BCA Mark II High Gain Sector Antennas
Introducing the newest member of the Andrew BCA series
family, the Mark II high gain sector antennas. These
antennas incorporate new technology that significantly
improves pattern performance over previous designs.
They are available in a 90° sector size for 28 and 38 GHz
applications. Other sector sizes are available on request.
Product Features
•
High gain performance - 21 dBi @ 90°
•
Improved null fill for optimized coverage
•
Improved azimuth patterns for higher sector-to-sector
and transmit/receive isolation
