Description
The 02677 Discone Antenna is a broad frequency antenna suited to applications across the frequency range 410-1200 MHz (Transmit) and 400-1200 MHz (Receive). All radiation patterns have been tested and verified on an antenna test range. Its stable radiation pattern across the 400-1200 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 construction of Aluminium and Delrin. 
  • Mounting tube is constructed of Aluminium.
  • Radials are constructed of Aluminium.
