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 attachment of the open ends plays the role of a half wave duple, which can be separated into various sections to allow the frequencies to work properly. The bazooka antenna is independently connected to a leveled surface that could endure restrictions and the multi band cable only functions after an effective tuning. This cable is an inexpensive substitute, since ground radials and coils are not needed.

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.

A center lead gives forms half of the duple while the other half is formed by a plait. The composition of these cable make them a product that could generate a low amount of impedance that ranges from 55-60 ohms. Braids are the product main highlights, considering they lessened the volume of radiation released by the feed line and that makes them shorter in size in comparison to other parts.

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.

After the flipping, the braid and the upper section is cut to a certain length. The construction of the outer covering starts by measuring certain and cut the parts surrounding the coax. The client is advised not to make any mistakes by cutting a section of a braid.

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.

Tightly hold the plaits over the covering and place an adhesive tape to place it in place at the lowest portion, and trim it to a specific length. Get the tube and cut it into pieces to serve as the protection for the feed point and plaits, and position the wires with a glue gun or hair dryer. Emergency models of this product is built from the remaining wires from the coax.

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.
