8.5 to 10 eBdGAIN, 806-960 MHz

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!
  • VEB — allows fine tuning of cell site coverage by providing negative beamtilt adjustment capability from 3 degrees to 8 degrees before or after installing the antenna
  • Simplicity — VEB adjustment requires no additional hardware and does not require removal of the radome or possible loss of weatherproofing at jumper cable connectors.
  • Cellular — one antenna covers applications requiring negative beamtilt patterns from 3 degrees to 8 degrees below the horizon
  • Null Fill — precisely adjust beamtilt in a matter of seconds, for optimum null fill
  • Inverted Mounting — model ASP-978 provides uptilt
  • Offset Pattern — model ASP-975 now available, single reflector assembly included
  • Trunked —0 to-5 degrees, model ASPA977V5
