Apps like CellMapper can show you the signal you're receiving on your phone. Get down below -110dBm and it's definitely a weak signal below -120dBm and you'll have trouble holding onto any signal at all. A number higher than about -90dBm (like -80 or -70) is a strong signal. Where your phone shows bars, wireless industry folks measure signal in -dBm. Do You Need a Cellular Booster?īoosters help the most when you have weak, but not absolutely no signal. Cheaper boosters sold on Amazon often aren't FCC-certified, which means they can cause trouble with surrounding cell sites and networks. That's why you need to stick with boosters from the big four companies: Cel-Fi, HiBoost, SureCall, and weBoost. Booster makers have to use various tricks to detect the best signal from surrounding towers and then amplify the signal without messing up the carriers' systems. Instead of relying on the tiny antenna in your phone, they capture cellular signal using a large antenna in your window or outside your house (or car), then pass that signal through a device that cleans and amplifies it, and out through a rebroadcaster inside your home. The basic principle behind signal boosters is simple: A big antenna is better than a small one. If you have weak or no cellular signal in your home, a cellular signal booster can really help. Moreover, with any questions regarding our devices you can turn to our customer support team.Now that many of us are working from home, cellular dead zones aren't just annoying, they're mission-critical. To choose the most appropriate model, we offer you to use our special Search form. All signal boosters that you can find in our catalogue meet the requirements of CE and RoHS certificates and are absolutely safe. If you don’t want to take such a risk and you prefer to purchase a cell signal repeater, we are here to help you. Though it may sound like a good idea to build a homemade signal booster, it can be rather challenging and, in some cases, even dangerous (as you need to work with bare wires). To make your homemade mechanism work, put this piece of plastic under your modem or place it on the back side of your cellular phone. To make this construction more reliable, use tape.Įverything is almost ready. Punch a small hole on one side of a piece of plastic (you can choose its shape on your own) and put the inner wire in it. You can put aside the external wire as we don’t need it anymore. Now its turn to take the second end of the coaxial cable and divide the wires. So, your GSM antenna is ready and now you need to place it on your TV antenna (don’t forget that you should place it in the same direction) and the cable should be put into the house. The inner wire should be connected to one side of the block, while the outer wire should be connected to another. Stripping one cable end, isolate the inner wire from the outer one. The next task for you is connecting a coaxial cable. Place your antenna on it and use a nut to fix a construction. The size of the hole should let the bolt go through it. Sawing one side of the pipe by half, do a hole in the center on the opposite side. Pay attention that the edges of the wire are bent at 90° inwards as well and these bends should be made at a distance of 8 cm from the previous ones.įirst connector block should be installed on the ends of our future antenna. Then measure 9 cm from the center to both sides and bend the wire inwards once again at 90°. Then, bend it in the center to form an angle of 90°. First of all, you need to straighten the wire (it is recommended to use pliers). Below you will see a list of all the necessary parts: If you want to make such a booster, you need to find all the elements of your future mechanism. This unique mechanism will help you to get over cellular signal problems at home, improving the quality of the signal that you have. Have you ever thought about a necessity to improve your cell signal? If you are fond of doing different things yourself, you may definitely like an idea to build your homemade cell phone signal booster.
