How to Boost a Cell Signal With a Dish

by Marshal M. Rosenthal

The interior antenna in a cell phone cannot operate as efficiently as an external antenna. To enhance the cell phone's signal, add the parabolic properties of a dish as an external antenna. A few parts from a hobby store and a kitchen supply shop are all that is needed, as are a few tools most households already have on hand.

Step 1

Collapse the metal strainer. Place the strainer facedown on a work surface. Cut a hole through the center of the strainer's bottom with a portable drill.

Step 2

Place the N adapter plate faceup on the work surface. Heat up the soldering iron for four minutes. Insert an end of the copper wire into the center contact in the N adapter plate. Apply a drop of solder to the end of the copper wire to secure it inside the contact. Release the copper wire after 20 seconds have passed.

Step 3

Push the free end of the copper wire through the hole in the strainer. Press the sides of the N adapter plate against the strainer. Solder the sides of the N adapter plate to the strainer. Let the solder cool for two minutes. Unplug the soldering iron.

Step 4

Insert the "N" port on the Pigtail N adapter into the socket on the back of the N adapter plate. Pull the protective rubber cover off the antenna port on the cell phone with your fingers. Insert the Pigtail N adapter's antenna plug into the cell phone's antenna port.

Unfold the strainer so that it forms a dish shape. Aim the front of the strainer in the general direction of the cellular towers--if inside, toward a window or glass door, and if outside, toward the horizon.
