02452C - Multi-Band Indoor Omni-Ceiling Antennas

02452C - Multi-Band Indoor Omni-Ceiling Antenna (patent# 710276)

Description

The 02452C is a Multi-Band indoor ceiling antenna covering the CDMA, GSM, PCS, DECT, 3G/UMTS, ISM, WIRELESS LAN, and BLUETOOTH, Radio Bands. The Multi-Band functions of the 02452C antenna negates the requirement for separate antennas. It is lightweight, simple to install, and ideally suited to indoor applications.The Radiation Patterns of the 02452C are deliberately inclined below the horizon enhancing low angle coverage.Its general construction ensures low intermodulation levels. A common feed ensures straightforward connections.

Applications

Indoor communications coverage for CDMA, GSM, PCS, DECT, 3G/UMTS, ISM, WIRELESS LAN, and BLUETOOTH bands. Ideally suited to indoor mounting through false ceilings.

Construction

The antenna is constructed in white high impact engineering plastics. The moulded stylised white radome offers a low profile and discrete appearance complementary to an indoor environment. The antenna is fed via a short RG142 cable tail fitted with a high quality "N type" female connector. The antenna ground plane is circular, and constructed of high quality light gauge Aluminium sheet. All radiators are constructed of brass, ensuring maximum radiation efficiency.
