This module can be an existing UAS 484 / EXR 504 / EXR 554 system upgrade inexpensive for Twin Receiver. The Module is the EXR laid off 504 and offers 2 Unicable outputs with 2 frequencies. Thus one can ever provide a cable TWIN receiver to the existing cables. In my case arose against the EXR 504 no degradation in performance over 15m 10 year old satellite cable. The quality is high, classic Kathrein cast housing compatible with EXR 5xx series. In sum an inexpensive upgrade that will auifgesteckt effortlessly with the EMU 50 and allows the use of twin receivers with Unicable. And cheaper than the Technisat router or the exchange of the plant.
