Rantelon designs, develops and manufactures innovative electronic systems with in-house capabilities in electronics, software, mechanics and radio technology. During its 25 years of operations, Rantelon has become a company with a workforce of almost 50 employees whose level of quality of work has won company the trust of many established clients from the civil, security and industrial sectors.

Rantelon was founded in 1995 by then Tallinn University of Technology Department of Radio and Communication Engineering professor Andres Taklaja and engineer Priit Kinks. Working with the American radio electronics company MITEQ and its foreign Estonian president Aksel Kiiss played an important role in the founding of the company.

Even now, 25 years later, both founders remain hard at work – now as the CEOs and owners of one of the most successful high-tech companies in Estonia. Most of all, even today an academic outlook valuing total professional engagement forms an important strand of the company’s DNA.

Its team, comprising talented practising engineers with their vast knowledge of their field, has played a key role in the company’s growth.

Adding much-needed practical possibilities and skills to this considerable human factor, the company has been able to create an array of innovative new devices and systems, bringing people together and making the world a safer place. Its capacity to independently manufacture from idea to finished product and to reproduce it on site is unique and means that Rantelon is able to respond more quickly and flexibly compared to other enterprises.

As such, a compact value offer awaits you as our client – product development from idea to fruition along with all of the necessary innovations and further development for its life cycle, not to mention logistics.

In 2019 Rantelon opened its spacious new research centre and factory. Modern production options have allowed the company to increase its capacity substantially and to continue its rapid growth. In doing so, Rantelon has also preserved the bridge between product development and production, carrying your ideas to higher levels. Developing high-tech solutions to face the global challenges that lie ahead has been given a new lease on life.
