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!
