    Hey. Let me correct you when it comes to today with c band.

    I have had a few boxes at a time on my system. When I had 4dtv. Before the shut down. August 2016. I had 2 4dtv boxes and fta box. My fta box moved the satellite.
    When ever I wanted to use 4dtv. I just set my fta box to NBC. It worked and both of the 4dtv boxes did as well at the same time. And could all be on different channels.
    I use a 4 X 8 powered switch.

    Now. Today there is no reason they could not have a ton of stations on one satellite.
    Most American satellites show only 24 c band transponders.
    But the Mexican satellites have up to 50 c band transponders. Some only 4 mhz apart.
    And that could easily put us over 400 TV stations. On top of that. If we let them put the quality lower like direct and dish. Probably 800 tv stations.
    And with 16 psk. H265. They probably could take every station on all satellites and put them on one.


    So yeah they could have and do have the ability to do it.
    If you have to park on a satellite. The best one with the most stations on one. Would have to be 125w.

    And you have music choice. Which the kids would love the music video channel. It's in HD and fta.

    Can you name one? What I see is multiple uplink feeds on the same transponder instead of one combined feed (one mux) per transponder. Those 4 mhz spaced transmissions do not have the same bandwidth as a full transponder feed. You are certainly not going to get eight high quality feeds in 4 mhz.

    well... 3.75 MHz with DVB-S2 3000 Ksps, 32APSK, 8/9, 0.25 would yield 13+ Mbps
    what could be enough for one HD/H.265 channels

    The feeds to cable and satellite companies still need to be really high quality, even though most providers are compressing the crap out of them, as the better the source, the more efficient the compression is for them. Still, they could offer residential C-band service with those high quality feeds with a motorized dish or one of the large, wide multi-satellite dishes that the cable companies use to pick up all their C-band feeds with only a dish or two.

    DirecTV, as well as my local cable company, each use only one or two dishes, the main one being a very wide one that gets a whole bunch of satellites. Further, Comcast receives all their signals in Denver and transmits them via IP fiber nationwide, so the dishes you saw are old and out of service.

    Light reading from the FCC: FCC Expands Flexible Use of Mid-band Spectrum

    "The NPRM seeks comment on transitioning part or all the 3.7-4.2 GHz band for terrestrial wireless broadband, exploring market-based, auction, and alternative approaches. The Order collects information and certifications from existing users"
