ANTENNAS
PCS-/DCS-/ISM-band Dual-patch Antennas
These antennas provide for reception and transmission in the 1850 to 1990 MHz, 1710 to 1880 and 2400 to 2500 MHz frequency bands with a low profile design for minimum visual impact, making it a good choice for discreet antenna installations. The units provide gain of 12 dBi with a nominal 66° x 25° half-power beamwidth for the 1850 to 1990 MHz and 2400 to 2500 MHz frequency bands and a nominal 64° x 26° half-power beamwidth for the 1710 to 1880 MHz band. In addition, impedance is 50 W and SWR is 1.5. The antenna housing is vacuumed formed out of thermoplastic in a rugged UV-stabilized radome that is weather resistant for outdoor applications. Size: 6" x 13" x 1".
