Antenna system Important features

4/22109-FGC101763 Uen Rev B Limited Internal 2005-07-263

! Optimal RF performance no weak links in RF chain! Antennas for all applications from rural to dense urban,

Highway, Street and Indoor applications! High quality Max reliability - No maintenance! Single, double and triple antennas! Designed for low visual impact! Remote tilt support for each individual band! Attractive Cost with minimal OPEX! One stop shopping simple logistics

The coverage is set by the RBS... and the antenna system

2 dB less link budget because of the RBS or the antenna

system

RBS

The dB in the Antenna system are just as important as the dB in the RBS specification!
