A 2 dBi Rubber Duck GSM antenna is a type of antenna used for wireless communication devices that operate on GSM (Global System for Mobile Communications) networks.
The “2 dBi” refers to the antenna’s gain, which is a measure of the antenna’s ability to direct or concentrate radio frequency energy in a specific direction. The higher the gain, the more directional the antenna is. A 2 dBi antenna is relatively low gain and may be used for short-range communication.
The “Rubber Duck” refers to the antenna’s form factor, which is often a flexible rubber-coated tube that can be easily bent or curved. This type of antenna is commonly used in applications where space is limited or where the antenna needs to be mounted on a curved or irregular surface.
Overall, a 2 dBi Rubber Duck GSM antenna is a small, flexible antenna that can be used for short-range wireless communication on GSM networks
