Thus, smaller dishes can be used to achieve the same distance as C-Band and the Ku-Band radio transmitter also requires less power. Moreover, Ku-Band is characterized by its high powered signals compared to C-Band. This solves the problem of interfering with terrestrial microwave backhaul links. Unlike C-Band, Ku-Band frequencies are dedicated for satellite communication only. Thus, C-Band requires more expensive equipment which list generally larger and heavier therefore more expensive to freight to and from site compared to Ku-Band (more Capital Expenditure “CAPEX” and higher freight costs).

2.4, 3 or 3.7 meters in diameter), so that they can be received from the satellite. However, these signals need larger dish size ( e.g. Moreover, these less focused signals can provide wider range of coverage. The attenuation on C-Band signal due to rain fading ranges from 0.4 dB to 1 dB only. Less focused signals means that these signals are less affected by rain (a phenomenon known as rain fade of satellite signals). This is due to the longer wavelength in C-Band. On the other hand, signals in C-Band are less focused compared to higher satellite frequencies such as Ku-Band. Thus, ITU started to define new frequency bands as Ku-Band. This resulted in a great interference problem between C-Band and terrestrial backhauling links.

Transportable antennas are manufactured with many and various options. The maximum recommended towing speed is 55 mph. On the 5 meter antenna the top and bottom portions of the reflector are hinged to fold back to the center of the reflector during transit. The trailer is equipped with three, crank operated feet for leveling and stability. The 2.4, 3 and 3.66 meter antennas may be operated with wind gusts of up to 60 mph the 5 meter antenna is rated for wind gusts of up to 40 mph in the standard configuration.ĭepending on reflector size, the antenna base is mounted on a single or dual axle, 8 foot wide trailer with a standard ball hitch. In the US, the range is set from 10 to 65 degrees. The azimuth base provides 360° rotation, the elevation is continually adjustable over a 55 degree range from 5 to 90 degrees. The antennas consist of a composite material fiberglass reflector mounted on an elevation over azimuth base. In the Ku band the uplink and downlink frequencies are 14 and 12 GHz, respectively. In the C band the uplink frequency is 6 GHz, the downlink frequency is 4 GHz. The antennas may be used for uplinks or downlinks in the C, Ku or other bands of operation.
