Does it mean the universal LNBFs won't work with the 4:2:0 and 4:2:2 signals? That's what I am trying to find out.
The previous replies are correct. The LNBF does not differentiate between the types of signal received. Only the frequency and polarization of the downlinked signal is important for the LNB.
If you consign Dish Network or DirecTV technicians to come out and install a "HD" dish for your home, they aren't really installing a special dish or a special LNBF to allow HD signals of any particular type, they are just installing a dish that can aim at their HD satellite position and a LNBF that can detect and process the polarity and frequency style that emminates from that satellite.
There just isn't any such animal as a "HD" or "4:2:2" capable dish or LNBF, they are all capable of this. You just have to match them to the satellite's style (C Band or Ku, linear or circular, etc).
Therefore, in the FTA world, if you have a dish and a LNBF that can receive the satellite signal, period, that same dish and LNBF can receive the HD and 4:2:2 signals. It is up to your receiver to process the different types (SD vs HD and what not).
The only points which are important here are selecting a dish and a LNBF that are compatible with eachother and with the satellite that is desired. Whether it be C-Band or Ku-Band/Linear or Circular. You can attach nearly any LNBF on any dish and make it work, but there is a component selection that will allow you to make it work better and improve your signal quality which will obviously aid your receivers function of processing the received signal. HD signals may be a little more picky about the signal quality (that is a condition of your receiver mostly) so it may be important to select the dish and LNBF (like a matching set) and align them to obtain the optimum signal quality.
If you are experiencing trouble with any HD or 4:2:2 signals, your trouble is either the actual signal quality level or your receiver's capabilities to process the signal (or the setup in the menus).
