The ACTS Propagation Terminal

The Humacao propagation terminal utilized an ACTS Propagation Terminal (APT), slightly modified to address the 20.7 GHz observation frequency from UFO9.

Each APT unit consists of:

  • A 1.2-m offset fed reflector
  • RF Feed Enclosure (monitoring 20.2 and 27.5 GHz frequencies)
  • IF Enclosure (IF Frequency: 70 MHz)
  • Data Acquisition and Control System (DACS)
