GP 40

¼ λ Glass fibre Ground-Plane Antenna for the 40 - 70 MHz Range

DESCRIPTION

  • GP 40 is a glass fibre ground-plane antenna of the triple-leg type.
  • The antenna is tunable (by cutting) within: 40…70 MHz.
  • The cutting diagrams below 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 SWR-meter.
  • The antenna comprises a brass GP-head, one glass fibre radiator and three glass fibre radials.
  • GP 40 is made of first-class materials and will endure "wear and tear" for years – no maintenance required.

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.
