COL53 -140 Features:

  • Excellent bandwidth providing full band coverage

  • Internally DC grounded for lightning protection and the reduction of precipitation noise

  • Patented Meander™ PCB design for optimum RF pattern stability

  • Industry leading PIM ratings (-150dBc) providing low IM and low noise characteristics for
    optimum network performance

  • Excellent Peak Instantaneous Power(PIP) rating (25kW)

  • Also available with N connector(see note)


The patented Meander™ collinear element design allows multiple half wave elements to be stacked without the variations in cable lengths and mechanical joints which have typified the construction techniques in high gain collinear antennas. With the dipole elements being printed on a single sided PCB the susceptibility to passive intermodulation is practically eliminated.

Placing the elements on a board not only controls PIM but also removes manufacturing variations so that each and every antenna will provide the same pattern, tilt and VSWR characteristics over its operating bandwidth.
