And when the thin epoxy resin adhesive or the high-strength adhesive is used under outdoor conditions, the aging speed is too high, so that the tightness between the protective cover and the connecting boss is easily lost too fast, and the service life of the antenna is reduced.
2. Because the central hole is only used for the antenna feeder to pass through, and the central hole needs to be sealed, the aperture of the central hole is smaller, the gap between the antenna feeder and the central hole is inconvenient to be filled with epoxy resin glue, and the filling quantity and uniformity of the epoxy resin glue can be influenced. Therefore, when the epoxy resin adhesive is used under outdoor conditions, the situation that the aging speed is too high is easy to occur, so that the tightness between an antenna feeder line and the wall of a central hole is easy to lose too fast, and the service life of the antenna is further reduced.
Therefore, it is necessary to design a fully sealed antenna device to solve the above-mentioned technical problems.
