Functional Specification for

Universal/Multi Band/ Dual
Polarized Programmable LNB

The Multi Band Programmable LNB is designed for use anywhere in the world with Ku Band Satellite. Ka Band is optional.

The Multi Band Programmable LNB is a LNB that can be used with any Ku band satellite service in the world.
Customers will no longer be required to change the LNB of the antenna system when they change satellite service or region.

Parameter	Functions
Supported Satellites or Constellations	The Multi Band Programmable LNB will be able to down convert any Ku Band signal from the satellite within the coverage using the Low Band range 10.7GHz to 11.75GHz and 11.45GHz to 12.75GHz in the High Band range. The Multi Band Programmable LNB is suitable in both Circular and Linear polarizations. (Will able to support circular polarized with customized feed only).
