UKRAA promotes the science of radio astronomy and all branches of radio astronomical research by designing, manufacturing and selling radio astronomy equipment for amateur astronomers.

The UK Radio Astronomy Association was established in 2008 as a registered charity (registration no 1123866) by the British Astronomical Association’s Radio Astronomy Group (RAG). UKRAA’s objectives are to promote the science of radio astronomy and all branches of radio astronomical research.

UKRAA is a not for profit business. Any surplus income funds the development of new products and our outreach activities. To keep our prices low UKRAA relies on the contributions of volunteers. We need more volunteers who can contribute in these areas of expertise:

  • Precision wood working to make up antenna kits and assembled antennas.
  • Machining and mechanical assembly to make up the enclosures.
  • Electronic assembly both through-hole and surface mount components.
  • Software development.
  • Digital and analogue circuit design and PCB layout experience.
  • IT and Website support.
  • Writers for articles and manuals Stock control, book keeping and customer service.

The UKRAA Magnetometer

Introduction to Radio Astronomy

The first article covers the use of the UKRAA Magnetometer and
encourages amateur astronomers to have a go and observe the earths
magnetism. John Cook (Director BAA Radio Astronomy Section) and Andrew
Thomas (UKRAA Trustee) describe the operation of the magnetometer 
sensor and consider the practicalities of making observations. This
article was first published in Radio Astronomy the Journal of the
Society of Amateur Radio Astronomers (SARA) Journal, Nov-Dec 2020, pp.

The second article is an introduction to radio astronomy for a general
readership. It was published in the February edition Radio User Magazine
and aims to interest the reader in radio astronomy and give guidance to
some introductory projects.

The editors of both magazines are keen to receive articles for
publication and can be contacted through their websites

Society of Amateur Radio Astronomers (SARA)

Radio Enthusiast

In these uncertain times we would like to reassure everybody that the UKRAA team is continuing to operate and fulfil any orders we receive.  We are able to maintain an appropriate social distance, many miles apart, each of us in our respective shed or workshop.  As long as the post continues to operate, we shall be able to dispatch orders as they arrive.

We are all well, so far so good. 

We wish you all good luck in the future.  Stay at home, keep safe and stay well.

UKRAA had a stand at Astrofest 2020 at the end of February this year.  This was the second time we have exhibited at this event and it was a great pleasure to meet a lot of new people and spread the word of amateur radio astronomy.  We would like to thank those familiar faces who sought us out for a chat.

We were pleased with the response of visitors and we have decided to attend next years show.  Looking forward to Astrofest 2021!
