## 1. Introduction 

The Taoglas GW.51 is a white full band Wi-Fi terminal mount dipole antenna. At just 198mm in height and 13mm in diameter, the robust TPEE enclosure can be mounted straight or at right angle to the device with its hinged RPSMA(M) connector. It is ideal for applications such as Bluetooth, BLE, ZigBee, Wi-Fi 6 & 7 and Wireless LAN. The GW.51, designed for superior performance and reliability, has an omnidirectional radiation pattern and extremely high efficiency and gain on all Wi-Fi bands. 

Typical applications include: 

- Smart Home     - Gateways/Routers     - Connected Agriculture 

The GW.51 has up to 5dBi Peak making it a cost-effective, high-performing choice for any indoor or outdoor application. Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on free-space conditions. In practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or 2dBi when installed. 

So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect. This provides you with improved performance. Upon testing of any of our antennas with your device and appropriate layout, integration technique, or cable, we can work with you to make any of our antennas’ perform below the peak gain limits. 

Taoglas can then issue a specification and/or report for the selected antenna in your device that will clearly show it complying with the peak gain limits. You can be assured that you are meeting the regulatory requirements for that module whilst getting the best performance possible, without exceeding the peak gain limits. 

For further information, or support to test and integrate this product please contact your regional Taoglas customer support team.
