The intermediate frequency band is much wider than in a conventional LNB, as the high and low band are not split up. Wideband LNB signals can be accepted by new wideband tuners, and by new SCR systems (e.g., Inverto/Fuba, [ 10 ] Unitron, [ 11 ] Optel, [ 12 ] GT-Sat/Astro), with or without optical transmission.
