The RFI BA40-57-P is a UHF binary dipole array antenna terminated with 4.3-10(F) and 0.5m RG142 Cable tail. It operates within the 330-420 MHz frequency range, offering a 3 dBd gain. These high performance UHF dipole arrays are ideal for highly populated radio sites requiring long haul omnidirectional coverage. They operate over entire bands and offer gains of 3, 6 or 9dBd (depending on model) exhibiting a VSWR of <1.5:1 across the band.
The BA40-57 arrays utilise 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 use of a unique phasing arrangement provides extensive side lobe suppression and null fill characteristics. The arrays will accept an input power level of 500 watts continuous, making them ideal for high power multiple transmitter applications. All welded alodined aluminium 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.
