Dear friends, be careful when installing the antenna, but don’t break the antenna port of the network card
Please take a picture of the antenna interface so that we can deliver the goods, please contact customer service if you are not sure
Generally, wireless routers have 2 antenna interfaces, so it is recommended that you buy two for better results. For shipping issues, we do not provide free shipping, and the shipping prices are real, sell this In order to increase Taobao’s sales, if you don’t send a certain number of items every day, you won’t be able to get a lower express delivery price. In particular, this product is really not profitable. At the same time, you must be prepared to use an external antenna. It is not that the signal can become stronger and stronger by plugging in the antenna. The antenna itself is not so magical. Mainly suitable for indoor signal is not good, put the antenna outdoors to transmit the signal indoors. This product will never accept bad reviews because you suspect that the signal does not meet the requirements. If you shop in good faith, you can apply for return processing if you are not satisfied with it. It is recommended that you purchase return insurance.
Once again, we will not refund the shipping cost if the product is returned.(I suggest you buy freight insurance)Because we send expressIt also costs money, so you can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t serve it wholeheartedly and you still lose the freight!

Camp, I wish you a happy shopping! peace brings money
5m extension cable, magnetic base:The buyer puts the antennaPlace it in a window or other place with strong signal receptionpoint.
(Can increase the ability to receive signals)The antenna is only to assist in receiving the signal, it does not mean that the signal will not change to the signal when the antenna is plugged in. The effect of the antenna is also not felt in the place where the signal is very good or poor.

If you are not sure, please contact customer service Note:Do not use force when plugging or unplugging the antenna to avoid damaging the network card!
In the mountains and in the desert, what should I do if the signal reception is poor? This is the helper! ! !
Dear, if the local 3G, 4G signal is not good, what?
do? The network card signal amplifier will help you~~
Applicable equipment type: Huawei ZTE CRC9 4G antenna(The wireless network card has 2 types of connectors, one is CRC9 connector and the other is TS9 connector)
The difference between the two is that the aperture of the CRC9 is 2mm, and the aperture of the TS-9 is 2.5mm. Please confirm it clearly. Otherwise, the wrong connector is bought, and the return shipping fee will be borne by the buyer.

About a few common questions
1、Why is there unstable situation after normal connection?
Answer: After the normal connection, the installation angle and height of the antenna are fixed, and there will be no physical changes. Unstable conditions may occur at the joints of the feeder, for example, contact resistance increases due to long-term oxidation. Also, the operating conditions of the equipment, such as heat generation, DC power supply waveforms, etc. Especially important is the impact of weather. Through our practice, we have found that rain and heavy snow have an impact on the signal.
2. Is the gain value marked on your antenna real?
Answer: This question is also of concern to my friends. The concept of gain itself is relative. In theory, the explanation is a bit more complicated. Both professional testing and amateur testing are done relative to a set standard. We chose two benchmarks for gain testing. One is a half-wave period, and the other is a finalized antenna. Through a series of comparative tests, the gain value is obtained. Of course, this value cannot be compared with a professional test environment, and there must be a certain error, but this error is not necessarily exaggerated, or may be reduced. For example, the gain of a 32-slot waveguide omnidirectional antenna, our highest mark is 18 decibels, because this is the result of our test. The finished notch antenna can be marked with 21 decibels.
3.How many types of antennas are there? What is the role of each?
Answer: There are generally two types of antennas, namely directional antennas and omnidirectional antennas. As the name implies, a directional antenna refers to transmitting a signal in a specific direction, while an omnidirectional antenna transmits a signal to the surroundings. Generally, if it is a point-to-point transmission, a directional antenna is used; if it is a point-to-multipoint transmission, an omnidirectional antenna is used.
4. Should the antenna be installed indoors or outdoors?
Answer: This should be treated differently according to the specific usage and environment. The specific installation location can be understood in detail with us at the time of purchase.But generally speaking, the effect is better if the antenna is placed outdoors.
Shipping Instructions:
All the goods photographed before 18:00 will be sent out on the same day. If the time is exceeded, we will try our best to arrange the delivery. It is really impossible to deliver the goods the next morning. If there is a shortage of goods, there will be a slight delay, please forgive me, it is normal for a wide variety of goods to be out of stock.
