GW.48.A151 2.4 / 5.8GHz 双频 3-3.5dBi 橡皮鸭偶极子天线，RP-SMA（M）
The GW.48 dual-band 2.4/5.8GHz RP-SMA(M) mount dipole antenna is designed for superior performance and reliability. With an omnidirectional radiation pattern and excellent efficiency and gain on both 2.4 GHz and 5.8 GHz bands.
At just 89.5mm in height, the GW.48 is a great smaller form factor solution for Bluetooth and Wireless LAN networks. The IP67 rated enclosure makes it suitable for both indoor and outdoor applications. The flexible IK05 rated TPEE enclosure is impact resistant and durable and has the added benefit of UV resistance, allowing it to meet the needs of demanding outdoor applications.
The GW.48 has a 3.5 dBi Peak Gain at 2.4GHz and 3 dBi Peak Gain @ 5.8GHz making it a cost-effective, high-performing choice for any outdoor application operating at 2.4 or 5.8 GHz. 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, giving you better performance.
