Detailed Description
This Monoblock LNB is Digital Ready, HDTV approved, latest technology provides the best possible performance. Receives two satellites at four degree spacing. The famous DMS DiSEqC switch is built in allowing you to deliver both signals down one coax without adding move devices in line. 0.3dB noise figure, high stability and high gain insures that you get the best possible picture. Only JSC LNBFs have the ability to give you the best reception.

This is a great FTA LNB.
LNB is A low-noise block converter (LNB, for low-noise block) is the (receiving or downlink) antenna of what is commonly called the parabolic satellite dish commonly used for satellite TV reception. It is functionally equivalent to the dipole antenna used for most other TV reception purposes, although it is actually waveguide based. Whereas the dipole antenna is unable to adapt itself to various polarization planes without being rotated, the LNB can be switched electronically between horizontal and vertical polarization reception. The LNB is usually fixed on or in the satellite dish, for the reasons outlined below. The corresponding component in the uplink transmit link is called a Block upconvert (BUC).
Satellites use comparatively high radio frequencies to transmit their signals.
