Southwest Antennas Rugged Antenna Solutions and Radio Frequency Accessories for Military Applications

Southwest Antennas specialises in the design of rugged antennas and radio frequency (RF) accessory products for modern warfighters.

We focus on providing solutions across a wide range of radio systems, including dismounted tactical radio, vehicle-based, base stations and unmanned vehicles for military, homeland security, federal and state law enforcement, as well as broadcast video applications.

High-frequency antennae for radio spectrum environments

Focusing on products within the DC-8.4GHz frequency range, Southwest Antennas has developed a full line of antennas in the very high-frequency (VHF), ultra-high frequency (UHF), L, S, and C bands for use worldwide in different licensed and unlicensed radio spectrum environments.

These include antennas for:

  • Applications with existing and upcoming joint tactical radio system (JTRS) military radio waveform standards, including wideband networking waveform (WNW) and soldier radio waveform (SRW)
  • Handheld and manpack radio systems, including body worn antennas
  • Omnidirectional communications and global positioning system (GPS)
  • Unmanned robotics platforms and operator control units
  • Unmanned aerial vehicles (UAV) for integration into aircraft and base station antennas for ground communication
  • Multi-port mesh radio systems: available products include multiple-input and multiple-output (MIMO) / mobile ad-hoc network (MANET) antennas, including omni-directional antennas and directional panel and sector antennas
  • C4ISR systems
  • Battlefield simulation systems
  • Broadband microwave communications (coded orthogonal frequency division multiplexing (COFDM) and MIMO)
  • Electronics warfare and communications intercept (EW and signals intelligence (SIGINT))
  • Covert surveillance applications
  • Mounting systems for rapid antenna deployment

Omnidirectional antennas for military applications

Southwest Antennas has a full range of omnidirectional antennas for military and defence applications, including tactical radio systems, vehicles, unmanned systems, and ground stations.

Options include:

  • Antennas with 2dBi, 4dBi, or 6dBi of peak gain
  • Gooseneck antennas, which can be secured through modular lightweight load-carrying equipment (MOLLE) loops or other tactical clothing if needed. The cylindrical radome provides additional strength, eliminating issues where ‘paddle’ shaped antennas don’t lie flat against the operator’s kit
  • Ultra-flex spring mount base with waterproof seal, which can bend and flex upon impact to protect the mated RF connector from damage
  • Flange mount antennas for helicopter, aircraft, and ground vehicle use
  • Matte black radomes and black chrome RF connectors for low-visibility operations

Antennas for MIMO, MANET, and mesh radio systems

Southwest Antennas is a leading designer of MIMO and MANET antennas for military and federal law enforcement mesh radio systems. These are specially designed for applications involving multi-port tactical radios and mesh network systems.

Improved polarisation and spatial diversity is achieved with slant left / right polarised designs and high-gain directional sector antennas offer beam widths ranging from 56°  to 120°.

Omnidirectional antennas are available with a variety of mount and RF connector options. Directional and omnidirectional body worn antenna solutions have been designed for soldier-worn radio systems.
