The Radio

Bio
The Castaways Radio was a Packard Bell AR-851 AM Radio which remained their only source of contact with civilization, providing news on current events, weather reports and entertainment programs for their amusement. It's ownership is a bit in question; in most episodes, it seems to be the property of the Skipper loaned out to the respective castaways, but in Will the Real Mr. Howell Please Stand Up?, Mr. Howell claims it belongs to him. Once swallowed by a fish after Gilligan tosses it into the surf, the batteries in the radio wear out by X Marks the Spot but the Skipper produces rechargeable batteries that allow it to be recharged into perpetuity for as long as the Professor can keep fixing it, usually from Gilligan knocking off the table. However, it is revealed that it finally does give out sometime before the castaways are rescued.

 * Alice McNeil is traveling around the world in the "Vagabond Lady"

Trivia

 * Some promotional shots show the Castaways posing with another radio, a Magnavox Celestial Model FM-97.
 * The Castaways radio was a single AM band radio, which makes it difficult for them to receive any FM station signals.
 * The handle and antenna on the radio are not actually part of the radio; they were added by the prop department.
 * In Rescue from Gilligan's Island, the Professor reveals the radio stopped working ten years before, which would be two years after the series ended.
