The double bazooka antenna, often described as a coaxial dipole, is a time-tested antenna design widely used by amateur radio operators. Its popularity comes from a combination of simple construction, predictable impedance behavior, and noticeably lower received noise compared to thin wire dipoles.
The Bazooka coaxial dipole is a broadband antenna using coax cable as both radiator and quarter-wave sleeve balun, naturally matching 50 Ω feedlines. This guide explains its design, operation, dimensions, and VHF/UHF scaling for efficient omnidirectional performance
