TracStar V730M 7.3米C,Ku,DBS頻段通信衛(wèi)星天線




7.3米C,Ku,DBS頻段天線
TracStar V730M 7.3米天線為發(fā)送/接收提供,接收L到DBS頻段的應(yīng)用。天線采用反射器設(shè)計,包括成型面板,輪廓徑向和機(jī)加工輪轂組件。



射頻性能
它采用卡塞格林饋電和子濾波器設(shè)計,可實現(xiàn)高增益,低噪聲溫度,高天線效率以及噪聲和微波干擾抑制。反射器由鍍鋅的基座支撐,為指向和跟蹤提供所需的剛度。基座設(shè)計用于軌道弧覆蓋,適應(yīng)地面或屋頂安裝。

7.3 Meter C, Ku, DBS-Band Earth Station Antenna

 7.3-meter antenna delivers exceptional performance for transmit/ receive and receive only applications for L through DBS- band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, contoured radials and a machined hub assembly.


RF Performance

It features an innovative Cassegrain feed and subreflector design which results in high gain, low noise temperature, high antenna efficiency and excellent rejection of noise and microwave interference. A large center hub provides spacious accommodation for equipment mounting. The reflector is supported by a galvanized kingpost pedestal that provides the required stiffness for pointing and tracking accuracy. The pedestals are designed for full orbital arc coverage and are readily adaptable to ground or rooftop installations.


Compliance

The electrical performance is compliant with FCC and ITU-RS-580 sidelobe specifications and Intelsat (F3, E3) and Eutelsat (L, S1) requirements. All configurations meet own type-approved quality assurance and performance guarantee.
