How to Build You Own Cell Phone Antenna
Cellular phones are quickly becoming the primary way people are communicating in today's fast-paced society. A mobile phone's reception is absolutely essential when so many people are using cell phones as their primary, and sometimes only, phone line. When a phone does not keep a reliably strong signal, the problem most likely lies in the quality of the antenna. Interestingly, many cell phone companies will not easily replace antennas without charging a significant price. Luckily, building your own cell phone antenna can be a quick and easy solution to this dilemma.
Things You'll Need
- Electrical wire
- Large screw
- Needle-nose pliers
- Straight-edged razor
- Electrical tape or duct tape
Unravel and measure at least 16 cm of your electrical wire on a table and, using a pen, mark the 16 cm point. With needle-nose pliers, cut the wire at this mark. Electrical tape or a small piece of duct tape can be used to cover one end so that bare wire is not exposed where you antenna's top will be.
Strip the rubber covering from slightly more than 1 cm at the other end of the wire with your straight-edge razor. Use caution not to cut the wire itself when you are stripping. This will be the portion of the wire that will be inserted into your mobile phone.
Wrap the center portion of the wire around a small screw at least five times. The curvature of the wire increases the antenna's performance by attracting a stronger signal. Carefully remove the screw from the wire, so that the antenna will be left with a spiral appearance in its midsection.
Insert the stripped end of your antenna wire into the external antenna opening of your phone. This opening is usually discreetly covered by a small rubber flap that will blend into the back or side of your cell phone. Carefully press the rubber cover back into place to securing the wire. Your bars should have increased significantly with your new antenna.
