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 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.

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 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.

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.

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.
