At the LNB I have four cables connected, spread throughout the house. I think so between 30 and 50 m cables are in the walls. The reception is absolutely great and I was surprised that an LNB for around 30 euros hinbekommt this because I was due to the cable length bit skeptical. I have connected 4 TVs, one of which is connected directly (Philips LED-TV) and the other by the receiver. The LNB has fulfilled all expectations, it run all 4 devices in parallel.
The reception of HD programs works without problems, but I could test only the public, as they are free of charge receivable.
The installation went as expected with no problems. Only the connection of the cable through the weather protection is a bit "fiddly". Here sensitivity is required, the effort being unsure worth. I hope that the weather protection does the job for now and I no longer have the roof. ;)
All in all, you can do absolutely nothing wrong for the price. I have been using much more expensive LNB's toying and am glad to have taken this. Therefore, from my 100% recommendation to buy.
