Force 12 C3E plots

C3 vs C3E:

  • C3 – two elements per band for 10-15-20 meters
  • C3E (Enhanced) – same as C3 but with an additional parasitic element on 10m

The following plots were made in EZNEC with the virtual antenna at a height of 42 feet (12.8m) over real ground (1 Medium). Gain is referenced to an isotropic radiator so subtract 8 dB from the gain figures to reference the C3E’s gain to a dipole over identical ground.

Azimuth plots were made at the elevation of greatest RF radiation for each particular band.



C3E – 10 meters



C3E – 12 meters



C3E – 15 meters



C3E – 17 meters



C3E – 20 meters

    Is it possible to post your modified NEC file on this site? I’d like to use your design and add elements for 15 and 20m and then convert the entire antenna to a wire beam.
