  • Notes

  • The use of wireless telegraph relays was essential for the development of long-distance wireless communication. In the early days of wireless telegraphy, relays were used to extend the range of wireless telegraph systems to hundreds of miles. 

    Here is an example of how a wireless telegraph relay is used in maritime communication:

    • A ship at sea sends a wireless telegraph signal to a shore station.
    • The shore station receives the signal and amplifies and retransmits it using a wireless telegraph relay.
    • The relay retransmits the signal to another shore station, which receives and decodes the signal.
    • The shore station then relays the message to the intended recipient.
