The UK Radio Astronomy Association will be at the International Astronomy Show on the 1st November 2025 in Coventry. If you are attending please visit our stand and have a chat. To encourage a wider interest in geophysics we will be selling our magnetometer at a significant discount. The rest of our products will be on sale with a small discount.
The IAS is at The Sports Connexion, Leamington Road, Ryton On Dunsmore, Coventry, CV8 3FL on Saturday 1st November 2025, between 09:00 and 17:00. There is ample free parking on site.
Looking forward to meeting you

The UK Radio Astronomy Association was established in 2008 as a registered charity (registration no 1123866).
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.

UKRAA is pleased to announce that a new assembled version of the E-field Active Antenna Amplifier Kit is available for purchase. Three versions of the kit are available to purchase from our online shop:
- An SMD component kit comprising the PCB and all SMD components can be purchased here from our online store.
- An assembled module with the SMD components mounted and tested can be purchased here from our online store.
- A fully assembled module with the RF and power connectors mounted can be purchased here from our online store.
This kit won the Construction category at the RSGB Construction Competition 2016 and its usefulness was highlighted by John Rogers and David Lauder at this year's RSGB convention RFI Clinic.
In addition, one of UKRAA’s Trustees has looked at how to produce a simple low cost enclosure for the antenna and a short note on the E-Field probe Antenna Housing is available to download.
We have added to our bookshop the third edition of Dr Gerrit Verschuur's excellent book on the history and future of radio astronomy: 'The Invisible Universe - The Story of Radio Astronomy'.
