The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). [1] However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. [2]
In a C-band antenna setup, the transmission frequencies are typically 3.7–4.2 GHz. By using a local oscillator frequency of 5.150 GHz the IF will be 950–1,450 MHz which is, again, in the receiver's IF tuning range.
[citation needed] As of 2009, there are 23 C-band satellites and 38 K u /K a band satellites. [17] There were over 150 channels for people who want to receive subscription channels on a C-band dish via Motorola's 4DTV equipment via two vendors Satellite Receivers Ltd (SRL) and Skyvision Archived January 13, 2011, at the Wayback Machine.

The term bandstacked applies to an antenna or satellite feedhorn (LNBF) that is designed to operate on two or more bands of frequencies. Usually, a portion of the radio frequency spectrum that has been divided into a low band and a high band. [citation needed] This example is for a C Band LNBF that operates with two different local oscillator ...
C band may refer to: C band (IEEE), a radio frequency band from 4 to 8 GHz; C band (infrared), an infrared band from 1530 to 1565 nm (roughly 200 THz)

VK3IL - Multiband end-fed 80-10m antenna - NEC2 model file of a "MyAntennas EFHW-8010" multi-band antenna. Other retail books (such as The ARRL Antenna Book, Marcel De Canck's Advanced Antenna Modeling, and others) also include antenna model files. Most free or retail NEC software packages include an 'example' folder containing antenna model files.
