A DOUBLE BAZOOKA antenna is an extremely broad banded Half Wave Antenna which can operate efficiently across an entire Ham band with little change to the SWR. The DOUBLE BAZOOKA antenna design was first conceived as a radar antenna in the early 1940's for use by the U.S. Government. It was modified for amateur radio use in the 1950's. 

Home-Brew DOUBLE BAZOOKA rarely survive harsh elements and wind-load stresses. The weak points were typically at the feed point and coax to twin lead connection. The I.A.C. design is the culmination of a three year development program, including state of the art materials and encapsulation techniques, to provide the amateur radio operator with an antenna that will endure such harsh elements. Construction methods and components used are of government Mil-Specquality.

Antenna construction centers around 50 ohm Belden 8259 coax cable, in combination with 300 Ohm transmission line end sections. The end result is a center feed broadband full wave dipole.

Provided for the operator's 50 Ohm feed line is an SO-239, a silver plated connector having Teflon insulation and a gold plated socket.

The features of the proprietary design anchor the connector in high shear UV resistant molding. The coax elements are sealed in this molding, which exhibits high adhesion to the PVC jacket.

Mil-spec heat shrink tubing, with a melting inner liner, is utilized to seal and strain relieve the transition area between the coax and the twin lead. Heat shrink caps are applied to the outermost ends of the twin lead completing antenna construction.

This unique design eliminates the need for antenna matching baluns and can be fed directly with 50 Ohm coax. The DOUBLE BAZOOKA is 98% efficient and typically provides S.W.R. readings of less than 2:1 over the entire amateur band.

Since this antenna has no exposed metal wire static charges can not build up thus reducing noise by 6dB over antennas constructed of exposed wire.

The DOUBLE BAZOOKA antenna will handle 3000 watts continuous power with no effect to performance.

The DOUBLE BAZOOKA is recommended to be mounted in an inverted "V" configuration for optimum results. However the DOUBLE BAZOOKA can be configured horizontally with equally good results.

In addition to the listed band, you will find that our DOUBLE BAZOOKA antennas will also operate on some other bands with the aid of an antenna tuner.

The DOUBLE BAZOOKA can be configured as a phased array with an optional add-on kit.

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.
