Uav Antenna

Description Radio Astronomy Antenna The 65-meter radio telescope is an astronomical observation device developed by 54th institute and my company serve for the Shanghai Observatory of the Chinese Academy of Sciences. It is the largest antenna with the highest aperture and accuracy in Asia. It is mainly used in deep space exploration and VLBI orbit determination. Project Overview The 500m aperture spherical radio telescope uses the dimpled surface in the Karst area of Guizhou province as a telescope site to build the world's largest single-caliber radio telescope, which has a big receiving area as large as 30 standard football fields. . The FAST project is about 10 times more sensitive than the 100-meter telescope in Bonn, Germany, which was known as the "biggest ground machine in the world". Compared with the American Arecibo 300-meter telescope which was named "The First of the 10th Mankind Project of the 20th Century," the overall performance is about 10 times improved; FAST�??S mission is to explore the neutral hydrogen in the universe, observe pulsars, leading the international low frequency very long baseline interferometry network, detect interstellar molecules, and search for possible interplanetary communication signals. 65 meter radio telescope The 65-meter telescope uses a modified Cassegrain antenna with a 65 meters aperture , a 70 meters height and a approximately 2,700 tons weight. It can work in the eight frequency bands L, S, C, X, Ku, K, Ka and Q. The bottom working frequency is 1.25 GHz and the maximum operating frequency is 46 GHz. S/X and X/Ka are dual frequency simultaneous observations, and the antenna pointing accuracy is better than 3 arc seconds. With actuator, the working accuracy of the main reflector is less 0.3mm ,0.6mm without. The working accuracy of the subreflector is less than 0.1mm and its adjustment adopts Stewart parallel mechanism, which can accurately correct the error of its position. The 65-meter antenna should maintain high surface accuracy under different angles of pitch. In the design stage, the 65-meter antenna structure performs mechanical simulation analysis using finite element technology under various working postures, only the technical specifications such as stress, strain, resonance frequency, etc meet the requirements the optimal topology and cross-section parameters are obtained. For the first time, the 65-meter antenna has adopted the all-orbit welding technology in China. The track is made of 42CrMo material. The maximum height difference after welding is less than 0.5mm and the surface hardness is HRC48~HRC52.

Description Fixed Antenna The 1.8m aperture antennas panels are base coated with yellow strontium and face coated with polyurethane which is good performance for chemical, biology and nuclear protection. The steel structure is treated by sand blasting and zinc spraying, and then base coated with yellow strontium and face coated with polyurethane. Thanks to the application of our advanced laser cutting technology and the good technical cooperation with the 54th Research Institute, my company has formed a full products range of antenna. From the minimum 0.8M diameter home TV antenna to the astronomical detection antenna with 100 meters above diameter, from normal plate shaped satellite antenna to detecting radar antenna ,our products can match the most buyers demands .Our products are of top rank quality and the price is absolutely competitive. Compared with European or American competitor, my product??s performance is similar, maybe more advanced in some respects, and the price will give you a surprise. So, do not hesitate to contact our sales department directly, you will get more surprises. v Fixed 1.8 diameter antenna by single column-Equipments list Equipments list Description Qty 1.8 meter diameter antenna reflector and its supporting devices 1 CTI.A180C-E0651 single column base 1 CTI.A180Ku-E0651 feed source network 1 Foundation templates and embedded parts. 1 Options LNA/LNB 1 Transmitting feeders (only including azimuth waveguide, pitch waveguide, polarization soft waveguides and rectangular waveguides link to column) 1 waveguide inflator 1 obstruction light 2 lighting rods and ground wires 1 � Power and signal lightning protection devices. 1 de-icing and snow thawing device of main reflector 1 movable sub-grade foundation. 1
