Is a satellite system still necessary in new buildings, or is IPTV sufficient?

Quick update: we are currently about 99% inclined not to install a SAT system. The decision will be made in the next few days, then I will post the result.

No RF system (whether Sat or terrestrial) can also mean poor reception. DVB-T can easily be fed into the Sat system, as well as FM and DAB+, i.e. radio broadcasting. In our house, we have such high attenuation through the walls that WLAN connections simply drop and DAB+ is only poorly receivable. With cable connections, you don’t have these problems if the antennas are installed outdoors. Furthermore, there are also converters from DVB-S2 to IP, but they still cost significantly more than a good LNC. In my opinion, the solution would be much simpler: Next to the multiswitch with two Unicable and several legacy outputs in the antenna box, lay one or two Cat6A cables, and if you want to be very generous, also lay a fiber optic strand to possibly retrofit a suitable server later. Streaming has latency of easily 30 seconds – many thanks also if your neighbor cheers at the next World Cup and you have to wait forever to find out why.

Imho the solution would be much simpler:

What please?! Pick me up at the station, I don’t quite understand...

I would also jump on the train

Unicable is a standard that makes it possible to access all transponders of one or multiple satellites on a single coaxial cable. The receiver "tells" the Unicable converter which transponder should be remodulated to a single frequency. Normally, about a quarter of what a satellite broadcasts is completely fed onto the coaxial cable because it is technically not reasonable to "push" the entire spectrum of over 3 GHz through one cable. With Unicable, it is only a very small section of it. This provides more space for other things on the cable. There is also a newer standard called JESS. Such a solution is inexpensive for multi-family houses and when using so-called twin receivers if only one cable is available. On one you can watch your program while the other records.

I only recently stumbled upon it because our general contractor's cable guy messed up and I didn't want to miss out on the advantages of our twin receivers. Otherwise, I would never have come across films like "God bless america", "Iron Sky" or "Oblivion".

Streaming hasn't convinced me yet, especially since I dislike the interest-driven bubble that inevitably forms around it. On the one hand, the picture quality is often poor and on the other hand, the data streams also like to drop out sometimes. Just great when you want to watch something exciting.

DVB-T can be fed into the satellite system without any problems, as well as FM and DAB+, meaning radio broadcasting. In our house, we have such high attenuation through the walls that WLAN connections simply drop and DAB+ can only be received poorly.

I am in favor of satellite systems, but nowadays you really don't need to feed FM and DAB+ into them anymore. There are many radio stations that can be received via satellite in good quality, and additionally there is internet radio. If your WLAN is too poor for that, then it is due to insufficient installation on your part. FM and DAB+ are, for me, only relevant in mobile contexts like in the car.

You no longer have a portable radio in the kitchen? The kind with a telescopic antenna? Grundig Musikboy?
