Start Constructing Your Own Bazooka Antenna With These Methods

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 conjunction of an open edge allows them to assume the part of a half wave dipole that can be disintegrated in different divisions to let a frequency flow orderly. Bazooka antenna is separately connected to flat surfaces that withstands hindrances and have a multiple band cable function after an optimum tuning. The wire is a cheaper substitute, considering a coil and ground radial is not necessary.

These products are efficient in a way they can be integrated in a previous feed line and they can be twisted and placed in car trunks. Their capability to perform closely similar to a half wave antenna easily constructs different variations of this device. The wire is built by flicking a quarter of an electrical wavelength located at the superficial part of a coax.

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.

Their short size is due to the interaction of its coaxial with the plaits, and the braids on the outer part combines with the inner ones to produce the balun. The materials needed to form the antenna is composed of a certain length of coax, heat deflating tube, and a connector that fits the radio. The construction starts with the removal of coax outer section for the top section to be inserted, and then the braided back is flipped over the covering until it reaches the lowest part.

The braid and uppermost portion is snipped to a specified size after the spin. A calculation is done to reach the particular length of coaxial to be sliced, and this makes the cover. A client should remember that they should not make cuts in the plaits.

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.

Firmly grab the plaits to the cover and position them in the lowest portions by using an adhesive tape, and after the conjunction, snip it to a specified length. Cut the tubes into separate pieces to defend the braids and feed points, and place the wires in position with a hair dryer or glue gun. The emergency kind of these antennas is designed from the extra coaxial wires.

If they would want to build a version that could stand alone, then it would be better to cut a sufficient length of cables under the braid and connect it to its conductor afterwards. The installation of an efficient connector to the feed line and radio comes last. Once the composition of this antenna is ready, tuning comes afterwards.
