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