Part Number:DBB-4020

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's rarely survived 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.

  • IAC has taken the same high performance, Mil-Spec quality construction and applied this into a 40/20 Dual Band Antenna.
  • 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 a 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 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 eliminates the need for antenna matching baluns and can be fed directly with 50 Ohm coax. The 40/20 DUAL BAND BAZOOKA is extremely efficient and typically provides SWR readings of less than 2:1 over most of the 40 and 20 meter amateur bands. Under certain conditions a wide range antenna tuner may be required to obtain a lower SWR.
  • Since this antenna has no exposed metal wire static charges cannot build up thus reducing noise by 6 dB over antennas constructed of exposed wired.
  • The 40/20 DUAL BAND BAZOOKA antenna will handle 3 KW continuous power with no effect to performance.
  • The 40/20 DUAL BAND BAZOOKA is recommended to be mounted in an inverted “V” configuration for optimum results.
  • In addition to the listed bands, you will find that our DUAL BAND BAZOOKA antennas will also operate on some other bands with the aid of an antenna tuner.
