5 Dbi GSM Rubber Duck Antenna

A “rubber duck antenna” is a type of omnidirectional antenna commonly used in portable radios and walkie-talkies.
A rubber duck antenna is a short, flexible antenna made of rubber or similar material, usually about 6 to 10 inches in length. It is designed to be compact and easy to carry, while still providing decent performance for short-range communications.
Rubber duck antennas are omnidirectional, meaning they transmit and receive radio signals in all directions equally, making them ideal for applications where you need to communicate with multiple parties in different directions. However, their range is limited compared to larger antennas with more directional capabilities.
Overall, rubber duck antennas are a good choice for portable radios and walkie-talkies used in situations where portability and ease of use are more important than long-range performance.
Frequency range: Typically covers the GSM frequency bands of 900 MHz and 1800 MHz.
Gain: 5 dBi (decibels relative to an isotropic radiator), which is a measure of the antenna’s ability to focus radiation in a specific direction compared to an ideal omnidirectional antenna.
Impedance: 50 ohms, which is the standard impedance used for most RF (radio frequency) systems.
Connector type: SMA (SubMiniature version A) or RP-SMA (Reverse Polarity SMA) connector, which is commonly used in wireless applications.
Polarization: Vertical polarization, which means that the antenna radiates and receives signals in a vertical direction.
Radiation pattern: Omnidirectional, which means that the antenna radiates and receives signals in all directions equally.
Dimensions: The length of the antenna is typically around 15cm, with a diameter of around 1cm.
Material: The antenna is usually made of a flexible rubber material, which makes it durable and able to withstand bending and twisting.
