1、Wide in Range: The R101C antenna has good transmit and receive performance in the entire frequency range of 730MHz-6.5GHz, and the VSWR is less than 0. When the frequency range is exceeded, the antenna gain and return loss are rapidly reduced. When the standing wave ratio is less than 5, it can be used to 700Mz-7GHz. 2、Extensive Use: In addition to independent use, the antenna can be fixed at the focal position of the parabolic reflector as the feed of the parabolic antenna. Ideal for directional radio signal transmission and reception, signal source reconnaissance and direction finding, and broadband signal testing, etc. 3、Reliable Work: The R101C antenna gain increases slowly with increasing frequency, about 5dBi around 800Mhz, 7dBi at 4GHz, and 9dBi at 8GHz. 50 ohm input impedance, when connected to a 50 ohm impedance signal source, it will fluctuate below 10dB in the frequency range. 4、The Directivity: Good directivity in the whole section, and the sidelobe is small. The antenna pattern is wider in the horizontal direction, and the width of ‑3dB is about 60°. The pattern in the elevating direction is narrower, and the width of ‑3dB is about 40°. 5、Easy to Install: Comes with a light weight and a compact size as well, the UWB antenna enables easy installation that can be quickly completed in minutes. 1 x Wideband Directive Antenna Item Type: Wideband Directive AntennaModel: XR-105Material: PCBFrequency: 730MHz- 6.5GHzGain: 7-9dBiPower: 5WConnector: SMA female head. Temperature Range: -45℃ ~ 80℃Humidity Range: 0% ~ 95%, allows for 100% in short term and no water. Waterproof Performance: Need to dry after drenching, replace the connector cable after soaking.
