TracStar V730M 7.3米C，Ku，DBS频段通信卫星天线

7.3米C，Ku，DBS频段天线
TracStar V730M 7.3米天线为发送/接收提供，接收L到DBS频段的应用。天线采用反射器设计，包括成型面板，轮廓径向和机加工轮毂组件。

射频性能
它采用卡塞格林馈电和子滤波器设计，可实现高增益，低噪声温度，高天线效率以及噪声和微波干扰抑制。反射器由镀锌的基座支撑，为指向和跟踪提供所需的刚度。基座设计用于轨道弧覆盖，适应地面或屋顶安装。

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.
