Can this antenna be used on non-metallic surfaces like plastic or fiberglass enclosures?\u003c\/h3\u003e\n\u003cp\u003eYes, it will function physically, but for optimal RF radiation efficiency, it is recommended to place the magnetic base on a metallic surface. Metallic panels act as a RF ground plane, which helps maintain the tuned resonant frequency, optimal impedance matching, and full 6dBi directional pattern.\u003c\/p\u003e\n\u003ch3\u003e2. Is the SMA-J connector compatible with RP-SMA interfaces found on some Wi-Fi or LoRa devices?\u003c\/h3\u003e\n\u003cp\u003eNo, the SMA-J is a standard SMA Male connector featuring internal threads and a center pin. RP-SMA (Reverse Polarity SMA) connectors have reversed center pins\/receptacles. Please ensure your device chassis has a standard SMA-K (Female, external thread with center hole) receptacle. If your device uses RP-SMA or IPEX connectors, a proper coaxial adapter will be required.\u003c\/p\u003e\n\u003ch3\u003e3. How does this top-loaded sucker antenna handle high-vibration industrial environments?\u003c\/h3\u003e\n\u003cp\u003eThe antenna utilizes an industrial-grade permanent magnetic base that provides strong magnetic holding force against iron or steel surfaces. The top-loaded coil structure maintains high radiation performance while keeping the mechanical center of gravity balanced, preventing mechanical displacement under typical industrial equipment or vehicle vibration.\u003c\/p\u003e\n\u003ch3\u003e4. What is the difference between operating this antenna at 868MHz versus 915MHz?\u003c\/h3\u003e\n\u003cp\u003eThe TX900-XPL33-100 is broadband-tuned across both the 868MHz (standard European ISM \/ LoRaWAN band) and 915MHz (North\/South American ISM band) spectrums. The antenna maintains a low Voltage Standing Wave Ratio (VSWR ≤ 1.5) across both center frequencies, allowing global equipment manufacturers to standardize on a single antenna hardware for international product shipments.\u003c\/p\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"Default Title","offer_id":48611193028813,"sku":"TX900-XPL33-100","price":2.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/TX900-XPL33-100.jpg?v=1785999187","url":"https:\/\/ebyteiot.com\/fr\/products\/ebyte-tx900-xpl33-100-868mhz-915mhz-sucker-antenna-6dbi-sma-j","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
