Stack Dipole Array Base Station Antennas, 118 to 520 MHz

Stack dipole arrays deliver good gain and cover an entire communication band

For Airband, VHF and UHF communications, this range of 2 stack and 4 stack dipole array base station antennas deliver good gain and are factory tuned to cover an entire band at less than 1.5:1 VSWR.

Constructed from either aluminium or stainless steel, each dipole in the array is end fed in phase via a power divider neatly concealed inside the 50 mm diameter mount tube.

The dipole spacing of both the 2 stack and 4 stack models is calculated to give maximum accumulated gain and minimum side lobes in an array form.

Terminated with an N-Female connector, the arrays are rated for up to 250 watts input power.

For the 2 stack model, two clamps will be required to secure the array top and bottom. For the 4 stack model, three clamps are recommended to secure the antenna top, centre and bottom.

There are various methods of mounting these stack dipole arrays to a mast or tower. Clients are invited to consult ZCG Scalar for advice about the heavy duty clamps available to best suit their mounting arrangement
