Antenna signals performance WLAN

A new omni-directional antenna available from Admiral Microwaves will dramatically improve the performance of 802.11n wireless networks in a wide variety of installations. The S24493TS, manufactured in the US by Cushcraft, part of the Laird Technologies group, is low cost, compact and easy to install. This dual band, three-element, vertically polarised, omni-directional antenna is specifically designed for use in 802.11n MIMO applications, typically used in offices, hotels, schools and universities, airports, stations, hospitals, libraries and shopping centres.

The radiation patterns are uniform and symmetrical, providing high levels of signal density across defined zones. Greater predictability of signal coverage helps improve the performance and reliability of wireless network systems. The dual band frequency coverage means that a single type of antenna can be deployed with any MIMO radio in either the 2.4 to 2.5GHz or the 4.9 to 5.9GHz bands.

Technical specifications include: 3dBi gain nominal in the 2.4 to 2.5GHz range and 4dBi nominal in the 4.9 to 5.9GHz range; maximum VSWR of 2.0:1, and maximum input power of 2W.

Housed in a compact, low profile (308.2 x 22 x 92mm), PVC/acrylic radome, the S24493TS can be easily mounted to a variety of drop ceiling grids using the integrated spring clips. It can also be mounted to a flush surface via the four mounting holes provided. Each of the three MIMO antenna elements is connected to the WLAN Access Point using a low loss, plenum rated coax pigtail. A wide choice of coax lengths and connector types are available.

These RoHS compliant, omni-directional antennas are already available in stock in the UK from exclusive, specialist distributor, Admiral Microwaves. The price is around 50 each, depending on the size of order. Delivery is 3 to 5 weeks from receipt of order.
