DESCRIPTION:

+

GP 160 is a glassfiber ground-plane antenna of the triple-leg type.

+

The antenna is tunable (by cutting) within its main frequency band: 145…175 MHz,
but is further applicable up to 400 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 GP-head made of chromed brass, one glassfiber radiator
and three glassfiber radials.

+

GP 160 is made of first-class materials and will endure “wear and tear” for years
– no maintenance required.
