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 side lobe suppression and null fill, and the binary phasing arrangement ensures consistent omnidirectional coverage and vertical pattern control. These arrays provide unparalleled bandwidth, covering the entire 136-174 MHz band and offer gain of 3 or 6 dBd over that band with a VSWR of less than 1.5:1. With input power levels of 750 watts, the antennas are suitable 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.
