What is a repeater on a microwave route?

  • A.A station that receives, amplifies and retransmits the signal
  • B.A device that reflects the beam without any electronics
  • C.An antenna that radiates in two directions simultaneously
  • D.A filter that removes interference from the received signal

Answer: A

An active repeater receives on one frequency, amplifies or regenerates the signal and retransmits it on another towards the next site, breaking a long route into hops each within line of sight. Passive reflectors achieve a change of direction without electronics, and filters and dual beam antennas are components rather than stations. Chaining short hops to cross a long distance is what makes terrestrial microwave routes possible over any terrain.
