ZCG Scalar Air Band Coaxial Dipole Antenna

 

Key Features

 

  • Lightweight weatherproof aluminium construction

  • Omnidirectional 360° radiation pattern

  • Broad 46° vertical beamwidth

  • Stainless steel mount tube

  • Made to order - specify any 3% of 118-136MHz when ordering.

 

Usage

 

  • The B14 and B18 omnidirectional coaxial dipoles are an effective and economical air band base station antenna

  • For use in the 118 to 136 MHz frequency range, specify any 3% bandwidth you require and your dipole will be manufactured and tuned accordingly at better than 1.5:1 VSWR

  • At the lowest frequency 118MHz the coaxial dipole will stand 3 metres tall

  • When manufactured for higher frequencies, the fibreglass radome height reduces slightly

  • An N-Female connector rated for up to 100 watts input power is located at the base of the mount tube

  • Mounting clamps, coaxial feeder cable, connectors and other accessories are all available separately to complete the installation.
