FM Bazooka Antenna for Superior FM Radio Reception (88–108 MHz)
Build a broadband FM Bazooka (sleeve dipole) antenna for 88–108 MHz with low noise, stable impedance, and excellent wideband FM reception. Ideal for DX listening and clear stereo broadcast signals.
Slim-Jim Antenna for FM Broadcast Band reception (88–108 MHz)
Build a Slim-Jim antenna optimized for 88–108 MHz FM broadcast reception. This ¾-wave vertical with integrated matching section delivers omnidirectional coverage, low noise pickup, and improved DX performance over simple dipoles or whips.
Understanding the Bazooka Coaxial Dipole Antenna Design
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
