Build Your Own Bazooka Dipole: A VHF/UHF vertical dipole made from coax
-
This is a deviation from the wonderful antenna the Double Bazooka. The Vertical Bazooka, is made entirely from RG-8U coaxial cable.
-
The Little Stick antenna is an aluminium version of the Vertical Bazooka design which was made from coax.
-
A quarter wave vertical omni-directional antenna for 7 MHz. Formulas for dimensions in feet and meters are provided. Ideal radial angle is between 35° and 45°. Velocity factor (Vf) varies based on coax type.

The Bazooka antenna, a coaxial dipole, functions as an omnidirectional antenna with vertical or horizontal polarization. Patented in 1939 and refined in 2006, it features a quarter-wavelength coaxial cable with separated conductors. The outer conductor connects to a sleeve, while the inner conductor extends vertically. Initially complex, it has been simplified for versatile use, including military applications. Adding elements can modify its behavior for NVIS or Yagi-Uda configurations. Experiments in 2007 at the Campus de Pesquisas GeofÃsicas in Paula Freitas-PR demonstrated consistent VHF and UHF performance, showing reliable return loss measurements despite variable weather.
