How long is a double bazooka antenna?
How long is a double bazooka antenna?
10M – 16′ ft.
A double bazooka beats a dipole in bandwidth and performance any day. Approx. Length : 10M – 16′ ft.
How does a bazooka antenna work?
Its broadband characteristic makes it ideal for 80 meters and 10 meters. The Bazooka antenna consists of a half-wavelength of coaxial line with the outer conductor opened at the center and the feedline connected to the open ends. The outside of the coax and the ladder line operate as a half-wave dipole.
What is a double bazooka?
A DOUBLE BAZOOKA antenna is an extremely broad banded Half Wave Antenna which can operate efficiently across an entire Ham band with little change to the SWR. The BAZOOKA antenna design was developed by the staff of M.I.T. in the early 1940’s for use by the US. Government as a radar antenna.
What is the strongest CB antenna?
Fiberglass antennas are usually the best choice for 4×4 and off-road drivers. They’re the most durable type of antenna and hold up best to the rigors and abuse of off-road use.
How does a double bazooka antenna work?
The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends. Do not break the center conductor.
What is a cobweb antenna?
The Cobweb antenna is a antenna which is easy and fast to install for portable operations, designed by G3TPW. The Cobweb antenna covers the five upper shortwave bands 20, 17, 15, 12 and 10m. One common balun feeds five dipoles which are folded in a roughly square shape, only one feedline is required.
How do you calculate the frequency of a bazooka antenna?
For the full length of the antenna enter the following formula into a calculator. The average center frequency of 40 meters is 7.150MHz, so this is the frequency we will stick with to build our 40 meter Bazooka. The simple formula is 460 ÷ 7.150 = 64.335664.
Are there any bazooka antennas that don’t work?
There have been many Bazooka antennas built that just did not work right. They could not get a low SWR. It was not broadbanded…..etc.. The reason in many cases is the builder did not convert the number in the calculator that is after the decimal point.
How do you build a vertical bazooka?
The only things you need to build a Vertical Bazooka are a length of coax, a connector to fit your radio and a length of heat shrinkable tubing. All these parts should be readily available from your local electronics parts or ham radio stores.
Can I use 75 ohm coax with my bazooka?
If you decide you want to use a 75 ohm type of coax to build your Bazooka, just consider these facts before you make the decision. 75 ohm coax will not make the Bazooka perform better. Using the low grade 75 ohm RG-59 coax will not perform as well as a basic wire dipole.
