Description
These arrays utilize an internal phasing harness using PIM-rated PTFE-based coaxial cable as well as a custom dipole design to improve weatherproofing and resist bird attack. The use of a unique phasing arrangement provides extensive sidelobe suppression and null fill characteristics. The arrays will accept an input power level of 500 watts continuously, making them ideal for high-power multiple transmitter applications. The BA80 series are offered with 3°, 5° or 8° downtilt, to further enhance close-in coverage characteristics. All welded alodined aluminum construction and new fabrication techniques in both the harness and dipole sections have proven to minimise intermodulation and noise generated within the antennas. The entire array rests at ground potential and offers the ultimate in lightning-resistant antennas. • New 4.3-10 high-performance connector • Ideal for highly populated sites requiring long haul omnidirectional coverage • Operate over entire 330-420 or 400-520 MHz bands • 3, 6 or 9 dBd gain versions available • Inverted mounting version available • Versions with 0°, 3°, 5° or 8° of downtilt available in the BA80-67-P • Extensive sidelobe suppression and null fill • Industry-leading PIM ratings (-150dBc) providing low IM and low noise characteristics for optimum performance Further options include: (1) Factory pre-set downtilt of 3°, 5° or 8° may be specified on BA80 series antennas using model no. trailer – T3, -T5 or -T8 (2) Ruggedised black powder coat finish (aids in ice shedding for extreme conditions) is available on all aluminum arrays. (3) BA40 and BA80 series may be optionally supplied in all-welded 316 Marine Grade Stainless steel. Dimensions vary slightly
