Marine TVRO antenna / ST-88
The Sea Tel ST88 is our 2.1m TV-at-Sea? system, the best fit for large vessels that operate in Coastal regions.
The ST88 is based on our 8897B system with reliable and proven MK2 electronics that are also used in our XX09, XX10 and XX11 antenna systems. The MK2 electronics have a host of improvements for improved productivity. These include: LED indicators for troubleshooting, USB port for BlueTooth adaptor and digital control interface between the motor driver and PCU for improved communications. The level cage used in the predecessor systems has also been replaced by high accuracy accelerometers. This allows for continuous calculation of position, orientation and velocity vector of a moving object without the need for external references.
Product DescriptionFile DownloadProduct Specification
The micro-electromechanical (MEM) sensors used in Sea Tel’s antennas are based on the same technology currently being used in missile and aerospace technology around the world.
Much like its predecessor, the ST88 is available in C-band and Ku-band configurations or “dual-band” configuration that permits the same antenna to be used for both. The ST88 is designed and built to pass the U.S. Navy’s tests for vibration, shock and protection against RFI and EMI emissions.

? Reception: Single C-Band (linear or Circular)/ Single Ku-Band (Linear Only), Dual C-Band Linear, Quad Ku-Band linear, Dual C-Band Linear/Quad Ku-Band linear(Can be configured to receive 2 C-Band and 2 Ku-Band signals simultaneously or 4 Ku-Band signals simultaneously)
? Ku-band: The entire frequency range for Ku-band satellite television is 10.7 to 12.75 GHz. Proper polarization is also an issue as both linear polarizations (horizontal & vertical) and circular polarizations (left & right) are used, and one configuration is not compatible with the other.
? C-band: The C-band frequency range is 3.7 to 4.2 GHz worldwide. Sea Tel TV-at-Sea? systems are delivered with C-band LNB noise temperatures of 17 degrees K or better. The IF frequency in all cases is 950-1450 MHz
? Designed to meet Navy MIL-STD-167-1 vibration standard and MIL-STD-461 EMI & RFI standards (including 200V/M).
