Manufactured an external antenna mount with the ability to rotate. The external antenna showed excellent results,more than doubling the speed and slightly increasing the signal strength. In my country house,the 4G network is overloaded,and DC-HSPA works very well.我看到一个excellent speed for this type of network of about 15MBps,veus 4 MBPS indoo without an external antenna. 我需要2 m of single-core copper wire 1.5mm。我把他们的cut pieces wire into the printout and soldered them,sometimes cooling the printout。 The coaxial wire is soldered to the inner core and the body)【the body braid is made of some metal covered with copper,it did not work to solder,I screwed it with a plastic screed.】 Outside the antenna,just in case the copper wire is not oxidized,painted with gray paint. 谢谢你为他们的工作的作者。
