In poor network areas, there are communication barriers due to the variation of signal strengths and therefore sometimes the best way to complete your call is to create your own homemade cell phone signal booster. There are other cell phone signal booster on the market, but some of these are less efficient as compared to the manually home made. There is also something to be said about the raw satisfaction that can be derived from making something with your own two hands… and then it’s actually useful to boot!

Here is how it goes

Before proceeding, it is important to note that any homemade signal booster has an assumption that the experiment may be more efficient than the available boosters or less effective due to some configuration and implementation strategies and there are no guarantees that your cell phone reception will be improved in any way. Before resorting to a homemade cell phone signal booster, you should look into other avenues like commercially available signal boosters, different mobile phones, or different service providers and the area span.

Make a coffee can signal booster

This is how to come up with an amazing signal booster using a metal coffee can.

  1. Get two empty metal coffee cans approximately 13 ounces in size.
  2. Get other materials needed like a can opener, solder, a soldering iron, antenna connector, and a “pigtail” connector.
  3. Remove the bottom from one of the cans using a can opener.
  4. Solder the two cans together to form a long cylinder. Copper tape is a suitable alternative to solder too.
  5. Cut a hole approximately 97 mm up from the closed end of the cylinder.
  6. Insert short length of copper hire into the receptacle of the antenna holder and solder in place.
  7. Attach antenna holder to the hole you cut in the can, securing in place with a nut. The copper wire should be on the inside of the can.
  8. Attach pigtail connector to antenna connector.
  9. Remove rubber cover from rear of phone, under which should be a port for an external antenna.
  10. Plug pigtail connector into external antenna jack on phone.
  11. Aim the open end of the can toward the closest compatible cell tower.

Extend the External Antenna

To his knowledge, this will only work with cell phones that have external stubby antennas, so if your phone has an internal antenna, it might not work. That said, many cell phones usually have a rubber-covered opening near the back where you can attach an external antenna. This is becoming less common with advanced smartphones and feature phones, so your mileage may vary.

Caution must be taken during this experiment because irreversible damage may be caused and hence leading to loss to you.

Improving Your Reception

While there is a chance that one of the methods described above might help with the problems you are having, they are not the best solutions for most situations and don’t take care of the cause of the problems you are experiencing. Typically, there are several reasons why your cell phone reception may be poor, but most commonly it is because of the inhibiting features of walls and other structures that may block the incoming signal. This experiment can also be used as a booster to bluetooth technology hence increasing the speed of data transfer.

It is also noteworthy than certain phones from certain manufacturers are known to have better reception than others. Some cell phone networks may also have better coverage in certain areas than others; consider getting new equipment or changing to a provider with better reception in the area(s) where you use your phone the most.
