“Elevated-Feed” ½ λ Dipole Antenna for Portable Equipment in the 2500 MHz Band

Description

  • Flexible skirt dipole antenna element built into an elastic shroud of hard-wearing and weather- and shockproof plastics.
  • “Elevated feed” ½ λ dipole antenna element – groundplane independent.
  • High gain and efficient decoupling from the portable equipment due to half-wave design.
  • 3 dB gain (typ.) compared to a ¼ λ antenna whip on the same equipment.
  • Highest quality materials in a modern “High-Tech” design.
  • Delivered factory tuned to customer’s specified frequency.
  • Provided with TNC(m) connector.
