Air Band Sidemount Dipole Antennas

The B42 sidemount dipoles are for Air Band communications across the entire frequency range 118 to 136 MHz at better than 1.5:1 VSWR.

• B42 is constructed from aluminium.
• B42SS is manufactured entirely from stainless steel and is more suitable for harsh environments and areas where extreme weather conditions prevail.

The exceptionally broad bandwidth and reliable construction make a sidemount dipole perfect for use as a base station antenna.

Nominally 0 dBd gain for a single bay, approximately 2.3 dBd of forward gain results by using the mount pole as a reflector at 0.2 wave spacing.

Mast to tower distance can be varied to produce the desired radiation pattern.

To achieve higher gain and power, mount dipoles in stack array formations using a power divider or phasing harness. Note that ZCG Scalar also manufacture 2 and 4 stack dipole arrays with internal power divider especially for this purpose.

Radiating elements operate at DC ground potential to eliminate static noise and interference.

An N-Female connector rated for up to 250 watts power is fitted to the 1 metre RG213 cable tail.

A right-angle mast mounting clamp, coaxial feeder cable, connectors and other installation accessories are all available separately to complete the installation.
