Description

Features: The FSA Series arrays have approximately 105 degrees horizontal beamwidth and offer 5 or 7dBd gain. The use of the flat screen reflector boosts the front-to-back ratio considerably allowing for tailoring antenna patterns for frequency re-use in extended networks. FSA Series Arrays feature the same solid construction as the standard array series. The folded dipoles utilize an internal phasing harness in a PTFE-based PIM-rated coaxial cable with IP-rated termination. The screens themselves are also made of premium grade structural aluminum further assisting in the mitigation of PIM. Consisting of Aluminium construction and superior internal harness design these antennas provide not only excellent radiation characteristics but also defined, high levels of intermodulation and noise suppression. IM performance is -140dBc based on a two-carrier test. The entire array rests at ground potential and offers the ultimate in lightning-resistant antennas. • Offset (cardioid) pattern with 105 Degree nominal Horizontal Beamwidth • High front to back ratio to allow frequency re-use by tailoring coverage areas • Hermetically sealed internal PTFE based phasing harness capable of 500W continuous operation. • Shipped unassembled for ease of handling, easily assembled on-site • Direct DC grounded for lightning protection and reduction of precipitation static noise • Industry-leading dual sectioned antenna PIM ratings (-140dBc) providing low IM and low noise characteristics for optimum performance
