ANTENNAS
Portable Antennas
These FLEXTRON portable antennas are designed for specialized or standard cellular, PCS and ISM-band applications. The company has available 5/8-, 1/2- and 1/4-wave designs in rugged injection-molded, neoprene or the economical polyvinyl-chloride-coated shrink sleeve. Telescoping and articulating coil and whip designs are also available for device applications. All of the antennas are available with a variety of connectors and adapters, and can be optimized to a specific application.

PCS/DCS Dual Linear Patch Antenna
The model S1857HVP12NF PCS/digital communications system (DCS) dual linear patch antenna provides for reception and transmission of linearly polarized signals in the 1850 to 1990 and 1710 to 1880 MHz frequency bands. The antenna is composed of a broadband patch that provides a minimum of 7 dBi gain and features one feed for horizontal polarization and one feed for vertical polarization. The antenna’s SWR is 1.5 (max) on 50 W impedance. The housing is vacuumed formed out of polyvinyl chloride in a rugged, UV-stabilized radome that is weather resistant for use in outdoor applications. Size: 6" x 6" x 1".
