Lens Technology Enabled™ Multi-Beam Tri Band Base-Station Antenna utilizes a patented spherical lens design with 4 isolated CBRS Band (3.55GHz – 3.70GHz) cross-polarized beams, 4 isolated High Band (1695MHz – 2690MHz) cross-polarized beams and 2 isolated Low Band (698MHz – 960MHz) beams, each beam has 2 ports to support 2×2 MIMO. RET for CBRS Band & High Band Beams 0°-20°. RET for Low Band Beams 0°-40°. RET for CBRS Band is factory set. CBRS gain is limited to 18dBi.
