In large-scale satellite ground station projects, antenna selection is often only the starting point of the whole engineering effort; what truly determines project success is the complete service chain running from design through construction to long-term operation and maintenance. Taking our 7.3m earth station antenna as an example, this article shows how a mature engineering, installation, adjustments, maintenance and training service system supports users in completing station construction smoothly and achieving stable long-term operation.
The engineering design stage forms the foundation of the whole process. Centered on the foundation drawing that accompanies the 7.3m earth station antenna, the design team works out a complete plan based on the local climate conditions, frequency band requirements and site topography, covering the concrete foundation dimensions and reinforcement requirements so that the construction party can build directly from the drawing without repeated back-and-forth communication, which significantly shortens the preparation time. Once the foundation work is finished, on-site installation follows, with the main reflector, sub-reflector, feed system, and the elevation-azimuth drive assembly installed in sequence. Because the reflector can be interchanged freely and the antenna offers high precision re-installation performance, installation personnel do not need to repeatedly fine-tune every reflector panel the way traditional antennas require, which considerably lowers the difficulty of on-site adjustment and shortens the overall construction period. Behind this lies years of engineering experience in antenna structural design and installation that the technical team has accumulated, enabling practical construction solutions tailored to different site conditions.
System commissioning is the stage that most tests experience, involving precision calibration of the azimuth and elevation axes, adjustment of the feed polarization angle, and joint debugging of the transmit-and-receive links. To help users install, adjust, use and maintain the system independently after delivery, the particular booklets of installation, application and maintenance are provided together with the equipment, along with a technology training program. This combination of documentation and training effectively turns years of field experience accumulated by the engineering team into skills the users themselves can master, reducing dependence on on-site support from the manufacturer afterward - which is also why the team consistently provides complete technical documentation and a training program together with the equipment.
In terms of the product design itself, the SSA-730 is of Cassegrain type, and its metal components are treated with hot-dip zinc technology, which effectively prevents zinc from volatilizing from the coating over time - a factor that matters greatly for an earth station antenna exposed outdoors year-round to wind, sun and rain. At the same time, the overall structure is specially optimized for wind resistance, allowing it to remain structurally stable under harsh weather conditions, while optional deicing and snowmelt equipment, lightning protection and grounding devices, and light control aviation warning devices further extend the antenna's adaptability to complex climate environments. This antenna meets the requirements of CCIR580 and INTERSAT, with a minimum life expectancy of 15 years, providing a long-term guarantee for users' investment.
Regarding electrical performance, the SSA-730 supports both C band and Ku band operation. In C band, the receive frequency covers 3.4 to 4.2GHz and the transmit frequency covers 5.85 to 6.725GHz, with mid-band gain reaching 48dBi on receive and 51.6dBi on transmit; in Ku band, the receive frequency covers 10.95 to 12.75GHz and the transmit frequency covers 13.75 to 14.5GHz, with mid-band gain reaching 57.5dBi and 58.9dBi respectively. The antenna supports both linear and circular polarization feed configurations, with XPD (on axis) reaching 35dB, VSWR controlled within 1.25, and isolation from Tx to Rx reaching 85dB. Users can also choose between manual or motorized mode and two-axis or three-axis configurations, with the feed ports flexibly available in 2 or 4 ports, fully accommodating customized configuration needs across C band and Ku band applications.
In terms of applications, this type of 7.3m earth station antenna is widely used in gateway station construction for telecommunication departments, and is also commonly found in fields such as the Seismological Bureau, roads and traffic authority, remote sensing, and the State Weather Bureau, serving as important infrastructure for maintaining stable satellite link transmission. The engineering case experience the team has built up across these fields also allows the solution design to better fit the actual operating needs of each site.
For users currently planning earth station construction or antenna equipment upgrades, choosing an antenna product backed by a complete engineering service capability means receiving systematic technical support all the way from foundation construction through long-term maintenance, without having to face complex on-site commissioning and maintenance challenges alone after delivery.
