Webb Industries was recently awarded contracts from leading cellular operators for a range of in-building components for the distributed antenna systems (DAS) operations on their LTE networks.
Johannesburg-based Webb is a leading installer and supplier of DAS systems using mainly Comba components for in-building solutions at highly competitive prices.
Some of the Comba components that Webb supplies include:
* Wideband power splitters covering 698–2700 MHz with low loss, flat response and even output;
* Directional tap-off couplers covering 698–2700 MHz and featuring 200 W power capability, low loss and good PIM performance with 7/16 DIN or N-type connector;
* 10 W adjustable attenuators covering the frequency range of DC–3 GHz with attenuation values of 0–30 dB and boasting low insertion loss and VSWR;
* 3 dB wideband hybrid couplers which cover 698–2700 MHz at 200 W average power, with low insertion loss and VSWR, high isolation and good PIM performance;
* Indoor omnidirectional ceiling mount antennas covering 698–2700 MHz, featuring high gain of 4,0 dBi in GSM 1800 and UMTS bands, and camouflaged and aesthetic for internal use in both SISO and MIMO applications;
* Multi-operator combiners for CDMA2000, GSM900, GSM1800 and WCDMA services, with 10 W input power per port, inter-band isolation, low insertion loss and intermodulation;
* Multi-operator, multi-technology repeater solutions supporting a single system of up to three frequency bands, easily configured for optical fibre distributed applications by adding MU (master unit) and RU (remote unit). The MU can support up to four RUs by adding an additional optical module.
