C Band
C Band is the original frequency allocation for communications satellites.
C-Band uses 3.7-4.2GHz for downlink and 5.925-6.425Ghz for uplink.
The lower frequencies that C Band uses perform better under adverse weather conditions than the Ku band or Ka band frequencies.
C Band Variants
Slight C Band frequency variations are approved for use in various parts of the world.
| Band | TX Frequency | RX Frequency |
|---|---|---|
| Extended C Band | 5.850 – 6.425 GHz | 3.625 – 4.200 GHz |
| Super Extended C-Band | 5.850 – 6.725 GHz | 3.400 – 4.200 GHz |
| INSAT C-Band | 6.725 – 7.025 GHz | 4.500 – 4.800 GHz |
| Palapa C-Band | 6.425 – 6.725 GHz | 3.400 – 3.700 GHz |
| Russian C-Band | 5.975 – 6.475 GHz | 3.650 – 4.150 GHz |
| LMI C-Band | 5.7250 – 6.025 GHz | 3.700 – 4.000 GHz |
C Band Dishes
C Band requires the use of a large dish, usually 6′ across. C Band dishes vary, between 3′ and 9′ across, depending upon signal strength.
Because C Band dishes are so much larger than Ku and Ka Band dishes, a C Band dish is sometimes referred to in friendly jest as a BUD (Big Ugly Dish).

- Ka Band
The Ka band uplink uses frequencies between 27.5GHz and 31Ghz and the downlink uses frequencies between 18.3 and 18.8Ghz and between 19.7 and 20.2Ghz. The Ka band is branch of the K band from the electromagnetic spectrum. The term “Ka-band” is from Kurz-above, which originates from the German phrase “kurz” implying short. Ka band dishes [...]...
- Ku Band
The Ku band (Kurtz-under band) is primarily used for satellite communications, particularly for editing and broadcasting satellite television. This band is split into multiple segments broken down into geographical regions, as the ITU (International Telecommunication Union) determines. The Ku band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from [...]...
- L band
L band is a fequency range between 390MHz and 1.55GHz which is used for satellite communications and for terrestrial communications between satellite equipment. The high frequencies utilized by C band, Ku band, and Ka band would suffer from high signal loss when transported over a copper coax cable such as an Intra-Facility Link. An LNB [...]...
- DirecTV Satellite Dishes
DirecTV Phase I Satellite Dish The DirecTV Phase I Satellite Dish was the original DirecTV dish. This is an 18" satellite dish with one LNB. This dish can only receive signal from DirecTV satellites at 101 degrees. DirecTV Phase II Satellite Dish DirecTV introduced the Phase II Satellite Dish in 1998. The Phase II dish [...]...
- S Band
S band is a frequency range from approximately 2 to 4 GHz. S band is used for Digital Audio Radio Satellite (DARS) satellite radio systems such as Sirius XM Satellite Radio. Sirius XM uses frequencies between 2,320.00 and 2,332.50 MHz, and also between 2,332.50 and 2,345.00 MHz. S band is also used by many weather, [...]...
