Southwest Antennas Releases New C-Band Omni-Directional Antenna with Integrated Bandpass Filter

Southwest Antennas has released a new addition to our expanding line of antenna products that include integrated filters to help improve the performance of attached radio systems in radio-frequency (RF) congested environments such as cities or other urban areas, military bases, government facilities, and more.

Part # 1085-220 has a four-section collinear element design, which provides 6dBi of peak gain. The antenna features a 4.4GHz-5.0GHz operating frequency, with an internal bandpass filter to help mitigate interference from co-located radios or other transmissions outside of the antenna’s operational frequency range. By integrating the filter inside of the antenna the user doesn’t need to remember an additional system component or worry about powering any additional devices.

The 4.4GHz-5.0GHz operational frequency band coverage is ideal for DoD, federal law enforcement, homeland security, and NATO-licensed band applications.

The antenna’s weatherproof sealed spring base can bend +/- 45 degrees, providing protection against damage to the mated RF connector and radio system if the antenna is struck by another object. The weatherproof seal protects the spring against rain, dust, mud, sand, or other debris that could foul the spring or impact antenna performance.

Utilising high-quality antennas is a cost-effective way to upgrade the performance of an existing radio systems for better RF link margin and higher data/video throughput...
Radio systems utilising MIMO (multiple-in, multiple-out) technology have become increasingly common over the past several decades, with notable examples being Wi-Fi networks and cellular 3G...
