  • COL27
This antenna can be used in multiple transmitter or paging applications at 200 watts input. Being relatively broadband, the COL27 caters to bandwidths of 5% of the specified frequency (It is advisable to specify both transmit and receive frequencies when ordering).

The COL27 is a series fed collinear design with the radiating element housed in a heavy duty fibreglass radome, fitted with an alodined aluminium mounting tube.

This antenna has been specifically designed to maintain stable vertical radiation pattern characteristics at the extremities of the tuned bandwidth. This ensures reciprocity of transmit and receive signal characteristics.The lightweight design delivers minimum wind loading and is ideal for mounting on moderate support structures.
