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 SWR-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.
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.
