Description
The 02590 Discone Antenna is a broad frequency antenna suited to applications across the frequency range 110-400 MHz (Transmit) and 100-400 MHz (Receive). All radiation patterns have been tested and verified on an antenna test range. Its stable radiation pattern across the 100-400 MHz band allows for accurate EMI / RFI testing. 

Robust construction of both the central feed section and matching radials makes for a reliable and attractive antenna.

Applications
Broad Band Transmit and Receive applications requiring coverage of numerous commercial frequency bands.

Construction

  • Hub matching section is constructed of Aluminium and Delrin. 
  • Mounting tube is constructed of Aluminium.
  • Radials are constructed of Aluminium.
