A helical antenna is constructed from a wire that is wound to form a coil or a helix. Here's how to build one wireless booster :
1. Prepare materials and equipment needed. First get the standard cable households with diameter 12 gauge or 14 gauge. Diameter of which is not an important factor in the performance of the main antenna. However, because the antenna must be placed outside the home, he must be strong and heavy as the size of which is above. Length must be in accordance with the length of the field around the antenna. In addition, a PVC pipe with a size of 40 cm diameter and 40mm will be used to keep out the wind with a wire surounded. Other materials that must be purchased from the store is a metal mesh to the ground plate; Impedance stub consisting of a copper foil strip with a triangular-shaped dimensions 17mm and 71mm in height of a male coaxial cable, screws for the antenna to the ground plate; the end of a PVC a hat that will cover in accordance with the size of pipe, a plug cap that will be used to cover the end of the pipe, and PVC cement secukupnya. There screwdrivers, an electric drill, and soldering iron in the reach during the set up.
2. Mark the PVC pipe. On PVC pipe, across the surface pipe PVC with cable on the pipe. Make sure the coil the same distance across the surface of the PVC pipe that is 3cm. Make sure that the Helical antenna is optimized, consider to make a circle approximately 12 on the pipe.
3. Wind the wire correctly. Wrap the wiring around the PVC pipe making sure you follow the markings you previously made. Do not forget to set aside enough wiring off the end to make room for a secure attachment of the copper foil. Solder the wire end onto the narrow tip of the copper foil to join them together.
4. Do the finishing touches. With the use of an electric drill, make a hole in the end cap for the connector's attachment. Afterwards, attach the end cap onto the ground plate using screws. Put some PVC cement both on the end cap and the pipe and securely slip the pipe in. Make sure that the copper foil stub is sticking out of the end cap's drilled hole for the connector. Attach the copper foil to the connector's center pin with the use of a soldering iron. Afterwards you should screw the whole structure to the ground plate.
5. Helical antenna can be made to work with both the axial or normal mode. A helical antenna will work in normal mode when you have a dimension smaller than the actual wavelength. Meanwhile, if the dimensions of the antenna has a larger signal from the signal wavelength, it will be working in the axial mode. A spiral antenna in axial mode will be far better in performance and reliable in capturing a variety of signals as compared to the normal mode
