Upgrading WiFi antenna boosts operating range
CTi is launching a new series of omni-directional WiFi antennae that provide a range of gain levels up to 9dBi, which is claimed to be a significant improvement over most standard antenna fitted to indoor wireless access points, routers and bridges. The new CTI-RA series WiFi antenna enable users to increase the signal strengths of SOHO (small office/home office) wireless equipment significantly; simply by replacing the supplied antenna, they can extend the equipment's operating range appreciably.
Suitable for use with any 802.11 standard 2.4 GHz wireless systems, CTI-RA antenna are available with a choice of 3dBi, 5dBi, 7dBi or 9dBi gain levels to facilitate optimum application matching, and with three types of connector: SMA Male RS, TNC Male and N Male. All six antennae employ co-linear elements to maximise RF efficiency and minimise length, contained within a robust, semi-flexible rubber housing. The base of each antenna features a swivel joint that enables it to be used for vertically or horizontally polarised signals, and the connector is fitted with high-quality gold-plated pins for signal integrity. CTI-RA antenna have a nominal 50 Ohm output impedance and an output VSWR (voltage standing wave ratio) of less than 2:1 across the band.
CTi has also recently introduced a series of 5GHz WiFi antennae, together with a number of new GPS and GSM antennae. In the light of this rapidly expanding product portfolio, the company has launched a new web site - www.cti-int.com - that makes it much easier and quicker for designers, OEMs and system integrators to find an exact match for their antenna requirements. Making extensive use of drop-down menus and scrolling display windows, the new site enables users to navigate their way through CTi's extensive range of products, and to obtain on-line guidance on a variety of technical issues - such as antenna frequency and efficiency. The site currently details nearly 100 different WiFi and Bluetooth antenna - as well as a wide range of models for GPS, GSM, DAB and Tetra applications - together with large number of adaptors and adaptor leads. The adaptor leads can be made up to suit any requirement at the UK-based manufacturing facility.
In addition to providing comprehensive technical information about all of CTI's standard antennae, the new website features on-line enquiry and quotation forms, offers a sneak preview of products in development, and lists full contact information for all of the company's distributors, worldwide.
