They are physically similar but electrically incompatible — always match the antenna connector type to your device's port before ordering this 433MHz stub antenna.\u003c\/p\u003e\n\u003ch4\u003eQ: What devices is this 433MHz glue stick antenna compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This 10cm 433MHz antenna is compatible with any device operating in the 423–440MHz frequency band with a 50-ohm RF port, including LoRa\/LoRaWAN modules, 433MHz RC transmitters and receivers, wireless sensor nodes, IoT gateways, smart home hubs, and amateur radio QRP rigs.\u003c\/p\u003e\n\u003ch4\u003eQ: Will the 2 dBi gain improve my wireless range?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. A 2 dBi gain antenna provides a modest but meaningful improvement over a bare PCB trace or wire stub antenna. Combined with the antenna's optimized 433MHz resonance, you can expect better signal reliability and slightly extended range in typical open-air and indoor environments.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
