  • The radiator is measured from its free end to the bottom of the black insulator, while the radials are measured from their free ends to where they meet the GP-head.
  • GP 80 is a glass fibre ground-plane antenna of the triple-leg type.
  • The antenna is tunable (by cutting) within its main frequency band: 66…88 MHz but is further applicable up to 150 MHz.
  • The cutting diagrams on the diagrams tab indicate the length of the radiator and the radials corresponding to a specific frequency. It is recommended to use the curves as a guide and fine-tune using an VSWR-meter.
  • The antenna comprises a brass GP-head, one glassfiber radiator and three glass fibre radials.
  • GP 80 is made of first-class materials and will endure “wear and tear” for years – no maintenance required.
  • LW-SS-1″ mounting bracket and GP Adapor is available as accessories.
