Check fuses, it may have put too much overload on one of the fuses with the
extra draw from the aerial.

Can anyone help me with this.
Following several vanadalised aerials I have just fitted an electric
aerial to my '94 Astra. It worked with the engine off but when I switched
the engine on I had no radio at all. It doesn't work when the enigine is
off now either. Any advice welcome!
