Whether you are building a long-range UAV or just trying to send telemetry to a ground station three counties away, this RFDesign 1\/4 wave monopole is the 'no-frills, all-thrills' choice for makers who prioritize weight over flashy plastic casings. It’s sleek, it’s tiny, and it’s surprisingly good at its job—much like a well-trained ferret.\u003c\/p\u003e\n\u003ch3\u003eWhy You Want It\u003c\/h3\u003e\n\u003cp\u003eThis antenna is the minimalist's dream. At a mere 10 grams, it’s roughly the weight of three grapes or the amount of patience you have left after your third 'failsafe' of the afternoon. It is purpose-built for airborne FPV applications where every milligram is a mortal enemy. Just a heads-up for the skimmers: it’s a monopole. It needs a ground plane to perform. If you mount this to a piece of wood and wonder why your signal is trash, that’s on you. We're breaking the fourth wall here to save your hardware: mount it to something conductive or provide a counterpoise.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency range: 902-928MHz\u003c\/li\u003e\n\u003cli\u003eGain: 2.1dBi\u003c\/li\u003e\n\u003cli\u003eVSWR: \u0026lt; 1.5\u003c\/li\u003e\n\u003cli\u003eImpedance: 50R\u003c\/li\u003e\n\u003cli\u003ePolarization: Vertical\u003c\/li\u003e\n\u003cli\u003eWeight: 10g\u003c\/li\u003e\n\u003cli\u003eSize: 51mm long, 8mm diameter\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x RFDesign 900MHz 1\/4 Wave Monopole Antenna (RPSMA)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eWorks flawlessly with any 900MHz\/868MHz radio systems utilizing an RPSMA connector.
