I got the antenna. Order, to the final point in St. Petersburg reached 49 days. Track number was tracked only on China territory. With native antennas of the router, the number of divisions of the signal can be seen on 5 photos, with the antenna that was installed, in the end it turned out the same,,,, To seller and manufacturer thank you very much!!!.

The difference is not noticeable, I test with the antenna and without well can slightly higher the speed became the most simple antenna ordered if the Internet is strengthened palpably then the largest antenna

The simplest antenna, it was possible to do it yourself. But for such a price, in scrap. Again, connectors, wire, box. In general, normally, much, in the sense of signal gain, do not count.

It's took almost 33 days to reach. Product was accurate as described. Didn't use it yet, so can't tell about the product quality or its working condition. Hope all will goes ok. Thanks.

According to the description, connected to a Huawei B525s-65a 4G modem/router, the gain is low but exists. At this price it is worth the cost of trying!
