Ground Plane AntennasGP 450 B

Broad-banded, antistatic ground-plane antenna for the 450 MHz band

Description

  • GP 450 B is a broad-banded, 0 dBd, ground-plane antenna of the triple-leg type.
  • The antenna is fully universal as it covers the complete band: 380 - 470 MHz.
  • Atmospherical discharges are immediately led to gound, as all metal parts are DC-grounded. (Consequently, the antenna shows a DC-short across the coaxial cable).
  • GP 450 B is made from corrosion-resistant aluminium, which together with a special anodizing process gives this antenna a very long lifetime.
  • LW-SS-1" mounting bracket and GP Adaptor is available as accessories.
