 The experience of losing the distribution rights of Codex made Yehuda realize that his business should never rely on one product line, and in 1981 he asked his brother, Zohar, to join him at Bynet to start working on the development of their own products.They started a new company in a corner of the Bynet offices and gave it the name RAD Data Communications, RAD being the acronym of Research And Development.RAD's first successful product was a miniature (by 1980s standards) computer modem.
