K-based Sigma Wireless Technology has produced world-class antenna solutions for numerous RF technolo-


gies for over 40 years in more than 40 countries. T ey can be found in countless, diverse appli- cations, including emergency response, trans- portation, telemetry, GPS timing, WiMAX, Wi-Fi, Tetra infrastructure, cellular infrastruc- ture, agriculture, SCADA, utilities, oil and gas, indoor coverage, taxis, ports, other private and public VHF-UHF networks and more. Sigma’s product range boasts globally re-


nowned product brands such as CATC, WDTC, RDTC, SWAN, LP, LP3, LHA and MHA. Its SWIFT range of antennas is recog- nized as a world-leading product for the criti- cal Tetra networks used by emergency response and government agencies, where reliability and product excellence are paramount. Over the decades, the company has seen sev- eral changes of ownership, which at times pro-


vided its own challenges. But in 2008 Sigma returned to being privately owned, with a clear focus and strategy for growth. “Our success is directly related to the success of our custom- ers”, explains CEO Gordon Campbell. “We are passionate about understanding the market and building long-term relationships, helping our customers grow successful businesses by consist- ently providing the world’s foremost antenna so- lutions at competitive prices, delivered on time.” Recognized as a market leader in low-profi le


antennas for bus, rail, tram and metro appli- cations, Sigma provides solutions for VHF, UHF, Tetra, GSM, UMTS, GPS and WLAN technologies in single or multi-band antennas. Renowned for their durability, electrical per- formance, functionality and ease of installation, these antennas are deployed around the world. Sigma’s portfolio includes high-quality in-


building and microcell antennas for almost eve- ry major RF technology and application in sin-


When it comes to choosing a quality radiocommunications antenna for performance and durability, Sigma has the products and the heritage to deliver


gle band, wideband and multi-band formats. Great consideration has been given to aesthet- ics, in producing well designed, low-profi le di- rectional and omni-directional antennas. Production manager David Macmillan adds:


“Quality, innovation and integrity are at the heart of our business. A Sigma antenna not only performs superbly but withstands the de- mands of harsh environments.” A close relationship and distribution agree-


ment with PCTEL enables Sigma to off er complementary products, including Bluewave high endurance yagis, high-performance omnis, WiMAX cross-polarized panels and GPS timing, smart and embedded antennas that boast some of the industry’s lowest noise fi gures, ensuring clear GPS signals in less than ideal conditions. • Sigma CEO Gordon Campbell is attending
