1 to 2GHz Prime Focus Parabolic Antenna

Prime Focus Parabolic Antenna 1-2GHz for Satellite Communication and Radar

This product is a professional Parabolic Antenna with a prime focus front feed design. The antenna operates from 1GHz to 2GHz in the L band and features a 2 meter aperture reflector. As a Prime Focus Parabolic Antenna, the feed antenna is positioned at the focal point in front of the parabolic reflector. This classic configuration provides high gain, strong directivity, long distance transmission capability, narrow beamwidth, and excellent focusing ability. The antenna offers dual circular polarization for compatibility with various satellite and radar systems. The structure is simple, making installation and alignment straightforward. The antenna features an SMA K type connector and is built with durable materials for long term outdoor use.

This prime focus parabolic antenna delivers excellent electrical performance across its operating range from 1GHz to 2GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 2.0, which shows good impedance matching. The gain is 23dB or higher, providing very strong signal strength for long distance communication and radar tasks. The front to back ratio is 20dB or better, ensuring that signals coming from behind the antenna are effectively rejected. The axial ratio is 3.0dB or better, ensuring good circular polarization purity. The dual circular polarization allows the antenna to work with both left hand and right hand circular polarized signals. The power handling capability is suitable for moderate power transmission applications. The mounting system allows manual adjustment of both azimuth from 0 to 360 degrees and elevation from -20 to 90 degrees, enabling precise pointing toward the target satellite or remote station.

One clear strength of this Prime Focus Parabolic Antenna is its versatility across many high power long distance applications. It is widely used in satellite communication earth stations, broadcast television and radio transmission and reception, microwave long distance point to point communication links, weather remote sensing and monitoring, aerospace telemetry tracking and control, defense and military systems, field industrial and emergency communication, as well as educational and scientific research. The high gain of 23dB means this antenna can transmit and receive signals over very long distances with reliable performance. The narrow beamwidth allows for precise pointing, which reduces interference from other sources. The dual circular polarization capability is especially valuable for satellite communication where circular polarization is standard.

In practical use, this Prime Focus Parabolic Antenna handles professional long distance communication tasks very well. For satellite communication earth stations, it serves as a reliable ground terminal antenna for L band transceivers. The dual circular polarization matches satellite signals exactly, maximizing link budget. The manual azimuth and elevation adjustments allow field alignment without special tools. For radar systems, the high gain and narrow beamwidth provide accurate target detection and tracking. For broadcast applications, the antenna delivers strong signals over wide coverage areas or receives distant broadcast signals clearly. The 2 meter aperture provides good balance between gain and physical size, making installation practical for many sites. The SMA K connector provides a precision connection point. It stands as a solid example of how a well designed Prime Focus Parabolic Antenna can meet the demanding needs of satellite communication, radar, and broadcast applications at 1-2GHz.
