865MHz Helium Frequency 5dBi Rubber Duck Antenna With SMA Male Movable Connector

865MHz: This indicates the frequency at which the antenna is designed to operate effectively. 865 MHz is commonly used in certain radio communication applications, including some types of RFID systems.

Helium Frequency: This could refer to a specific frequency range associated with Helium networks, such as those used in Helium (LoRaWAN) networks for IoT applications. In Helium networks, 865 MHz is within the ISM (Industrial, Scientific, and Medical) band used in some regions.

5dBi: This is the gain of the antenna, measured in decibels relative to an isotropic radiator (dBi). A 5dBi gain means the antenna is relatively efficient at focusing energy in a specific direction, which can help improve signal strength and range.

Rubber Duck Antenna: This is a type of antenna that is typically flexible and durable, often used for its ruggedness and ease of use. The "rubber duck" design is a popular choice for many portable and handheld devices.

SMA Male Movable Connector: This refers to the type of connector on the antenna. An SMA (SubMiniature version A) male connector is a common type used in RF applications. The "movable" aspect suggests that the connector might be adjustable or rotatable, allowing for better positioning and alignment.
