Order a Radio Aerial Base, Britpart XUC100832, Online
Radio Aerial Base [BRITPART XUC100832] for Sale. This is the base that the aerial mast screws into. It’s the part that sits on the wing or the roof and connects the aerial to the radio through the coax cable. If your radio reception has gone, or you’re getting nothing but static, the base is worth checking before you blame the radio itself. The base is where water gets in, and where the connection corrodes.
Certainly, why they fail. The aerial base lives outside. Rain, salt and years of weather get into the joint where the mast screws on. The contacts corrode, the earth connection breaks down, and the signal drops. Sometimes the mast snaps off in the base and you’re left with the threaded stub stuck inside. Other times the base itself cracks and water gets into the coax. Either way, the radio stops working properly and no amount of retuning helps.
A few things to check before you buy:
-
Confirm the part number. XUC100832 is the number to match. Cross reference it against what’s on your vehicle.
-
Which model and year. Aerial bases changed across the Defender years, and the mounting hole and cable length vary. Check it suits your truck.
-
Mast fitment. The base needs to take the mast you have, or the mast you plan to buy. Check the thread.
-
Cable length and connector. Make sure the coax reaches your radio and the plug matches.
-
What’s included. Some come with the cable and seal, some are the base only. Ask.
Although Fitting is fairly simple. You’ll need access behind the panel to reach the cable, which on a Defender usually means pulling the wing liner or reaching up behind the dash. Clean the mounting hole, fit the new seal, and check the earth connection is clean. A poor earth is the most common reason a new base still doesn’t work.
One note. If you’re fitting a new base, check the mast too. If the mast is corroded or bent, or the spring has gone, replace it at the same time. A new base with an old mast is half a job.
