Product Focus – Base Antennas
Base antenna withstands harsh conditions
Antenex‘s family of fiberglass-enclosed base antennas for the 2.4GHz band offers 6dBd gain and has a VSWR of 2.0:1 from 2.4GHz to 2.48GHz. The antennas can be mounted outdoors in harsh weather conditions. The FG series of antennas have the same outer shell design used in the company’s lower-frequency fiberglass-enclosed base station family. A high-gloss, heavy-wall fiberglass radome, a finish ground, schedule 80, a gold anodized aluminum sleeve for mounting and a gold anodized aluminum cap complete the durable yet sleek look. On the inside, a rigid, highly consistent and low-loss PC board trace is used to construct the collinear radiator. The product also features a nickel-plated brass N female connector in the base for feed-line connection.
Antenna operates with integral ground plane
The ANT150F2 from Telewave is a compact, omnidirectional collinear antenna with an integral ground plane, which covers 148MHz-700MHz. The antenna is enclosed in a rugged structural composite radome, with a total height of only 60″. The antenna’s gain is 2.5dB minimum, with a nominal power rating of 500W. The vertical beamwidth is 30°, allowing RF coverage of low-lying areas such as valleys and canyons. This antenna is useful for replacement of old VHF ground-plane or “J-hook” type antennas. N female or optional 7-16 DIN female connectors are available. The ANT750F2 is a similar antenna that covers the 734MHz-806MHz range. Shadowing and multipath common in the upper UHF bands can be greatly reduced with this antenna. The model ANT750Y5-WR is a heavy-duty directional yagi antenna that covers 734MHz-806MHz. The gain is 5dBd minimum, with a nominal power rating of 500W. The antenna is coated with Txylan material to eliminate damage from corrosion or abrasion. The active element connection and feedline are sealed inside the antenna boom.
Antenna delivers high-gain performance
Corner-style antennas from Antenna Factor are available in models covering frequencies from 800MHz to 2.4GHz. The antennas are designed for long distance, directional communications and enhance the performance of RF links. All models feature high gain, a wide beamwidth, greater-than 70MHz bandwidth and 25dB front-to-back ratio. The antennas are constructed to withstand the stress of long-term use and are designed for 50V system matches with a maximum input of 100W.
Antenna provides flexibility
The XtremeWave MSO24014PTNF all-terrain sectorized omnidirectional antenna from Maxrad is designed to provide pattern shaping flexibility to wireless Internet network planners by applying electrical and mechanical technology to a single antenna model. This antenna allows individual sector adjustments of as much as 15° of uptilt or downtilt, permitting system planners to contour their coverage area according to the geographic conditions of the territory. For applications with specific coverage demands, the antenna offers more than 10 azimuth pattern options, optimized to address varying coverage, cost control and tower space limitations.
Omni-directional antenna for 5GHz
Mobile Mark’s omnidirectional site antennas for 5.2GHz and 5.8GHz are available in 6dBi and 9dBi gain configurations. These high-frequency antennas are designed for new microwave systems, including UNII networking. The design accommodates high-speed wideband performance. The antennas provide a uniform omni pattern and are enclosed in a black polycarbonate radome that measures 18″ long and 1″ wide. The antenna terminates with a female N connector and comes with all hardware needed to mount it to a pole, ceiling or surface/offset mount.
Antennas combine with subscriber units
Radiall/Larsen Antenna Technologies’ line of base station antennas, when combined with existing subscriber unit antennas, are useful for complete broadband wireless needs. The product line includes systems at ISM 2.4GHz and 5.8GHz and UNII 5.2GHz-5.8GHz bands. The product types include solid parabolics, grid parabolics, field adjustable sectors, fixed sectors and one new yagi.
Base station antenna features adjustable tilt
The Optimizer Plus AXE199014 adjustable downtilt antenna from Radio Frequency Systems features polarization diversity in addition to the continuously adjustable dial-turn electrical tilt process. The adjustable electrical tilt provides the system operator flexibility for any time a new value of electrical tilt is required. The operator simply turns the dial on the back of the antenna. Polarization diversity is suited to dense urban areas. This type of antenna can result in lower site costs. Fewer antennas are required to cover a given area, which simplifies mounting and allows the use of towers without platforms. This model is used by PCS systems operators in the 1,850MHz-1,990MHz band.
High-gain yagi supports SCADA, RPU apps
The SAM-460 from Samco Antennas is a small, lightweight antenna built for the 400MHz-512MHz range. It is designed for use in a variety of situations, including SCADA and RPU applications. This antenna is hand-tuned for optimum performance in the field. It is suited for permanent applications where stealth is a factor. Features include a forward gain of 10dB, impedance of 50V, type N female termination and a VSWR of 1.5 to 1 or less. Polarization is vertical or horizontal.
Antennas collocate multiple services
The dual-frequency, dual-polar base station antennas from Alan Dick & Company cover the 824MHz-894MHz and 1,850MHz-1,990MHz frequencies simultaneously. The DGX-CS65-13-0/0, DFX-CS65-13/6-0/0 and the DFX-CS65-32/18-0/0 models are useful for collocating multiple wireless services in one antenna. This allows the user to upgrade the network without adding cost. The polarization is 645° slant, cross. The gain for these models is between 11dBi and 15dBi, with between 15.5dBi and 17dBi for the 13-0/0 model. The electrical tilt for these antennas is 0°.
