}\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.
