=== [[S band]] LNB ===
[[Image:S-Band_LNB_Bottom_View.jpg|220px|thumb|S-band LNB with written local oscillator frequency]]

Here is an example of an [[S band]] LNB:
* Local oscillator: 1.57&nbsp;GHz
* Frequency: 2.52-2.67&nbsp;GHz
* [[Noise temperature]]: Maximum of 50 [[kelvin]]s (uses kelvin ratings as opposed to dB rating)
* Polarization: Linear

This frequency range of LNB is quite rare as the only [[Satellite television|direct broadcast]] satellites that work with the S-band frequency are [[IndoStar-1]] and [[SES-7|IndoStar-2]], both utilized by Indonesian direct-to-home provider [[MNC Vision]]. S-band was chosen for these satellites because its frequencies efficiently penetrate the atmosphere and provide high-quality transmissions to small-diameter 80&nbsp;cm antennas in regions that experience heavy rainfall such as Indonesia. A similar Ku- or C-band reception performance requires greater transmission power or much larger dish to penetrate the moist atmosphere.
