}\BASE STATION ANTENNAS 27-520 MHz MONOCONE GROUND PLANE ANTENNAS Models 136, 236, 236-A, 336 70-520 MHz * Omnidirectional, vertically polarized, unity gain, monocone ground plane antennas. * These models have constant impedance and pattern over a wider bandwidth than conventional ground plane antennas, and a lower angle of radiation. * Models 136, 236, and 336 are constructed of strong aluminium alloy tubing with the antenna radiator enclosed in a PVC radome to reduce precipitation static. * Model 236-A is a special heavy duty, Civil Aviation Authority type-approved antenna which covers the VHF aeronautical band. It is constructed of stainless steel and has an ABS radome. “VUE 1D AKIeAe * — Installation instructions provided. Models 436, 636 _ 27-10 MHz * These antennas use elements constructed of highly resilient fibreglass rods covered with high quality black shrink-fit tubing with a strong aluminium alloy boom. * All models are factory preset to a user specified frequency.
