ELF 2500/…-TNC
“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.
