The wire bicone is essentially an approximation to a solid biconical antenna, where the cone is replaced by radial wire conductors. This antenna is effectively a dipole modification which can provide wide-band operation without greatly increasing complexity. The wide angle biconical antenna is popular for its wide impedance bandwidth, omnidirectional radiation coverage and simplicity of mechanical design and installation.

The plots below show the performance of a 75 Ω, Fmin = 1 GHz design with 17 radials. The omnidirectional gain pattern as seen in the center graph remains almost constant across the operation band.

Performance of a 75 Ω, Fmin = 1 GHz design with 17 radials. Performance of a 75 Ω, Fmin = 1 GHz design with 17 radials.
