GP 80/160
1/4 λ Glass fibre Ground-Plane Antenna for the 80 MHz and
160 MHz Bands
DESCRIPTION
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.
