Have the Fensterdurchführung used for the balcony and it works flawlessly. For the price I immediately ordered a few to more than a substitute. The satellite signal is attenuated almost not by this implementation. Have it tested by the Schüsssel I first connected directly to the receiver and then on the implementation. A large signal loss I could not find here.
The only thing there is perhaps criticized, is the adhesive property. For me, the parts remain simply not stick, but all the time come off again. Will probably still get at the hardware store something in order to better secure the implementation.
I'm curious how long such a part now holds (balcony door is in the summer open every day).
