Ground Plane AntennasGP 80/160

¼ λ Glass fibre Ground-Plane Antenna for the 80 MHz and 160 MHz Bands

Description

  • 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. The radials must be placed short/long alternately.
  • GP 80/160 is a dual-band glass fibre ground-plane antenna of the triple-leg type.
  • The antenna is tunable (by cutting) within its main frequency bands: 66…88 MHz/145…175 MHz. 
  • The cutting diagrams below indicate the length of the radiators and the radials corresponding to specific frequencies within the two bands. It is recommended to use the curves as a guide and fine-tune using an VSWR-meter.
  • The antenna comprises a brass GP-head, two glass fibre radiators and six glassfiber radials.
  • GP 80/160 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.
