Product Details
Product Features
Standard mobile communication vehicles often face operational bottlenecks, such as high-clearance antennas striking overhead obstacles and frequent link dropping on rugged roads. The SDL-800 series addresses these field failures by combining high-gain array antennas with aggressive chassis height reduction. By utilizing advanced tracking algorithms to stabilize RF output—achieving an EIRP up to 58 dBW—the terminal maintains massive data throughput and link reliability under low power consumption. Encased in an IP65 weather-proof housing, it ensures that field teams in disaster zones or remote areas maintain an uninterrupted, bidirectional link to headquarters without signal blind spots.

FAQ
- What are the primary differences between the SDL-800 and SDL-800A satellite terminals?
- The main distinctions lie in their operating frequency bands, RF performance specifications, and power usage. The SDL-800 operates on the Ku-band with a receive range of 10.7–12.75 GHz, a power consumption of ≤380W, and a G/T ratio over 11 dB/K. Conversely, the SDL-800A utilizes the higher-frequency Ka-band (Rx: 17.7–21.2 GHz), draws less power (≤280W), and leverages Ka-band high-gain characteristics to achieve a higher EIRP of over 58 dBW. Users can select the model based on their available satellite resources and target bandwidth requirements.
- Does mounting this COTM terminal on a vehicle require extensive modifications?
- No structural modifications are needed. The SDL-800 series is specifically optimized for low-profile applications, measuring only 13 cm in height with a net weight of 42 kg for the SDL-800 and 46 kg for the SDL-800A. This lightweight distribution allows the unit to be mounted directly onto standard roof racks or basic crossbars without cutting into the roof. It fits a wide array of SUVs, off-road vehicles, vans, and emergency command vehicles without triggering safety compliance issues or vehicle inspection failures.
- How does the terminal maintain a stable connection during high-speed driving or off-road shaking?
- This mobile satellite terminal utilizes a built-in high-precision inertial navigation tracking system paired with nanosecond-level electronic scanning controls. When the vehicle executes sudden turns, accelerates, or traverses deeply rutted roads, the antenna algorithms adjust elevation and azimuth alignment within microseconds or nanoseconds. This ensures that the antenna main lobe continuously points directly at the geostationary satellite, preventing packet loss and guaranteeing uninterrupted voice, video, and data transmission while in motion.
