Other MIMO Antenna Solutions

Our Ultra-Flex omni antennas and Integrated Gooseneck omni antennas are both great choices for MIMO systems as well, giving operators an affordable choice for high-performance, rugged antennas.


Our low-profile 2.4 - 2.5 GHz panel antenna is designed specifically for 802.11g/n Wi-Fi and unlicensed ISM band applications. The small form factor design allows the antenna to be easily integrated with radio systems for rapid deployment ad-hoc networks for both commercial and government applications. Included mounting holes also allow for long-term installation within buildings or other structures. The sealed Kydex radome is UV stable and weatherproof, making the antenna suitable for both outdoor or indoor use, and is MIL-STD 810 drop test compliant.

Part # 1011-005 - white radome
Part # 1011-006 - black radome


RF Coaxial Gooseneck Assemblies allow for flexible mounting for antennas on radios or other products, giving users the ability to bend the gooseneck over 90 degrees to optimize antenna transmit or receive positions and help minimize cosite interference. RF Coaxial Goosenecks from Southwest Antennas come in a range of lengths, diameters, and RF Connector options and can be customized to maximize compatibility across all radio platforms and antennas.

We're pleased to introduce our new small form factor “Turbo Cloverleaf” family of circularly polarized (CP) Omni antennas in 1.98 - 2.2 GHz and 2.3 - 2.5 GHz frequencies.

These new and innovative antenna products deliver substantial increases in high data rate throughput and signal-to-noise ratio (SNR) in a very compact, rugged radome that measures two inches or less on all sides. Each antenna in the new family of products also features an integrated three inch RF coaxial gooseneck assembly with ruggedized non-rotating RF connector options that allows for flexible antenna mounting and positioning with other closely located equipment or co-located antennas.

This is the world’s smallest cloverleaf style antenna offering robust performance with modern radio systems that are increasingly seeing operation in the wireless broadcast TV / wireless video and live sports markets, UAV / drone video systems, vehicle-mounted radios, and tactical law enforcement and military radios that are utilizing MIMO/MANET system architectures for improved video, voice, and data transmission.


Southwest Antennas provides quarter wave monopole antenna solutions to many radio manufacturers, defense companies, and commercial clients for use on handheld and body worn radio systems.

We design and manufacture several types of monopole antennas:

50 Ohm quarter wave narrow band monopoles
50 Ohm quarter wave wide band monopoles with matching network integrated into the base of antenna
Non-50 Ohm monopole antennas that can be matched with components inside radio system

Monopole antennas are single conductor antennas which require connection to a ground plane to operate, unlike dipole antennas which contain two conductors and are generally ground plane independent. For example, with a handheld radio, the radio itself acts as a ground plane for the monopole antenna.

To achieve desired bandwidth monopole antennas are often designed to include matching network components, which ensure the antenna achieves desired band coverage for its application. However, the ability to change the matching network allows for unique applications for non-50 Ohm antennas.


Magnetic Mounting Kits are an excellent way to temporarily secure an antenna to a vehicle or any magnetic surface. We offer out Magnetic Mounting Kits with a variety of RF connectors, RF cable lengths, and frequency coverage options.

Magnetic Mounting Kits, offered with and without integrated RF cables.
