WideBand 20dBi 45 Deg 2.3-2.7GHz VPOL Sector Antenna-- (N Fem Integrated Connector) The 60deg, 90deg and 120deg vertically polarized base station sector antenna systems offered by Laird Technologies are constructed of UV stable fiber glass radomes. The 45deg sector has a UV Stable ASA plastic radome. The radome construction gives long service life under the most demanding conditions. The antennas are constructed using corrosion resistant metal elements and a unique air dielectric system which are more stable than PCB based antenna systems because they don�t absorb moisture, which can degrade the performance of PCB based antenna systems. The sectors come with a stainless steel scissor bracket mounting system for ease of installation and alignment. Features and Benefits: Vertically polarized wide band performance 45, 60, 90 and 120 deg models with gains from 16dBi to 20dBi Type N female integrated connector Extremely rugged for long service life in extreme environments Weatherproof Applications WiMAX applications Base station antennas 802.11b and 802.11g wireless systems Point to multi-point systems Broadband wireless access MMDS applications
