I had previously a Stacker-Destacker in use to operate a satellite cable separately, both recipients of the UFS 922. Unfortunately I had to make the experience that although a connection worked perfectly, the other satellite connection but not all stations (problem with the cable cut-off frequency; for example, one festival can not be received) were receivable.
The switch to the EXR2541 was hassle, simply connect it to the pass-through ports of the multiplexer, cable and turn already done wars. Also right at the 4 LNB cables there should be no problems.
If the machine can highly recommend it, but have no experience of how it works with a receiver of a foreign company, the standard EN 50494 can.
