Construct Your Very Own Bazooka Antenna With These Steps

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.

This device is effective because they can be mounted on a currently installed feed line, and the objects are armored with a capability to be twisted and installed in a car trunk. Their capacity to work as a similar product with a half wave wire helps a customer easily design numerous variations of this antenna. The wire is made by spinning a minimal quantity of electrical wavelengths with the coax outer layer.

The center lead molds half of the dipole, while the braids give shapes to its other half. The configuration of this wire makes them a device that produces a minimal quantity of obstructions that has a scope of 55-60 ohms. Plaits are the antenna highlighted features because they reduce the amount of radiation being emitted by a feed line, and making them short in size correlated to its other pieces.

The size is brought forth by the contact of the plaits and coax wires, and the braids found on the inner and outer part mixes to form the balun. The items required to produce a cable are the following, the specific length of heat deflating tube, coaxial, and the adaptor that could fit the radio. The procedure starts by removing the coax outer portion for the insertion of a top section, and followed by the flicking of the braided back over the covering till it ends at the lower mark.

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.

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.

Making a standalone version needs the snipping of the wires beneath the plaits to a specified length followed by its conjunction with the conductor. A placement of an optimum coupling to the feed lines and radio is the final procedure. Construction of this cable is followed by an optimum tuning.
