This antenna is very easy to make from a piece of 50 ohm or 75 ohm coaxial cable

This is an off-center-fed sleeve dipole, made of 1/2'' CPVC and aluminum foil tape

This one is built with cheap carol RG-6,this coax has a single aluminum shield without the waterproofing glue

Probably worth the effort if you're looking for an all-purpose, performing dipole it is certainly more broadbanded

Bazooka GP vertical a omnidirectional antenna for the 40m

Bozooka for 40 meters, example for frequency 460/7.08x19.803 mts

The formula is 140.2 / fMhz = total length 99.06 / fMhz = length of the coaxial 20.57 / fMhz = length of each side of flat ribbon

Electrically it is very different to a conventional dipole it incorporates a balun

How to make a Bazooka for balanced output

The Bazooka has been one of my favorite portable antennas for years. It is easy to build, easy to handle and easy to transport

There is a Java Script calculation program from in which one enters only the desired frequency mid-band)and immediately receives the correct length as a solution

Measurements that successfully: Band: Coaxial length: 30m 9.77m 2.03m 30cm longer left to vote) 40m 13.99m 2.904m 30cm longer to vote 80m 26.77m 5.41m<

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

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 factor

Coaxial dipole formed from two 1/4 wave shorted end stubs

Constructed using coaxial cable elements of reducing their size by exploiting the Velocity Factor of the cable

The antenna is known as a double bazooka design and is very popular with radio amateurs who make it for 144-146mhz FM operations

The coaxial dipole antenna consists of a half-wavelength section of coax line with the shield opened a the center and feed line attached to the open ends of the shield

A typical, dipole antenna has bandwidth of about 50 to 100 KHz

This antenna can be cut for any operating frequency, from 160-meters down

This antenna consist of a half wavelength piece of coax RG58 with the shield split at the center and the feedline attache

The double-bazooka consists of 1/2 lambda of coaxial cable cut at its center or twice 1/4 lambda

The antenna works fine, designed for 28.5MHz it is broadband enough to cover the full 10m band

Just built another bazooka, this one for 40m,the bandwidth on this antenna has exceeded my expectations, i have the entire band below 2:1

The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun

The double bazooka dipole with one more bazooka match built into the feed line, the Triple Bazooka

The increasing interest in usingthe coaxial dipole sometimescalled the Double-Bazooka antenna for its questionable increased bandwidth is disturbing

With the feedline attached directly to the two open ends this acts as a half wave dipole

An aluminium version of the Vertical Bazooka design which was made from coax

Is an off-center fed vertical dipole made by flipping an electrical quarter wavelength of braid back over the outside of the coax

Programma caculator for bazooka antenna,with measurements already calculated for frequeze used by radio amateurs

The calculation of the popular double bazooka antenna is easier than you can imagine
