Ideal for HD video and high speed data transmission and reception from mobile platforms and offers great improvements to spatial diversity and spatial streaming in MIMO radio systems.
Southwest Antennas is pleased to introduce its 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 less than two inches on any side.
Each antenna in the new family of products also features an integrated 3” 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.
The new Turbo Cloverleaf antennas were designed with radio users in mind who are in need of the performance that only a Cloverleaf style CP Omni antenna can offer, but in a new compact form factor.
The resulting design delivers 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.
“Typical L/S licensed band and 2.4GHz ISM band Cloverleaf antennas currently available on the market have many inherent design flaws that make them ineffective at best for unmanned systems applications and applications requiring two or more co-located antennas” said Benjamin Culver, President, Southwest Antennas.
The design and size of this new product line makes it a great options for various applications.
“First, the Cloverleaf antennas currently available on the market do not typically have a ruggedized Radome or any Radome at all and they just use exposed wiring to create the antenna cloverleaf radiating element structure that is covered with plastisol or similar insulated coating, leaving the antenna easily susceptible to damage. Second, these antennas measure well over 6” in outside diameter making them impractical for installation on a UAV or drone platform. Third, they have poor and improper impedance matching at the antenna feed point and finally they have poor radiation pattern control over frequency due to inadequate RF choking on the antenna’s cable feed.
“The new Southwest Antennas Turbo Cloverleaf antenna design solves all of these challenging design problems by the implementation of the proprietary new Southwest Antennas design approach which reduces the size of the cloverleaf antenna drastically by over 3X in outside diameter without adversely affecting antenna gain or efficiency. The new design uses SMT components inside the Radome located on the antenna element to tune the antenna performance perfectly right at the antenna feedpoint which is a critical factor in the design of high performance cloverleaf antennas. Other proprietary design techniques are used to maintain excellent radiation pattern control over the entire operational frequency band. In short, Southwest Antennas has solved some huge antenna industry problems with the new Turbo Cloverleaf design and we expect this new design to receive industry wide adoption in a large number of diverse applications where status quo Cloverleaf antenna products will just not meet the system requirements”.
The proprietary Southwest Antennas Turbo Cloverleaf antenna designs offer over 40dB of isolation between two co-located antennas with opposite CP polarizations which is a significant improvement over two co-located vertical or opposite slant polarized antennas. This new design has shown over 50% improvement in data rate throughputs and over 30% improvements in SNR.
These exciting new antenna products are now available for immediate purchase in both Right Hand and Left Hand circular polarizations.

About Southwest Antennas
Southwest Antennas specializes in the design and manufacture of rugged, high-performance RF and Microwave antennas, accessory products, and customized antenna solutions built for today’s demanding communication environments. Founded in 2005 and headquartered in San Diego, California, Southwest Antennas offers over 1,000 standard products for broadcast video, military / defense, law enforcement, homeland security, surveillance, aerospace, oil and gas, and M2M markets.
The StreamCaster 4200 (SC4200) radio by Silvus Technologies was recently selected by MILREM, a manufacturer of Unmanned Ground Vehicles (UGV) based in Estonia. MILREM will integrate the SC4200 onto the Tracked Hybrid Modular Infantry System (THeMIS) platform.
THeMIS UGV is an intelligence, surveillance and reconnaissance (ISR) platform. It assists with target acquisition, logistics support, and other missions.
The SC4200 serves as the datalink, providing wireless command/control and video. It pairs with high performance antennas to allow the THeMIS to drive extended ranges, and push video and data communication farther than before.
“Silvus is offering rugged and high quality MIMO radios which have proven to provide reliable wireless video and data communication over extended range,” said Rivo Opik, MILREM’s Chief Engineer. “The technical support and guidance from the Silvus team has been quick and very effective.”
SC4200 2x2 MIMO radio features transmit beamforming which nearly doubles the signal range. The ability to significantly extend range is why MILREM choose the SC4200 for the THeMIS. Companies purchasing the THeMIS can control, one, two or an entire fleet of these UGVs. In addition, users can monitor what is happening using a real-time, live HD-video feed from the Silvus radios.
