One of the first uses of 'T' aerials in the early 20th century was on ships, since they could be strung between masts. This is the antenna of RMS Titanic, which broadcast the distress call during her sinking in 1912. It was a multiwire 'T' with a 50-metre (160 ft) vertical wire and four 120-metre (400 ft) horizontal wires.
