Construct Your Personal Bazooka Antenna With This Method

By Timothy White


The mono band antenna does not require the assistance of balun, and they are made from coaxial wires that could emit fifty ohms. The shield split is located in the middle, and their feed lines are connected to open edges. The client is advised not to break the conductor located in the center.

The line direct connection to the open edges serves as the half wave duple, and they can be cut into pieces to give way for the frequencies to function. A bazooka antenna is freely attached to a plane surface that handles limitations, and an efficient tuner could make them work as a multi band cable. These wire are cheap products wherein coils and ground radials are not necessary.

The product can also be associated in a previously installed feed line, thus making them efficient, and these materials are twistable that they can be positioned in car trunks. They are equipped with the ability to function similarly to the half wave antennas that a client could easily build various types of this tool. Their wires are constructed by casting a little amount of electrical wavelengths located at the coaxial exterior layer.

The lead found at the center of its coax shapes half of the dipole and the other half is supplied by the plaits. This composition makes a cable a device with a low pattern of radiation and an obstruction of 55-60 ohms. The braids are the main feature, since they help in reducing the amount of feed line radiation, and they end up shorter in size compared to other elements.

The short composition is brought by the synergy of the coaxial wires with the braids, and the plaits seen on the interior and exterior sections are combined to shape the balun. Materials necessary in producing a cable include the particular length of coaxial and heat deflating tubes, and the coupling compatible with the radio. The process of making the antenna starts by detaching the coax exterior section for the upper layer to be infused, and followed by spinning the braided back on the cover until it could reach the ends.

The plait and its top section should be sliced to a specific length, after flicking it. To make the outer covering, start by calculating the specified part and slice the coaxial surrounding section. The customer is reminded not to slice the braid or a section of it.

The cutting of the coaxial that could produce a lengthwise slit in the jacket follows, and the removal of these sections exposes a braid. Afterwards, the plait needs to be flipped, and followed by gently removing the braid from the insulation and move it to the inner conductor. Grab two inches aloft the uncovered section and force it against the coax found in the short sections, after letting it loose.

Hold the braid tightly over the jacket and place a tape to keep it in position at the bottom part, and trimming the plait to a particular length follows. Cut a piece of a tube that serves as a covering for the plaits and feed point, and a blow dryer or a glue gun can help in positioning the wires in place. The emergency version of this cable is constructed from the extra remaining cables of the coaxial.

In building a standalone model, it is advised to cut the enough length of wires underneath the plait and have it connected to its conductor. The installment of an effective adapter to the radio and feed line is the last step. Tuning follows after the construction of this antenna.
