The SI400-O Series from Sinclair are In-Building Antennas that operate from 694 to 6000 MHz. These vertically polarized antennas have an omnidirectional radiation pattern and provide a gain of 2.1 dBi. They can handle an input power of 50 W, have a VSWR of 1.8:1, and a passive intermodulation (PIM) of -153 dBc. The antennas meet the strict building safety code specifications laid out by regulatory authorities such as the National Fire Protection Association (NFPA). They are available in an IP66-rated enclosure with a polycarbonate radome that measures 230 (Dia.) x 83 (H) mm with 4.3-10 (female) or N-type (female) connectors and a 30 cm long cable. These antennas have a low profile non-protruding form factor that blends into the environment easily and are ideal for public safety DAS applications.
