HX 4/2/FQ/FQ-FME

Helical Antenna with Universal FME-Connection System for Portable Equipment in the 4 m and 2 m Bands
Description
  • Flexible, conical steel helix moulded in thermoplastic rubber.
  • Significant reduction of length due to the helical principle.
  • Optimum performance compared to physical dimensions.
  • Delivered factory tuned and tested to ensure minimum VSWR.
  • Provided with universal FME-connection system for optimum flexibility and easily exchangeable connectors.
  • Designed for use with the following of Procoms line of black FME-connectors (to be ordered separately): BFME-UHF, BFME-BNC, BFME-TNC and BFME-N.
