UHF Elliptical Dipole Array 330-420 MHz - 5 dBd
The EA40-57 array utilises an internal phasing harness using PIM rated PTFE based coaxial cable as well as custom dipole design to improve weatherproofing and resist bird attack. The main lobe of these antennas is strong and highly controlled with extensive side lobe suppression ensuring the integrity of the pattern. To further boost performance, users of the EA80 array may specify beamtilt of 0, -3 or -5 degrees. Superior performance is maintained over the entire operating bandwidth of the antenna (330-420 MHz or 400-520 MHz). VSWR is maintained at <1.5:1 and input power levels of 500 watts are catered to for true high density site requirements. With all welded construction and superior internal harness construction (using highly stable PTFE based cables) the antennas provide not only excellent radiation characteristics but also high levels of intermodulation and noise suppression. IM performance is a world leading -150 dBC based on a two-carrier test.
The entire array (UHF Elliptical Dipole Array 330-420 MHz - 5 dBd) rests at ground potential and offers the ultimate in lightning resistant antennas. 4.3-10 high performance connector Ideal for highly populated sites requiring "corridor" style largely bidirectional coverage 5 dBd or 9 dBd gain versions available Inverted mounting version available. Extensive side lobe suppression and null fill Hermetically sealed internal phasing harness Industry leading PIM ratings (-150 dBc) providing low IM and low noise characteristics for optimum performance (1) Factory pre-set downtilt may be specified on EA80-67 series antennas using model no. trailer T3 or -T5 (2) EA40 and EA80 series may be optionally supplied in all welded 316 Marine Grade Stainless steel. Dimensions vary slightly.
