Materials that are required:
|02 homemade phone 3g gsm booster antenna|
* 14,15 inch piece of iron wire. (Don’t use copper)
* A 2 piece connector block. (Used to extend electric cables)
* A small bolt and nut that fits through the whole of the “chocolate block.
* 32 feet of coax cable. (Don’t increasing the length of the cable, shortening it is okay thou)
* A piece of water pipe.
* A piece of plastic. (I used an ice-ream container)
Building the antenna GSM booster:
|03 homemade phone 3g gsm booster antenna|
Straiten the wire with pliers and bend it exactly in the center at a 90 degree angle. Measure 3.54 inches from the bend on both sides and bend inwards at 90 degrees. Bend the edges of the wire inwards on both sides again at 90 degrees 3.14 inches away from the last bend.

Insert the connector block to the ends of the wire and tighten it with a screw driver.
|05 homemade phone 3g gsm booster antenna|
Saw one side of the pipe in half and make a whole on the other side in the center. The whole should just be big enough for the bolt to go through. After placing the bolt inside the whole, insert the “chocolate block” on top and tighten with the nut.
Connecting the coax cable:

Strip the one end of the coax cable and separate the inner and outer wires. Connect the inner wires to one side of the “chocolate block” and the outer wires to the other side.
|07 homemade phone 3g gsm booster antenna|
Place the GSM antenna on your TV antenna pole facing the same direction and lead the cable into the house.
|08 homemade phone 3g gsm booster antenna|
Strip the other end of the coax cable and separate the wires inside again. This time you need to cut away the outer wires since you won’t need them. Take the piece of plastic and cut it in the shape you desire. Make a small hole on one end and stick the inner wire of the coax cable through.

You can wrap the whole thing in tape like I did if you’d like.

Simply place your modem on the piece of plastic or hold the plastic to the back of your phone to boost your signal strength.
My cell phone signal gets boosted to full bars and my GSM 3G modem gets at least one to two bars extra.
