Outstanding reception performance

We live in an area with poor DVB-T reception. After several attempts with all possible passive antenna outside and within, I had an active low - external antenna a no-name company to the roof. Even that was bad - there have always been in the mosaic picture, or no picture.

I then worried the BZD40 and mounted at the same point on the roof. The result was overwhelming and super - now all stations come on with high quality, in all weather conditions. The mechanical design is just as well - thought out and stable, with double-shielded cable, solid plugs and good sealing of the transfer. Visually it falls on the roof (screwed to the roof ladder) hardly noticeable.
Kudos to the Kathrein.
