GP 160
¼ λ Glass fibre Ground-Plane Antenna for the 160 MHz Band
Description
- GP 160 is a glass fibre 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 VSWR-meter.
- The antenna comprises a GP-head made of chromed brass, one glassfiber radiator and three glass fibre radials.
- GP 160 is made of first-class materials and will endure “wear and tear” for years – no maintenance required.
- LW-SS-1″ mounting bracket and GP Adaptor is available as accessories.
