new aerial fitted to s124, but has interference

[harryk]

Hi

I've just had a complete Hirschmann aerial fitted to my s124 (highly recommend Car-Masts-UK) but there is crackling/interference with the signal on all radio bands. I'm about to send the supplier an e-mail, but was wondering if anyone on here would have an idea as to why it's happening?

Thanks in advance

No, but I did the same recently and the new one does not have as good reception as the old one.
