VHF Binary Dipole Array , 2 x 3dBd, 136-174MHz
These high performance VHF dipole omnidirectional arrays are for use in highly populated radio sites requiring long haul omnidirectional coverage. The arrays feature high gain, low noise performance and enhanced null fill coverage with omnidirectional coverage characteristics.
Each of the dipoles are fed via an internal phasing harness in stable, PTFE based double-screened coaxial cable with PE jacket for optimum weatherproofing. These omnidirectional arrays incorporate extensive sidelobe suppression and null fill, and the binary phasing arrangement ensures consistent omnidirectional coverage and vertical pattern control.
This array provides unparalleled bandwidth, covering the entire 136-174 MHz band and offer gain of 2 x 3dBd over the band with a VSWR of less than 1.5:1. With input power levels of 750 watts, the antenna is ideal for high power paging sites or high density, multi-channel installations requiring maximum performance and service life.
With all welded construction and superior internal harness construction, these antennas provide not only excellent pattern characteristics but also defined, high levels of intermodulation and noise suppression. The entire array rests at ground potential and offers the ultimate in lightning resistant antennas.
