"VARI-TILT"
OMNI ANTENNAS WITH ELECTRICAL BEAMTILT |
![]() The New Industry Standard "VARI-TILT" Base Station Antennas (patent pending) utilize a unique design that provides an omnidirectional radiation pattern with a field adjustable Variable Electrical Beamtilt (VEB) capability. This medium gain antenna allows you to custom tailor your coverage areas by utilizing field adjustable VEB that gives a total negative beamtilt range of 3 degrees to 8 degrees below the horizon. At maximum beamtilt, more energy is focused below the main beam for null-fill resulting in enhanced close-in coverage. The beamtilt may be adjusted at the antenna even after installation, without removing the radome or the inconvenience of changing jumper cables and re-weatherproofing the connectors. The beamtilt is easily determined by viewing the Calibration Rod (which slides in and out of the antenna base) while adjusting the VEB with a hex tool (supplied). No special tools or test equipment required!
