I have already reported on my bad radio reception and recently went on the search, but I found no mistake. Got a rear window antenna. Is there any way to improve the reception without installing any other antenna? If not, does one have a good suggestion for another antenna, which you might even be able to mount in the interior? Or simply propose everything, can still decide

Greetings Simon
Wenn du die Spannung wegnimmst und der Empfang dann noch schlechter wird scheint der Verstärker zu funktionieren.
