Double bazooka coaxial dipole broad-band, W5BGP
The inside sections, do not radiate, but act as quarter-wave shorted stubs which presents high resistive impedance to the feed point at resonance and tends to cancel reactance as frequence off resonant frequencies

Double Bazooka Dipole
consist of a half wavelength piece of coax RG58 with the shield split at the center and the feedline attached to the open ends

Antenne double-bazooka
The double-bazooka consists of 1/2 lambda of coaxial cable cut at its center or twice 1/4 lambda
