Question about Philips TAM4505/12

Unfortunately, it's bad for me too. I constantly have to reposition the aerial. Even worse for a colleague, he gets no DAB+ at all via the same system.

I don't have reception issues, once the antenna is completely deployed. Maybe you have interference sources too close...

You probably need to straighten the antenna cable.

I also have poor reception with this device. I have now bought this antenna: https://www.galaxus.ch/de/s1/product/hama-dabdab-zimmerantenne-zimmerantenne-30-db-dab-dab-sat-spiegel-sat-antennen-6364685. But it has only improved minimally.
