2 pieces 4G LTE TS9 connector antenna - signal amplifier for Huawei E8372, E5577, E5573, E5786, E8278, E8377, E5372, ZTE R216, MF920, MF90C

Type: 4G/3G
Frequency: 1900-2600 MHz
Antenna Peak Gain: 5 dBi
Connector Type: TS9
Impedance: 50 Ohms
voltage: 5V

Purchased at DouDou Digital Store

Review: Antenna showed negative gain in tests! I.e., the signal level, expressed in conventional units - "sticks", after connecting the antenna became lower for two items.
It is quite possible such an effect due to the fact that the test was carried out in the coverage area of the UMTS-900 and the antenna was not simply designed for these frequencies.

Куплена в магазине DouDou Digital Store

Отзыв: Антенна показала в тестах отрицательное усиление! Т.е., уровень сигнала, выраженный в условных единицах - "палках", после подключения антенны стал ниже на две черты.
Вполне возможно такой эффект из-за того, что тест проводился в зоне покрытия UMTS-900 и антенна просто не рассчитана на эти частоты.

Review: This antenna at least behave like an antenna, in an area with an unstable 3G signal level, it added 1 conventional unit (one "stick") in signal level and stabilized the connection.
While turning to 90°, it demonstrated the directivity, the signal level fell, as it should be. But the lie about the declared gain of 88 dBi can be easily divided by 10!
It should be noted that the test was carried out in the coverage area of the UMTS-900 and, according to the specifications declared by the manufacturer, the antenna covers the edge of these frequencies and may have low gain on them.

4G LTE MIMO external 88 dBi antenna inside
Отзыв: Эта антенна хоть вела себя как антенна, в местности с неустойчивым уровнем сигнала 3G, добавляла уровень сигнала 1 условную единицу (одну палку) и стабилизировала связь.
Показывала направленность, при повороте на 90°, уровень сигнала падал, как и должно быть.
Но враньё про заявленное усиление в 88 dBi можно смело делить на 10!
Надо отметить, что тест проводился в зоне покрытия UMTS-900 и, по заявленным производителем характеристикам, антенна эти частоты захватывает краем и может на них иметь низкое усиление.


Final analysis

4G LTE MIMO external 88 dBi. Final analysis
To conduct a "final analysis" of the 4G LTE MIMO external 88 dBi antenna, I placed the Huawei E5577 router in a metallized bag and tin box.
This was done to exclude the reception of a 3G (4G) signal on the internal antenna of the Huawei E5577 router.
The antenna worked, gave a good signal level, on 3G - a maximum.

Чтобы провести "окончательный анализ" антенны 4G LTE MIMO external 88 dBi, я поместил роутер Huawei E5577 в металлизированный пакет и жестяную коробку.
Это для того, чтобы исключить прием 3G(4G) сигнала на внутреннюю антенну роутера Huawei E5577.
Антенна работала, давала хороший уровень сигнала, на 3G - максимум.

This antenna gave the signal gain of 2 conventional units (two "sticks").
It allowed to get the the maximum out of 3G on the area with poor coverage.
4 megabits - speed limit according to the mobile tariff.


Доступна в магазинах

Отзыв: Эта антенна дала прирост уровня сигнала 2 условных единицы (две палки).
Она позволила выжать максимум из 3G на местности с плохим покрытием.
4 мегабита - ограничение по скорости по тарифному плану.
