I believe what Channel 45 does is receive and relay Channel 28 from Maui, which receives and relays Channel 5 from Honolulu. So 45 is the last hop. If there's something wrong with the path between Honolulu and Maui or Maui and The Saddle, it would knock out the signal source of 45.
5 (HNL) -> 27 (OGG) -> 45 (ITO)
