Omni-Directional Antennas for RF Congested Environments

Enhance your radio's operational capabilities in RF congested environments and help mitigate co-site interference, receiver desense, and other related system-level issues with our line of omni-directional antennas with integrated RF filters.

Southwest Antennas’ line of filtered omni-directional antennas give users additional operational flexibility in radio placement while helping to attenuate disruptive frequencies outside of the antenna’s operational frequency band. This is particularly important for radio systems that will be operating in close proximity to high-powered transmitters or congested RF environments where co-site interference is a concern, such as urban areas, military bases, government facilities, and more.

An RF filter is securely fitted inside of the antenna radome and integrated directly with other RF components, ensuring survivability during harsh field use. Custom electronics inside of the antenna assures optimal performance across the antenna’s entire operating frequency range.

By integrating the filter within the antenna installations are simplified through a reduction in parts, and additional insertion loss from multiple RF connector transitions is reduced.

Multiple antenna bases and RF connector options are available, including flexible RF coaxial goosenecks or spring base options.
