Cutting Diagrams
GP 80
¼ λ Glass fibre Ground-Plane Antenna for the 80 MHz Band
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.
- 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.
