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
Regarding the shipping cost, we do not provide free shipping. The shipping price is real. Selling this product is purely in order to increase Taobao sales. If you do not send a certain number of items every day, you will not be able to get a lower express delivery price. In particular, this product is really not profitable, and at the same time, you must be prepared to use an external antenna. It is not that the signal can become stronger or 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 freight if you return the goods,（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! Small scripture
Camp, I wish you a happy shopping! peace brings money
（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.

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 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, directional antennas and omnidirectional antennas. As the name implies, directional antennas are used to transmit signals in a specific direction, while omnidirectional antennas are used to transmit signals 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, it is better to put the antenna outdoors.
The length of this antenna is 19 cm
