Southwest Antennas offers an entire line of STC flange mount antennas that can be mounted to helicopters, propeller driven aircraft, and aerostats for air-to-ground communication.

Integrated Bandpass Filters help eliminate out of band co-located radio interference without adding additional external components to radios or antennas

Southwest Antennas has released the first in their new product line of filtered omni-directional antennas, giving users additional operational flexibility in radio placement while helping to attenuate disruptive frequencies outside of their operational frequency band. This is particularly important for users who will be operating in close proximity to high-powered transmitters, such as military radio systems.

Our new whitepaper Understanding the Basics of MIMO Communication Technology is now available to read and download from the Southwest Antennas website. Originally published by Microwave Journal in December 2016, we're pleased to share this white paper with our audience as well. This whitepaper covers the basics of MIMO radio and antenna technology from a general non-technical standpoint.

New S and C-Band Antennas Add Type-N(m) RF Connector Option

Small, thin antennas are easy to integrate into other devices and are available in multiple bands for commercial, government, military, and law enforcement applications


Southwest Antennas is pleased to announce the addition of five new antenna products to its extensive concealment antenna product line, giving users additional antenna integration options for 900 MHz ISM, L, S, and C band application needs.

1.4 - 1.7 GHz and 1.7 - 2.5 GHz frequency options provide operational selections for international applications, US federal law enforcement, or license-free ISM band use


Several new antenna options are now available for 1.0 - 1.5 GHz L-Band, ideal for international or federal law enforcement / military use.

Omni Half Wave Dipole Antenna, 1.0 - 1.5 GHz, 2.15 dBi

Our small 1 – 1.5 GHz half wave dipole antennas are only 7” long and 0.56" in diameter, making them ideal for mounting on aircraft, helicopters, or vehicles. A Type-N(f) RF connector is located under the flight-rated STC flange, which features lock-wired screws for additional safety.


Since their introduction, our Ultra-Flex dipole omni antennas have become a popular option for extending range and performance of radio systems, particularly with MIMO and MANET applications.

Southwest Antennas manufactures a wide variety of circularly polarized bifilar omni antennas for applications such as ground to air communication and live video transmission.
