs reveal nothing. It’s a piece of wire in a fiberglass radome (tube). The only things that matter are does it work for your particular situation and how long will it last? The answer to the first appears to be yes. You seem satisfied. As long as the fiberglass holds up against UV and the metal doesn’t corrode and the cable doesn’t fail due to moisture permeation, you might get years of satisfaction.
