"Double-Bazooka"

Broadband Dipole Antenna

Bernie, WB6PFH, built and fell in love this Double-Bazooka antenna. He highly recommends it as a simple, very broad band antenna. One of his contacts in Texas claimed a 3dB improvement over his old dipole after switching to this antenna at Bernie's suggestion. The only caveat is that an antenna tuner must be used.

The design is easy to replicate and uses common materials. It is mostly made of RG58U coax, #16 automotive wire, rope suspension, and any plastic that can be cut into insulators.

This antenna has been used on 80 through 10 meters by cutting it to the center frequency.

For example:

The lower end of 80 Meters is 3.5 MHz.

The upper end of 10 Meters is 29.7 MHz

The harmonic mean (center frequency) of these frequency extremes is 10.2 MHz.

 

Harmonic Mean = √(LowFrequency x HighFrequency)
