Cheapest Mobile signal booster external antenna

There are some pretty signal boosters available in market which can only boost or amplify weak signal. But these products can’t bring unavailable towers.

You can buy external antenna for this purpose but this antenna is a cheap replacement of that. You can use a stick aerial for this purpose and I’ve tested that it’s better than that.

The setup in my house brought international signals from 5KM far tower. You need to locate the external antenna connecting point in your mobile.

In most mobiles, it’s below battery battery compartment or in backside of mobile. Connect an aerial antenna with it and be sure it’s ground isolated. If the antenna is somehow connected to ground, it will not function properly. place the antenna in outdoor and use a wire to bring the connection to room.

Note: Provide a cover on antenna as you are placing it outdoor, it may get electrical charge from environment which is harmful for your phone.

    August 11th, 2011 at 1:28 pmThe approach I told will work in any GSM/CDMA phones and also in modems. You need to open the cover and find an antenna connector in the circuit board. The connector looks like the golden color tip I shown. With help of an soldering expert, solder a thin wire to the mid pin of the antenna connector and then attach an stick antenna there and keep the antenna untouched to ground, or anything. Even cover the whole antenna by dry plastic cover. You can use cellotapes too.

    okay…so whats the opening with the rubber cover at the side? i thought that maybe if we connect a copper wire to it and again connect the wire with an antenna might boost the signal…haha :D

    August 18th, 2011 at 3:51 pmYeah sure. 99% chance the antenna connector is beneath the rubber cap.
