There is no evidence that this company was a radio manufacturer, probably they operated a radio shop. The company started as Astra Lichtreclame Onderneming (neon lights) in 1927. In 1932 the owner, Fritz Sucharipa, was declared bankrupt.

A relation between this company and Astra coils is very unlikely.
