3G USB modem antenna: To increase the signal level and, as a result, connection stability and speed, you can use a simple, cost-free method.
The test subject was the Beeline modem ZTE MF-622. You need a wire ~20 cm long, preferably copper (with or without a rubber braid, it doesn’t matter). We wrap several turns around the modem, the distance between the turns is 1 cm. We also need a CD or DVD disk, any unnecessary one, and after ironing it, bend it slightly as shown in the photo.
We point our improvised device in the direction where the operator’s tower is located and... voila.
Another way.
As you know, the 3G signal is not of good quality everywhere. This makes the Internet simply “stupid”, but there is a way to increase the signal. A regular saucepan and a USB extension cable will help with this. We connect your modem through an extension cord and put it in a regular saucepan or colander))), after these steps the signal will noticeably increase and be more stable. If you still manage to get him outside it will be just great and you can download the entire Internet xdddd)))
