## **Delta 19** 

High Gain 8.5 dBi 2.4 GHz 19mm Stubby Wi-Fi Bluetooth Antenna 

## **Key Features** 

- Supports 2.4 GHz Wi-Fi 4/5/6 

- Supports Bluetooth / Zigbee / ISM 2450 / IEEE 802.15.4 Bands 

- Miniature Covert 19 mm length 

- 5/8 wave design 

- High gain of 8.5 dBi at 2.4 GHz frequency 

## **General Description** 

The Delta 19 is the smallest available, direct connect 2.4 GHz stubby antenna. The antenna is ideally suited for covert situations where limiting antenna size is a critical consideration. 

## **Additional Considerations** 

- Omni-directional Radiation 

Despite its small size, the Delta 19 achieves a high gain of 8.5 dBi, providing a stronger and more reliable Wi-Fi signal, particularly in areas with weaker signals. Its compact size makes it a convenient option for portable devices and where space is limited, without compromising on signal strength. 

The antenna is available with the SMA male and the Reverse Polarity (RP) SMA male connectors. The Delta 19 is commonly used with Wi-Fi, Bluetooth and Zigbee applications.

**NOTE:** For each frequency band, Siretta provides a traffic light indication to show the suitability of the antenna for use at that frequency band. Determination of exactly what makes an antenna good or bad at any frequency is subjective. 

The view presented is that of Siretta’s engineering team having taken into account the efficiency and VSWR measurements. The end user is advised to use their own criteria and/or testing to confirm suitability.

**NOTE:** For each frequency band, Siretta provides a traffic light indication to show the suitability of the antenna for use at that frequency band. Determination of exactly what makes an antenna good or bad at any frequency is subjective. 

The view presented is that of Siretta’s engineering team having taken into account the efficiency and VSWR measurements. The end user is advised to use their own criteria and/or testing to confirm suitability.
