So, before I bought the pig in a poke, I looked around in my flat. In addition to huge variations with noise filters and extendable telescopic antennas also something fancier models of eg All For One lined up in the living image. So I borrowed from the first one All For One SV 9385. Something big the device, but you must first find a proper place. After all, it is supposed to begin to look good. The reception was okay, but not spectacular. Then it must have an active antenna. I surmised. I went out and bought a last resort All For One SV 9325, which proved to be a total flop. A reception only best visibility conditions was possible to the next window. And even then, the signal quality was far from satisfactory - namely 0 usually.
Attempt Numero 2: look at what Amazon has to offer. And because the passive Mumbi antenna is offered with magnetic base for the 3 quite quickly. Here, if once distributed someone derision, that should not really be surprising. What is to be welcomed so please? The answer: everything. And doing it really well! The small Mumbi liable since horizontally on my hi-fi system, about 50cm above the ground and bring me here a signal strength of 80% and a signal quality of almost 100% when switching on the ARD. At first I wanted to not believe, why the little piece of plastic makes the same work as the active and expensive Monster my roommate. But it works and I can put your feet again.
Much more remains to be said. By Mumbi obtained much (TV) performance for very little money. Even the info: tried in Potsdam-Babelsberg. But everyone else should also invest these first 3 before they see the living room with flashing telescope stations.
