The measurements below are for building a Double Bazooka Near Vertical Incident Skywave (NVIS) Antenna. The End Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. 300 Ohm Twin Lead with the ends shorted is an option for even greater bandwidth.
The 80 Meter DOUBLE BAZOOKA antenna will operate on 80 through 10 meters with the aid of an antenna tuner. The following chart gives overall antenna lengths and recommended height placement above ground for a single DOUBLE BAZOOKA.
31 gru 2023 · It is a project to build only one part of a double bazooka antenna system. The measurements of the limbs and stingers are band (or band section on 80 and 160 meters) dependent, so I’ll add the needed math in a post below this.
The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends.
29 sty 2024 · Double-bazooka-calculator. The calculation of the popular double bazooka antenna is easier than you can imagine. First a little debauchery about the construction of the double bazooka - or also called coax antenna.
The DOUBLE BAZOOKA phased array produces up to 4.5dB forward gain and a front to back ratio of typically 20dB over a single dipole antenna. The following chart gives overall antenna lengths and recommended height placement above ground for a single DOUBLE BAZOOKA.
Table 1 gives suggested lengths and separation distances for 160, 80, 40, 20 and 10 meter versions of the antenna. EZNEC wires 1, 2 and 3 are the “dipole” wire and EZNEC wire 4 is the “parasitic” wire referred to in Table 1. One must also tell EZNEC the type of wire that will be used in the antenna’s construction.
