Double Bazooka NVIS Antenna Calculator. 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.
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 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.
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.

These graphs vividly depict the bandwidth problem on the lower frequencies, with the results varying significantly with antenna height. Fig 1. EZNEC models of dipoles from the standard formula, fed directly with 50 ohm coax (blue line) or series matched (purple line).
