Rob (VK3BVW) does an excellent job of explaining the theory, design, construction, and use of the double bazooka antenna. This review examines double bazooka antennas designed for the 80 and 40 meter amateur radio bands.
If you're looking for an efficient, quiet, single band dipole antenna, you may want to consider the double bazooka antennas examined by Rob in this video. A double bazooka antenna doesn't require the use of a balun. The antenna consists of 50 ohm coaxial cable (such as RG-58) with the shield split at the center and the feedline attached to the open ends. The braided copper shield of the coax is the actual RF radiator, while the center conductor acts as a matching transformer to provide a DC ground.
Try a double bazooka antenna for your favorite HF band and see what happens. Experimenting with antennas is half the fun of amateur radio.
