Omnidirectional antennas radiate maximum power uniformly in all directions, in the horizontal plane. These center-fed collinear antennas ensure consistent gain and impedance across the frequency band for a wide variety of applications, including land mobile radio services from 806-960 MHz Numeko Tech has been supplying Omni antennas since the early days of radio communication. The portfolio includes antennas for extensive rural coverage.
Remote Tilt System
Introducing the Optimizer RT from industry leader Radio Frequency Systems (RFS). Antenna tilt adjustment from either tower base or network management center is now an operational reality, thanks to RFS’s latest generation remote tilt technology - the Optimizer RT Antenna Control system.
The Optimizer RT antenna control system permits accurate antenna tilt operations to be conducted - without installers or crane equipment - either from tower base or the network management center. Easily interfaced with existing Network Management Software, the RFS Optimizer RT provides the ultimate in real-time network optimization.
Other Directional Antennas
The YAGI antennas series available in various gains for 406 - 512MHz and 806 - 960MHz bands
The APV series with field adjustable horizontal beam width designed to fill multiple horizontal pattern coverage requirements. This flexibility allows custom tailoring of cell coverage and avoids antenna replacement as sectors change. The reflector can be easily adjusted and provides coverage in six different settings; 46°, 60°, 78°, 90°, 105°, and 110° horizontal beam width.
The AH series specially design for tunnel coverage thanks to the circular polarization. Antennas are available for cellular networks in low band, high band and dual band applications.
Optimizer CELlite Antennas: Rugged construction and lightweight design
The best of both worlds: Introducing RFS antennas featuring CELlite and Optimizer technologies for the rapid rollout of wireless networks in densely populated regions. These antennas are manufactured with premium quality materials to ensure superior performance. The microstripline feed system consists of monolithic aluminum construction allowing for:
- Minimal welded joints to reduce the possibility of intermodulation problems
- Minimal power losses to increase the antenna gain
- Perfect production reliability and repeatability
Each antenna features lightweight, one-piece panel construction for ease of installation, reducing handling cost. All aluminum components are treated to minimize corrosion, assuring reliable operation in icing, salt air and rain conditions. These antennas support all services between 806MHz and 960MHz. They are ideal for CDMA applications and GSM900 network coverage and optimization.
- Rugged CELlite construction – Ensures high reliability
- Low PIM – Eliminates system down-time, provides excellent call quality and reduces the number of dropped calls
- Dual polarized – Optimizes RX performance
- Excellent upper sidelobe suppression – Allows strong mechanical tilt
- High gain – Provides better coverage
- Wideband frequency performance – Enables future growth and increases flexibility
Ultra-Broadband Antennas: Ultra-flexible LTE spectrum support
RFS Ultra-Broadband Antennas dramatically simplify antenna requirements by supporting the full range of potential LTE frequencies on a single platform. Ready for LTE testing today, they eliminate the need to replace or add antennas as operator’s trial and deploy LTE services at different frequencies.
These antennas bring tremendous flexibility to operators with 2G, 3G, PCS, AWS, GSM1800 and mobile TV networks, enabling them to activate LTE in any frequency band, using Software-Defined Radio (SDR) – without changing the antenna. The antennas are thus ideal for meeting rebanding and refarming requirements in the 1710-2700 MHz range.
Available in dual polarization or sideby-side quad polarization versions, the antennas feature RFS premium performance: high gain, high upper sidelobe suppression and performance stability across frequencies. They also provide easy adjustments, optional remote tilt, and a low-profi le design to minimize visual impact.
The side-by-side version gives operators increased fl exibility to support multiple technologies and seamlessly add capacity – all under a single radome. During LTE rollout, operators will benefi t from Multiple Input Multiple Output (MIMO), beamforming and 4-way receive (Rx) diversity.
