13 - 38 GHz Low Profile Antennas
The ValuLine® series low profile antennas has been expanded to include antennas operating at 13 to 38 GHz for use in cellular, PCS and Private User Networks. The units can also be customized for direct integration with OEM radio systems. The electrical performance of the new antennas meets or exceeds the performance standards of the European Telecommunications Standards Institute, the Federal Communications Commission, the UK Radio Communications Agency and Germany's BAPT. The antennas are available in diameters of 0.3, 0.6, 0.8 and 1.2 m in frequencies of 13, 15, 18, 23, 26, 28 and 38 GHz.

3 dBi Omnidirectional Antenna
The model PCD800V 3 dBi omnidirectional antenna is designed to replace the standard rubber ducky or hip antenna on wireless telephone terminals or data devices. The unit allows the subscriber to place the antenna in a remote location for better signal strength. Power-handling capability is 10 W and SWR is less than 2. In addition, the unit is vertically polarized with an elevation pattern of 60° and 360° in azimuth. Size: 0.50" x 8.50". Models are also available to cover the cellular 824 to 896 MHz, PCS 1850 to 1970 MHz and spread spectrum 2.4 to 2.5 MHz frequencies.

Linearly Polarized Patch Antenna
The model S34017P linearly polarized patch antenna provides for both reception and transmission in the 3400 to 3600 MHz frequency band. The unit features a low profile design for minimum visual impact, making it suitable for discreet antenna installation. The antenna is designed with a microstrip array that provides a minimum of 17 dBi gain with a nominal 16° x 18° half-power beamwidth. Impedance is 50 W and SWR is 1.5. Each patch antenna combines good RF performance in a discrete and stylish antenna housing that can be mounted easily in challenging situations. Size: 11.000" x 10.000" x 0.875".
