Product Details
1. This product is a small multi frequency external antenna that supports the Beidou 1st and Beidou 2nd generation satellite systems. It can meet the current reception and transmission requirements of Beidou 1st generation transceiver communication and Beidou 2nd generation B3 frequency band for Beidou satellite mobile terminals and onboard mobile terminals.
2. The antenna adopts a multi feed point design scheme to achieve the overlap of the phase center and geometric center, minimizing the impact of receiver measurement errors introduced by the antenna; The antenna unit has high gain and wide directional beam width, ensuring the reception effect of low elevation signals, and can still receive satellites normally in high occlusion environments; It has superior performance such as signal stability, small size, light weight, waterproof, dustproof, sturdy and seismic resistance.
3. The mechanical performance of this product is designed in accordance with the requirements of the national standard, and reliability testing is carried out in accordance with GJB150-2009 "Environmental Testing Methods for Military Equipment Laboratories". It meets the strict working conditions requirements of the national standard in the field, providing guarantee for long-term preservation and field work. This product can be widely used in the navigation scheduling, tracking and monitoring, measurement and control, as well as military security and other work fields of Beidou mobile terminals and onboard ship terminals.
4. This product adopts high-performance ultra soft single cable feeding, with a smaller bending radius, easier bending, and better flexibility, which can meet the requirements of narrow space operation and bending; Stable and reliable performance, large power capacity, low insertion loss, can meet the high current working needs of transmitting signals. The antenna power amplifier has a power detection function, which can effectively reduce power consumption and extend the standby time of mobile terminals when not transmitting signals.
