COMPATIBLE WITH 433MHZ ISM BAND DEVICES: Optimized for the 433MHz ISM band, compatible with garage door openers, wireless weather stations, security sensors, smart home hubs, and remote-controlled lighting systems. SMA-Male connector fits any 433MHz device with SMA-Female jack. Also works with home automation, access control, smart metering, telemetry, and IoT LoRa modules. NOT compatible with RP-SMA, BNC, TNC, N-Type, or 315MHz and 868/915MHz devices. PRO-GRADE AMATEUR RADIO PERFORMANCE: Engineered for high-precision projects including TinyGS (LoRa-based cubesat ground stations) and LoRa APRS iGate. Provides exceptional signal stability on 433.775 MHz, making it a must-have for Ham Radio enthusiasts and satellite trackers. The omnidirectional pattern ensures reliable reception across the entire 433MHz band, ideal for SDR receivers, radio transmitters, and IoT gateway deployments. RUGGED ALL-WEATHER CONSTRUCTION: Built for the outdoors, featuring an anodized aluminum mounting pole and L-bracket. The vertical element and four ground radials are crafted from chromium-plated brass, offering superior corrosion resistance and durability against harsh wind and rain. Ideal for permanent outdoor installation on garage exteriors, gate posts, building walls, and rooftops requiring reliable weather-resistant antenna performance. SUPERIOR SIGNAL STABILITY: This 1/4 wavelength omnidirectional antenna features a threaded assembly system. All components screw together securely, ensuring maximum mechanical stability, zero-loss electrical connectivity, and easy tool-free installation. The threaded design maintains reliable electrical contact even in high-vibration environments, providing consistent signal quality for garage door openers, gate controllers, and IoT sensor networks. LOW-LOSS PLUG-AND-PLAY KIT: Comes pre-equipped with a 9.8-foot (3m) RG58 50-ohm coaxial cable terminated with a high-quality SMA-Male connector. Offers direct, seamless connection to most SDR receivers (like RTL-SDR), radio transmitters, and IoT gateways. The 3-meter cable provides flexible installation options, allowing optimal antenna placement for maximum signal coverage across garage doors, gates, alarms, and smart home systems. COAXIAL CABLE SHIELD GROUNDING: The shield of the RG58 coaxial cable must be properly grounded to the device chassis ground at the radio or receiver end. This reduces interference and ensures clear signal transmission. Proper grounding creates a return path for noise currents, preventing them from coupling into the signal. The direct ground lightning protection design also dissipates static charges and surges, protecting 433MHz equipment from electrical damage during storms. TECHNICAL SPECIFICATIONS: Frequency: 433MHz.
