The specially designed click in plastic head greatly reduces the assembly time and cost compared with most terminal antennas with a connector. The product comes with 250mm low loss RG-178 cable and IPEX MHFI �® (U.FL) connector. Having the cable and IPEX connector coming out directly from the housing eliminates the need for a separate costly cable assembly and bulky mating connector on the device.\u003c\/p\u003e \u003cp\u003eMany 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 put inside a device. 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.\u003c\/p\u003e \u003cp\u003eFor example, a module manufacturer may state that the antenna must have less than 2dBi peak gain, but you donâ��t need to select an embedded antenna that has a peak gain of less than 2dBi in free-space. This will give you a less optimized solution. It is better to go for a slightly higher free-space peak gain of 3dBi or more if available. Once that antenna gets integrated into your device, performance will degrade below this 2dBi peak gain due to the effects of GND plane, surrounding components, and device housing.\u003c\/p\u003e \u003cp\u003eThe GW.17 has excellent stable radiation properties in all mounting conditions, mounted with and without a ground-plane, in bent 90 degrees or straight position.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eFrequency: 2.4~2.5GHz\u003c\/li\u003e \u003cli\u003ePeak Gain (straight): 2.7dBi\u003c\/li\u003e \u003cli\u003ePeak Gain (bend): 1.6dBi\u003c\/li\u003e \u003cli\u003eAverage Gain (straight): -1.3dBi\u003c\/li\u003e \u003cli\u003eAverage Gain (bend): -1.3dBi\u003c\/li\u003e \u003cli\u003eEfficiency (straight): 74%\u003c\/li\u003e \u003cli\u003eEfficiency (bend): 74%\u003c\/li\u003e \u003cli\u003ePolarization: Linear\u003c\/li\u003e \u003cli\u003eImpedance: 50 Ohms\u003c\/li\u003e \u003cli\u003eRadiation Pattern: Omni\u003c\/li\u003e \u003cli\u003eInput Power: 2W max\u003c\/li\u003e \u003cli\u003eAntenna Length: 112.6mm\u003c\/li\u003e \u003cli\u003eAntenna Diameter: 9.3mm\u003c\/li\u003e \u003cli\u003eAntenna Body Material: TPU\u003c\/li\u003e \u003cli\u003eTemperature Range: -40�°C to 85�°C\u003c\/li\u003e \u003cli\u003eHumidity: Non-condensing 65�°C 95% RH\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/3\/9\/3\/9\/9\/DS-17733-2.4GHz_Terminal_Antenna__I-PEX_MHF___I__U.FL___250mm_RG-178.pdf\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054703292501,"sku":"17733:WRL-17733:spark","price":1915.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/17733-2.4GHz_Terminal_Antenna__I-PEX_MHF___I__U.FL___250mm_RG-178-01.jpg?v=1651344328","url":"https:\/\/www.tanotis.com\/products\/sparkfun-2-4ghz-terminal-antenna-i-pex-mhf-atilde-acirc-reg-i-u-fl-250mm-rg-178","provider":"Tanotis","version":"1.0","type":"link"}
