electrical mast please .IT WORKS FINE but no signal except on fm of course .

The mast needs to make contact with a sleeve, which makes contact with
the antenna body which is connected to the signal cable. Check the
resistance with an ohmmeter between the tip of the signal cable and the
tip of the mast. Fix as necessary, resistance should be close to zero.
