iDirect DiSEqC 22 kHz Universal Ku-Band PLL LNB (NJR2842L)

iDirect’s DiSEqC 22 kHz Universal Ku-band PLL LNBs are highly stable low-noise block converters with superior phase noise performance. Compatible for use with the Evolution platform.

The iDirect portfolio of advanced BUCs and LNBs is specifically tailored around the capabilities of iNFINITI® and Evolution® satellite routers, creating synergies that deliver increased flexibility, efficiency, and convenience through genuine innovations in ODU design and manufacturing.


BUCs feature standard plus extended Ku-band uplink range, covering 13.75 – 14.5 GHz contiguously. PLL LNBs can be used for all three Ku-band downlink sub-bands of Euro Low, Americas & Euro High (10.7 - 12.75 GHz), switched across two L-band ranges through DiSEqC (22KHz tone) control by an Evolution remote or user selected via a mechanical switch.


iDirect’s ODU products are more power efficient than alternative products, which reduces power consumption and carbon emissions, as well as easing deployments of remotes supplied by solar and other restricted power sources.


Improved power efficiency results in smaller heat sinks to cool ODU electronics. iDirect’s 3W Universal BUC occupies only a fraction of the volume of equivalent products and weighs just 350g. This results in less weight and wind-loading on antenna feed-arms and means that low-cost lightweight ‘Class 1’ antennas can be used with greater confidence.
