Bazooka Antenna Projects
Amateur radio antenna projects with detailed plans and calculators
The Bazooka antenna, often built as a double bazooka, is a popular monoband design known for its wide bandwidth and quiet reception. Operators frequently choose this coaxial dipole for HF bands, but it can also be adapted for VHF and UHF. Its construction typically involves coaxial cable, making it a straightforward homebrew project for many hams looking for a robust and efficient antenna.
Hams can find numerous antenna projects and construction guides for various bands, from 40 meters to 70 cm. Many resources discuss the performance characteristics of the double bazooka, including its broadband nature and gain, often comparing it to traditional dipoles. Discussions on forums like eHam.net and mailing lists such as Towertalk provide practical insights into building and deploying these antennas, even in challenging locations like attics.

The Dipole Bazooka Antenna for 40 meters is a popular choice among amateur radio operators. Its design allows for easy construction using materials like RG58 coaxial cable and PVC. Measurements are calculated using specific formulas; for instance, at a frequency of 7,100 MHz, the total length is approximately 19.74 meters. This antenna offers a performance range of 97% to 99%, with an impedance of 49 to 52 ohms. Additionally, it can handle up to 1 kW of power and requires no modifications for connection. -

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 Geofísicas in Paula Freitas-PR demonstrated consistent VHF and UHF performance, showing reliable return loss measurements despite variable weather.
