===Wideband LNB=== ASTRA Universal Wideband LNBs with an oscillator frequency of 10.40 or 10.41 GHz are entering the market. 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,<ref>{{Cite web | url=http://www.inverto.tv/products/product.php?section=49&id=328&cat=124 | title=Inverto - IDLU-UWT110-CUO1O-32P - | website=www.inverto.tv | access-date=2016-07-01 | archive-date=2016-08-20 | archive-url=https://web.archive.org/web/20160820180050/http://www.inverto.tv/products/product.php?section=49&id=328&cat=124 | url-status=dead }}</ref> Unitron,<ref>{{Cite web | url=http://www.unitrongroup.com/upl/document/Catalogue%202016-2017-ENG.pdf | title=Unitron catalog | access-date=2016-07-01 | archive-date=2016-09-19 | archive-url=https://web.archive.org/web/20160919040740/http://www.unitrongroup.com/upl/document/Catalogue%202016-2017-ENG.pdf | url-status=live }}</ref> Optel,<ref>{{Cite web | url=http://www.optelit.com/satellite&terrestrial.asp | title=Optel | website=www.optelit.com | access-date=2016-07-01 | archive-date=2016-08-06 | archive-url=https://web.archive.org/web/20160806000529/http://www.optelit.com/satellite%26terrestrial.asp | url-status=live }}</ref> GT-Sat/Astro), with or without optical transmission.

The basic model has only 2 connections and presumably has a local oscillator of 10.41 GHz with an intermediate frequency of 290β2340 MHz from an input of 10.7β12.75 GHz. This LNB seems to be the same as Unitron's ASTRA Universal Wideband LNB.<ref>LNB http://www.unitrongroup.com/en/news-events/unitrongroup-introduces-wideband-satellite-product-family.html {{Webarchive|url=https://web.archive.org/web/20200806215452/https://unitrongroup.com/en/news-events/unitrongroup-introduces-wideband-satellite-product-family.html |date=2020-08-06 }}</ref> Two cables minimum are needed to access all channels. In the Sky Q box, multiple tuners can select multiple channels, more than the usual two for dual coax systems. This type of LNB is incompatible with the more common Astra Universal LNB used in the UK meaning the LNB is changed during upgrade. There is a model of the LNB with 6 connections, 2 for Sky Q and 4 Astra Universal LNB for users with multiple legacy systems such as Freesat in addition to Sky Q. In cases where only a single cable is possible, such as apartment blocks, Sky Q compatible multiswitches can be used, which instead use BSkyB SCR.<ref>{{Cite web |url=http://www.unitrongroup.com/download.php?lang=en&id=657 |title=Unitron Group β’ Your dedicated partner for customize IP and RF solutions |access-date=2016-05-14 |archive-date=2016-08-10 |archive-url=https://web.archive.org/web/20160810170148/http://www.unitrongroup.com/download.php?lang=en&id=657 |url-status=live }}</ref>
