The company made radio equipment for the Merchant Navy after World War One, and the Polar R tube at the same time. Domestic radio sets and components were also made with the trade name "Polar".

Founded: 1919
Production: 1919 -

The Radio Communications Company was founded after World War One by Basil Binyon. He graduated from Trinity College in Cambridge in 1903 and did a post graduate course in Electrical Engineering before working with the Cambridge Scientific Instrument Co. In 1909 he worked with Marconi at Poldhu on the transatlantic transmission to Newfoundland. He was employed by the Marconi Wireless Telegraph Co.

in 1911 he was appointed engineer at Cie.Generale Radiotelegraphique in Paris and became General Manager of the Anglo French Wireless Co. In World War One he was commissioned to the Royal Naval Air Service  and was made Officer in Charge of the Wireless Experimental Department in 1916. He was awarded the OBE for his work on ground telephony. 

Following the War, he began the Radio Communications Company and produced equipment and trained wireless operators for the Merchant Navy and British Navy. He was a director of C F Elwell Ltd and also the Mullard Radio Valve Co. It was with his backing that Mullard was established. A Polar R tube is shown on page 393 of Tyne's "Saga of the Vacuum Tube" but these might have been made for the company by Mullard. He was one of the directors of the BBC in 1922

The company merged with the Marconi Company in the late 1920's and he was a member of this company's Board.

This manufacturer was suggested by Konrad Birkner † 12.08.2014.
