dipole - Pondering variations on the vertical bazooka antenna

WebJul 22, 2024 · Pondering variations on the vertical bazooka antenna. I've seen these antennas built out of coax that are called a bazooka vertical. It's a kind of 1/4 wave vertical, or perhaps a 1/2 wave dipole. Constructing such an antenna is to roll back the outer braid of coax to expose 1/4 wavelength of the center conductor, the braid being folded back ... Webouter surface of the coax shield. Second, the coax segments would provide some reactance, presumably inductive, which would lower the resonant frequency of the basic dipole. In order to simplify thinking about these two functions I redraw the antenna as: Coax Center Conductor Soldered to Coax Braid 1.73 meters of RG58 Coax Velocity Factor … WebTunes/loads easily. Marc, DL5NA, gave me an SSTV RSV of 585. Some stations come in slight weaker than with my Cobra dipole, others same strength. Below is the plot from my miniVNA antenna analyzer (antenna + coax + choke balun). The resonance peak has moved up a couple of 100 kHz with respect to the mini-dipole.
