Compared with prior art, such scheme of the present utility model at least has the advantages that
(1) satellite earth antenna of the present utility model, the second sealing ring and adapter are fixed on base, the second sealing ring
Sealed base and adapter；Sealed by the first sealing ring when base and upper cover are fixed, utilize the second fixture to fix, it is possible to solve
The certainly problem of water inlet under the natural environment such as moist local aqueous vapor, it is to avoid antenna causes damage.When base is connected with connecting rod
Air inlet duct is set at screw thread, is solved the inner antenna caused when outdoor temperature generation large change by permeable watertight film
The bigger minus tolerance produced, the outdoor steam caused enters the antenna caused inside antenna housing and damages.It addition, base and adapter
Being provided with boss at cooperation, after feeder line is screwed into adapter, feeder line head contains in base boss, it is possible to prevent when the rainy day,
The wire that rainwater can cause in flowing into feeder line from connecting feeder line termination is damaged or reduces service life.
