Features 【Broadband Compatibility】This antenna is designed to effectively cover a wide range of frequencies, including those used for mobile communications, UWB (Ultra-Wideband) positioning systems, and WiFi networks, providing versatile functionality for various RF applications 【High Accuracy Directionality】Equipped with a directional beam pattern and minimal side lobes, the R101C gradient slot antenna ensures precise sign targeting and exceptional performance in directional wireless sign transmission, reconnaissance, and direction-finding tasks, with a horizontal beam width of nearly ‑3dB 【Compact and High-Gain Design】Despite its small footprint, the antenna offers high gain, making it a powerful and efficient tool for laboratory environments where space might be limited yet quality sign transmission and reception are essential 【Versatile Installation Options】The antenna's multifunctional bracket allows for straightforward desktop mounting or handheld operation, while additional mounting holes enable dual-use as an independent unit or as a feed source when integrated with a parabolic reflector 【User-Friendly Setup】Designed with ease of installation in mind, this gradient slot antenna can be quickly and securely positioned for immediate use, allowing researchers and technicians to pay attention to their work without the hassle of complex assembly processes. Feature: RETURN LOSS 10dB: The input impedance of the R101C antenna is 50 ohms. When the 50 ohm impedance is connected to the sign source, the fluctuation within the frequency range is less than 10dB, and the corresponding standing ratio is about 2.0. Specification: Item Type: Wideband Directive Antenna Material: PCB Mode: R101C Mechanical Parameters: Interface Type: SMA external thread, internal needle Polarization Mode: Linear polarization Input Impedance: 50 Ω Package List: 1 x Antenna  Note: Safety Instructions: 1. When using, be careful to touch live conductors and avoid electric shock 2. Avoid outdoor use in thunderstorm weather, especially in high mountains or deserts, and quickly move to a lower position and lower the antenna 3. When climbing, it must be carried reliably to avoid falling 4. The antenna has edges and corners, please be careful not to scratch it when charging. 5. Antenna connectors and feeders cannot withstand weight. Avoid pulling during use. The feeder can be fixed in the fixed antenna hole with ties. Antenna Maintenance:  In practical use, in order to extend the service life of the antenna, please pay attention to the following items 1. Avoid heavy pressure, collisions, and scratches on the antenna 2. Avoid excessive bending of cables 3. When unfolding the antenna bracket, Please place it on a horizontal plane to prevent it from falling. Package List 1 x Antenna
