Description

A DOUBLE BAZOOKA antenna is an extremely broad-banded Half Wave Antenna that 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 twin lead connection. The IAC design is 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-Spec quality.

The VERTICAL BAZOOKA provides an efficient low profile quarter wavelength vertical antenna good for local operation and great for DX providing a low angle of radiation with low noise reception. Due to its low profile it is an ideal choice for deed restricted areas where stealth is required. No more need to compromise on indoor attic antennas.

  • IAC has taken the same high performance, Mil-Spec quality construction and applied this into a quarter-wavelength VERTICAL BAZOOKA antenna.
  • Antenna construction centers around 50 ohm Belden 8259 coax cable in combination with 300-Ohm transmission line end section. The result is an end feed broadband quarter-wavelength inverted-L antenna.
  • Provided for the operator's 50 Ohm feed line is an SO 239, a silver plated connector having Teflon insulation.
  • The features of the proprietary design anchor the connector in high shear UV resistant molding. The coax element is 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. A heat shrink cap is applied to the outer most end of the twin lead completing antenna construction.
  • This unique design eliminated the need for antenna matching baluns and can be fed directly with 50-Ohm coax. The VERTICAL BAZOOKA typically provides SWR readings of less than 2:1 over the entire amateur band.
  • Since this antenna has no exposed metal wire static charges cannot build up thus reducing noise by 6 dB over antennas constructed of exposed bare wires.
  • The VERTICAL BAZOOKA antenna will handle full legal limit power with no effect to performance.
  • The VERTICAL BAZOOKA is recommended to be mounted alongside a tree or wooden support pole but can be mounted beside a tower. The VERTICAL BAZOOKA should run parallel to the tower approximately 24 inches away. See installation instructions page for more details.
  • All VERTICAL BAZOOKA antennas can operate on other bands with the aid of an antenna tuner.

The overall antenna length of the VERTICAL BAZOOKA antenna is approximately 33 feet.

NOTE: A TUNER MAY BE REQUIRED DEPENDING ON GROUNDING SYSTEM AND SOIL CONDUCTIVITY.
