Siretta DELTA Series Direct Connect Antennas - Siretta DELTA7A/x/SMAM/RP/S/11, Siretta's Delta 7A is a dual band WiFi antenna, tuned to 2.4GHz and 5.8GHz with a peak gain of 2.1dBi. 110mm long, its compact design and hinged joint makes the Delta 7A a very versatile antenna that suits most WiFi applications. Its hinged joint provides a flexible means of setting the antenna into its optimum position for WiFi transmission. The Delta 7A is commonly used with WiFi, Bluetooth, Zigbee and ISM based applications to improve the signal strength and boost the performance of your short-range terminal.Using a badly designed antenna can result in poor performance and noticeably slower data transfer rates. By simply swapping existing antennas to the Delta 7A can help to reach higher data transfer rates. With dual band compatibility (2.4 / 5.8GHz) the Delta 7A can be used with most modern WiFi modems such as NetGear and TP-link that operate on the traditional 2.4GHz and now the less congested 5.8GHz
