Typical antenna sizes on C-band-capable systems range from 6 to 12 feet (1.8 to 3.5 meters) on consumer satellite dishes, although larger ones also can be used. For satellite communications, the microwave frequencies of the C band perform better under adverse weather conditions in comparison with the K u band (11.2–14.5 GHz ), microwave ...
This great decrease of dish size also allowed satellite dishes to be installed on vehicles. [10] Dishes this size are still in use today. Television stations, however, still prefer to transmit their signals on the C-band analog with large dishes due to the fact that C-band signals are less prone to rain fade than K u band signals. [11]
[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.

A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [1] is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s to 16 Mbit/s.
The C-band antennas are generally large, from 2.4–3.6 m (7.9–11.8 ft) in dish diameter. The Ku-band antennas are smaller, from 1–1.5 m (3.3–4.9 ft) in dish diameter. The BDE most commonly consists of one electronic rack containing the following components: an iDirect modem , the SEVSAT global satellite switching unit, a DAC , Cisco ...
