Use this tag for questions specifically about line of sight communications, as opposed to communications using active or passive reflectors (repeaters, meteor scatter, ionospheric propagation, etc.). Line of sight is the normal propagation mode on VHF and up, where on HF ionospheric propagation is normally used.
