High Performance, Low Profile Antennas
The ValuLine" series high performance, low profile 0.3 and 0.6 m antennas meet the performance and budgetary demands of cellular, PCS and private-user networks worldwide and are available in 22, 26 and 38 GHz frequency bands. The antennas’ low profile results in reduced windloading and minimal visual impact, and the units can be painted to match their surroundings. The cost-effective, small-diameter, high frequency antennas can be customized for direct integration with original equipment manufacturer (OEM) radio systems. The units are fabricated from aluminum with galvanized mount components and stainless-steel hardware for assured performance regardless of environmental conditions.

2 - 18 GHz Direction-finding Antenna
The model C390-169 broadband direction-finding antenna operates from 2 to 18 GHz. The antenna assembly consists of an ELPAR reflector, an omnidirectional reference antenna and a radome enclosure. The reflector shape is parabolic in the azimuth plane and elliptical in the elevation plane, producing a directional beam in azimuth and a small-variation beamwidth in elevation. The antennas are enclosed by a broadband, high transmission efficiency radome. The antenna assembly, which can be mounted on a rotator, is suitable for ground-, mobile- or shipboard-rotating direction-finding applications. Specifications for the reflector include a gain of 4.5 to 21 dBli, a sidelobe level of less than 15 dB, an SWR of 2 (max) and an SMA female input connector. Specifications for the omnidirectional antenna include a gain of –3 to 5 dBli, an SWR of 2 (max) and an SMA female input connector.

Linearly Polarized Beam-shaped Antenna
The model SR1857 antenna provides for reception and transmission of linearity polarized signals in the 1710 to 1880 MHz and 1850 to 1990 MHz frequency bands. The antenna has a broad H-plane beamwidth ranging from 120° to 180°. The unit consists of linear elements that provide a minimum of 7 dBi gain. SWR is 1.5 (max) of 50 W impedance. The antenna is housed in a rugged, low profile, UV-stable thermoplastic radome that is weather resistant for outdoor applications. Size: 11.75" x 5.50" x 0.75".
