Coaxial antennas bazooka
Constructed using coaxial cable elements of reducing their size by exploiting the Velocity Factor of the cable. using typical 50 Ohm coax cable it might shrink an antenna to 66% its full size value

10m Bazooka, WD9N
This antenna up on my 21 foot telephone pole to test it and it has 1.5:1 SWR
The Vertical Bazooka Antenna
The antenna itself is an off-center fed vertical dipole made by flipping an electrical quarter wavelength of braid back over the outside of the coax
The Little Stick Antenna for 2 Meters, VE3VDC
Very compact, only a meter tall on 2 meters no ground radials needed fairly broad bandwidth
The Broadband Double-Bazooka
The increasing interest in usingthe coaxial dipole sometimescalled the Double-Bazooka an-tenna for its questionable in-creased bandwidth is disturbing
Building a double bazooka antenna
The double bazooka is a balanced antenna it is made of coax each branch of the antenna has 2 parts, the first part consists of a quarter-wave shorted stub made of coax

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
