While mobile phone providers are continually putting up new towers for more widespread coverage, the reality is that there are still a great number of users who are unable to pick up a good signal on a regular basis. Before deciding to purchase an expensive factory-made cell booster, you may want to try a do-it-yourself solution first.
Boosters in Your Kitchen
Those handy-dandy ties for your garbage bags contain a tiny metal wire called Tesla. Tesla is the wire used in many antennas, and it can be wrapped around your cell phone's antenna space to increase signal strength. Open a drawer and pull out a paper clip. See what happens when you gently place one end of the straightened paper clip into the internal antenna slot. The paper clip or Tesla wire can be secured with electric or clear tape.
Open Your Closet
Grab a pair of needle-nose pliers for cutting a wire hanger into an antenna-sized booster. By carefully sticking the end of your newly created antenna into the SIM card slot or antenna hole of your phone, you should see an increase in your phone's signal bars. If this works, duct tape can be used to keep the wire in place.
Build Your Booster
Probably the most effective means of making your own cell signal booster is the tin-can method described in this video: http://www.metacafe.com/watch/750707/how_to_make_a_cell_phone_antenna_under_5_minutes/. This booster takes less than five minutes to build and requires only a few simple items that you may already have in your garage or basement, such as solder and a soldering gun, copper wire or tape, pliers and two tin cans. Although holding your phone with a coffee can pointed in the air may seem a bit far-out, it sure beats not having a working phone in a desperate situation.
