Huawei EC189 EC1261 EC1260 network card has an external antenna. The interface is 2.5mm in the size of the earphone jack. I don’t know if it is available. You can plug in a 2.5 earphone at home. If you can plug it in, the antenna will definitely work.
(There are two types of products, straight and curved. Antennas are placed at different angles. If you need to specify straight or curved, please take a message. The shopkeeper who does not leave a message will be shipped randomly by default.)There are two types of straight and bent shapes, and they cannot be bent freely. Please pay attention!

The antenna is affected by several factors
1. Your local signal environment
2. Equipment will also affect. Different devices sometimes have different effects.
In some special environments, if your network card signal is not good. Connecting an external antenna rod can effectively strengthen your signal. Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t ask me how much signal can be strengthened, I can only say that it is definitely better than not connecting an external antenna rod. The signal must be strong!
Many people like to make their own diy antennas and make so-called improved antennas. In terms of signal loss and interference shielding, these cannot be handled perfectly, so trust the professional design of major manufacturers!
The antenna is the same size as a pen, it is an omnidirectional antenna, and the gain ranges from 2-5DB
The 10DB omnidirectional antenna is very full length, and the 9DB omnidirectional antenna is about 45CM long More than 1M of 12DB(Some netizens said that it can be DIY to 12DB, and the antenna rod must be at least 1 meter long)
It is now recognized that the better directional antenna is the 14DB panel antenna(Note: It is a flat antenna)Generally speaking, there are omnidirectional antennas up to 12DB, but the precision requirements of the manufacturing process are quite high. If it is not for a famous manufacturer, it is impossible to produce an omnidirectional antenna above 12DB, but an antenna with a high gain may not have a strong signal, because the vertical angle of the radiation of a high-gain antenna is very small, and 12DB is only about 10°. If your transmitting point and receiving point are not on the same horizontal line, the signal will become very poor, even much worse than that of a low-gain antenna. A slight change in the antenna will also cause a large change in the signal coverage angle. So friends who buy high-gain antennas, please figure out these issues first. High-gain antenna, standing wave below 1.5, the horizontal lobe width is greater than 60 degrees, and the vertical direction is about 20°. Otherwise it doesn''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t make sense
