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.
18 kwi 2022 · Bazooka Antenna Calculator. The following calculator will help you calculate the length of all your antenna elements. Enter the center frequency of the band you want to use and the velocity factor of the coax.
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.
Double Bazooka Antenna - Calculator. Uploaded by. Steven Baynes. AI-enhanced description. This document lists antenna lengths for different frequency bands. It provides lengths for quarter-wave, half-wave and full-wave antennas at center frequencies of 3.7 MHz and 7.1 MHz for the 80m and 40m amateur radio bands respectively.
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 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.
