Therefore I bought the Philips antenna. Allegedly 38dB amplifier (adjustable) and a noise reduction. Even cell phones are not to interfere. So, perfect to put the antenna next to the PC. And I've lived to receive optimal in the heart of Hamburg.
Result: In general no reception. Even when fully turning up the gain control. As my passive rod antenna has indeed found at least a couple of stations. NOTHING.
A total letdown - the morning crew returns. So much for the "quality" ...
