With the shown picture of the aerial interface box, check that the writing on the aerial outside (likely it will be a fixed flying saucer type aerial) is the same colour of red/orange. If it is then then you have a cost issue.
Red/orange writing, and as said most likely a flying saucer aerial, means the amp is inside the aerial and the interface box simply provides power up the aerial cable to make the amp work. The interface box will have three connectors, one for power, one for the aerial, one to provide TV signal out. There will also be two switches, one to turn power on and off, and the other to switch an attenuator into circuit to prevent picture break-up due to signal overload.
If the aerial is a newer type - likely with purple/blue writing - the amp is inside the VP2 interface box but otherwise the aerial assembly is much the same. A full replacement - Status 350 + VP2 - will cost you around £115 - of which you may have no option. You may want to contact VP (Nottingham) to confirm that the old/failed aerial has the same physical system of mounting as the Status 350.
