Southwest Antennas offers a variety of omni-directional antennas from 0.35 to 8.5 GHz, available with many types of radiating element designs, base options, and RF connectors suited for a variety of different applications. Omni-directional antennas radiate 360° in the horizontal plane around the antenna, and peak gain is usually on the horizon.
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.
- 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.
About Southwest Antennas
Established in 2005 in San Diego, California, US, Southwest Antennas has pioneered the development of many technical advances and design techniques that make our products the preferred choice for many military user groups, RF systems integrators, defence contractors and research organisations. We offer more than 1,200 commercial-off-the-shelf (COTS) antenna and accessory products, including flexible RF coaxial gooseneck assemblies, RF filter modules, diplexers, triplexers, circulators, isolators, and antenna mounting kits.
Antennas with a directional radiating pattern, which send or receive signals from a specific direction as a function of the antenna design. Directional antennas can be designed with higher gain than their omni-directional counterparts but must be more carefully aimed in order to work correctly.
Body Worn Antennas are designed for use with human or animal body worn applications, where the antenna is specifically designed and tuned for optimum performance on the body. The antennas can be placed into or under clothing or against the skin and connected to a radio/transceiver device.
Antennas for use in concealments or covert operations. These antennas are designed specifically to be integrated inside enclosures or other devices and tuned to help mitigate interference from the enclosure.
GPS antennas provide precise global location and timing services to radios or other electronic systems based on signals recieved from orbiting satellites. Active GPS antennas contain additional electronic components and filters which improve antenna performance.
Low Noise Amplifiers (LNAs) are used in receive antenna applications, usually placed between the antenna and the receiver to boost very weak incoming signals. LNAs are often used in microwave communication systems to overcome the noise floor generated by cables and other system components.
Southwest Antennas offers coaxial isolators and circulators for use in RF systems. These devices are used to direct the flow of RF energy through a system in one direction and prevent unwanted damage to sensitive components.
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 / 4G LTE and massive MIMO system that make up a large part of our modern communication infrastructure.
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 across many types of terrain and operating conditions.
