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.

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.

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.

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.

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.
