I realized the only let my Antennendosen a frequency range of 50-2400 MHz.
However, the device operates between 5-50 MHz.
After replacing the outlets I now have a good connection with about 9 MB / sec.
One must be careful when you connect but really!
The device has an F-connector and there are also cables with F connectors.
Since the F-connector is usually used but signal for the SAT, is suitable for almost all antenna sockets of the F connector NOT frequencies between 5-50MHz.
With an adapter F-connector on the TV plug it should work with all "return channel capability" Antennendosen.
If you have the right doses and everything followed correctly, a great thing!
