Bazooka Antenna Measurements Per Band

Bazooka Antenna Measurements Per Band

This page contains the calculated measurements of the Bazooka antenna for each HF Ham band, and 6 meters.  Each of the photos below are pretty self-explanitory. 

If you try to calculate the measurements yourself, and come up with slightly different figures than I have listed in the photos below, there is a good reason for that.

The length measurements in my diagrams are rounded off to the next closest 1 inch.  This was done for one reason only.  It is easier when you do the measuring to build your own Bazooka.  The measurements are not that crucial as long as they are within 1 little inch.  If there is a 1/2 to 3/4 inch difference in actual lengths, it will not have any effect on how the antenna will tune or perform.  But no matter what you do, never go over more than that 1 little inch. 

If you use the measurements I have provided for each band Bazooka below, and be sure you make all measurements on each side of the feedpoint exactly the same, you should have a top performing antenna that will do better than any straight wire dipole type of antenna.

If you have any questions about these antennas or the measurements, please feel free to contact me at k3dav_msn.com

The top of each photo diagram tells you what band the antenna is designed for.

You can right click on any of these diagrams and save them to your computer as a photo.
They are all in jpeg format.

This cut has worked well for many hams on the 60 meter band.  We took the frequencies of channel 1 and channel 5 and cut this antenna to the exact center between both frequencies.  If the FCC changes or expands the frequency allocation of this band in the future, a new diagram will be made to reflect those changes.

The phone portion of 15 meters is a little bigger than other HF bands,
so the actual cut frequency is a little above the center of the band.

Yes we even did one for CB’ers who want good DX from a Bazooka.

10 meters is a slightly bigger band covering 1.7 MHz.  Most hams on 10M stay between 28.0 and 29.0MHz.  The top end of 10 meters is for FM and a few repeaters which are not heavily used.  So this diagram cuts the 10M antenna to 28.5 to cover mosly the CW and SSB portions of the band.

The following are 2 photo diagrams for 6 meters.  6 meters is a large band at 4 MHz wide, but a Bazooka only has a good SWR over a 2MHz bandwidth. 

With this in mind, the first diagram below is for the lower end of 6 meters to cover the SSB and AM portion of the band.

The second diagram is cut to the center of 6 meters, but will cover the 1MHz up and down where most repeater inputs and the FM simplex frequencies are located.  The frequencies from 53 to 54MHz are mostly repeater outputs, and you n do not transmit there.

NOTE:  But with a tuner, the 6M FM version will also cover the lower SSB & AM portion, even though the efficiency will be slightly lower than with the SSB/AM version of this antenna.
