Transportable Antennas

2.4, 3, 3.66 and 5 meter for C, Ku and Special Band Operation

Return to AFC Home Page

AFC's transportable antennas offer superior performance for a variety of different applications. The antennas may be used for uplinks or downlinks in the C, Ku or other bands of operation. In the C band the uplink frequency is 6 GHz, the downlink frequency is 4 GHz. In the Ku band the uplink and downlink frequencies are 14 and 12 GHz, respectively.

The antennas consist of a composite material fiberglass reflector mounted on an elevation over azimuth base. The azimuth base provides 360° rotation, the elevation is continually adjustable over a 55 degree range from 5 to 90 degrees. In the US, the range is set from 10 to 65 degrees.

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.

Depending on reflector size, the antenna base is mounted on a single or dual axle, 8 foot wide trailer with a standard ball hitch. The trailer is equipped with three, crank operated feet for leveling and stability. 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 maximum recommended towing speed is 55 mph.

Transportable antennas are manufactured with many and various options. Options include foldable 3 piece reflectors for 2.4, 3, 3.7 and 5 meters diameter quick deployable missions, shelters, anti-ice, feed systems, hand-crank or motorized Az/El pedestals. The table, below, shows AFC's transportable antenna operating specifications.
