How to Create Modem Antenna Signal Amplifier

Signal Amplifier
Means the cause of slow internet at home is a signal. Hmmm ... a few ways to increase the signal of an additional antenna, external antennas and repeaters. In this paper the author discusses only antenna that can be made yourself with an affordable cost and effort.
Many additional antennas are sold on the internet with prices varied from $ 4 to above $ 11, but reviews from forums that the research authors, the increase is less significant. So the authors discouraged to buy an antenna like that.
Antenna Type your HP
On some HP and a modem that uses an internal antenna (antenna not punch out) there was a jack sockets for an external antenna. Socket is closed by a rubber cover which can be opened in a way taken out. Try looking in the suburbs or the back of the HP / modem. If you've met open and see a small round yellow socket.
Some HP (mainly in the form of flip / fold) have a protruding antenna, and some can be opened by twisting. Perhaps the point that can be replaced with a larger.
There are also examples of HP with internal antenna but without the necessary sockets for antennas externar. An example is the Nokia 6585.

Copper winding wire
This is the most simple and fairly inexpensive. Take copper wire and wrap 30-50 cm 2-5 times in the last HP Peel the rest of the cable about 10 cm and the direction it onto your HP. The benefits that can improve signal reception up to 2 bar even 3 bars. Be careful with the end of the cable which can scratch the casing / display of your HP.
This method can be varied with a soldering tip of the cable with the antenna socket and antenna socket hubingkan with you as mentioned above. For the HP without a socket it can not be done.
The length of the optimal antenna for GSM 900 is 33.3 cm while for the GSM 1800 is 16.7 cm. The formula is the length of antenna = C / Frequency; with C is the speed of light = 300,000,000 m / s.
If true, the reinforcement signal obtained can reach 2 bars (scale 5) either GSM or 3G signals.

Paper Clips and Hanger Antenna
This is a free way to increase your cell phone reception but with little export. The instrument used is a clip, pointed pliers and duct tape. First of all abillah sebuahklip paper, then straighten the ends with pliers, then bend the clip ends 0.5 cm was 90 degrees on the clip (as a plug against the socket HP). Attach the end of the clip on your cell phone antenna connector and the clip on the body selotiplah HP. For more details, see the picture.
This only can improve signal reception as much as 1 bar (Scale 5).
As a variation you can use a clothes hanger made of copper instead of clips. Bigger = better.

Tesla Coil Antenna
By utilizing the principle of tesla coil, you can maximize your cell phone signal reception. This trick can only be used in HP that have a protruding antenna / external. The material used is a thin wire (such as binding yanguntuk cable) and isolation. Wrap the wire on your cell phone antenna, 5-7 coil winding insulation is enough then. Voila. Check your cell phone signal reception.
The author does not know the amount of reinforcement for this type of signal, from googling on the internet, how it can improve the signal to 2 Bar (scale 5).

Old Radio Antenna
Your old radio antenna that has been unused signals can be used to strengthen your HP. You do this by connecting the antenna to your cell phone antenna connector. Better yet, if you create a socket to attach the antenna to your cell phone. This method can improve GSM signal and 1 bar of 3G signal as much as 2 Bar (Scale 5).

Soda Can Cradle
This method is very easy but can not be used to send SMS / make calls but to avoid miss-miscall or SMS. Materials needed are cans of soda. Cut the soda cans lengthwise (split 2) and put your cell phone inside your cell phone signal reception would be increased at least 2 bars on a scale of 5.
