Teleten 2 PCS-2 DBI SMA MALE GSM ANTENNA FOR POS MACHINE ROUTER Network Interface Card Antenna Amplifier

A 2 dBi Rubber Duct 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 Duct" 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 Duct GSM antenna is a small, flexible antenna that can be used for short-range wireless communication on GSM networks. The 2 dBi Rubber Duct GSM antenna is a small, flexible antenna designed for short-range wireless communication on GSM networks. It has a gain of 2 dBi and a rubber-coated tube form factor that is durable and can be easily mounted on a curved or irregular surface. The antenna is lightweight, compact, and has an SMA connector for easy installation and compatibility with a variety of devices. It is an ideal solution for applications where space and weight are at a premium.
