The contract value is 588,333 GBP. The procurement stage was an award, with the tender period ending on 2nd February 2024 and the contract period starting on 5th February 2024 and ending on 4th February 2025. The procurement falls under the industry category of "Parts of radio and radar equipment" in the South East region of the United Kingdom. This tender presents an opportunity for businesses specialising in radio and radar equipment to expand their operations. The contract awarded to KTF Services LLC by UK Research & Innovation involves supplying a X-band Cassegrain Feed Tower & Frequency Selective Sub-Reflector. Businesses experienced in providing such technical equipment and carrying out installation and alignment services would be well-suited to compete. As the contract period spans a year, successful bidders can establish a long-term relationship with UK Research & Innovation, potentially leading to further business opportunities. ## Notice The Chilbolton observatory operates a 25m diameter, prime focus, parabolic reflector antenna with an F/d ratio of 0.36. The antenna was commissioned in 1967 and has for many years been used with an S-band radar fed from the prime focus point. The main feed is undergoing an upgrade to implement monopulse tracking. At the same time the observatory would like to add a wide band X-band radar to the antenna for simultaneous operation with the S-band radar. The intention is to use the S-band radar for tracking and ranging of satellites while the wide bandwidth X-band radar is used for imaging. The antenna was commissioned in 1967 and there are no CAD drawings for the structure. Contractors may wish to visit the site to conduct a survey of the structure and check mounting points, access to the backing structure etc that will become important in the design, installation and alignment of the feed tower and the sub-reflector. It is not thought possible to integrate an X-band feed with the S-band monopulse feed at prime focus. The solution proposed is one used in satellite communications ground stations of having the S-band feed at the prime focus of the reflector and the X-band feed in a tower mounted in the centre of the dish forming a cassegrain arrangement with a frequency selective sub reflector. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/fb68869f-17f4-4c13-9355-738fa4df4b0c | | Notice type | Award Notice | | Procurement type | Standard | | Procurement category | Goods | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | SME | | All stages | Award | ## Dates | Field | Value | | --- | --- | | Publication date | 15 Feb 2024 | | Submission deadline | 2 Feb 2024 | | Future notice date | Not specified | | Award date | 2 Feb 2024 | | Contract period | 5 Feb 2024 - 4 Feb 2025 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £588,333 | | Lots value | Not specified | | Awards value | £588,333 | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Not specified | | Awards status | Active | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UK RESEARCH & INNOVATION | | Locality | OXFORD | | Post town | Oxford | | Postcode | OX11 0QX | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ1 Berkshire, Buckinghamshire and Oxfordshire | | ITL 3 | TLJ14 Oxfordshire CC | | Local authority | Vale of White Horse | | Electoral ward | Blewbury & Harwell | | Westminster constituency | Didcot and Wantage | | Delivery location | TLJ South East (England) | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | KTF SERVICES | ## CPV Codes ### Divisions - 32 - Radio, television, communication, telecommunication and related equipment ### Codes - 32352100 - Parts of radio and radar equipment ## Release History - 15 Feb 2024 at 12:00 - Award - Award Notice - https://www.contractsfinder.service.gov.uk/Notice/fb68869f-17f4-4c13-9355-738fa4df4b0c ## Documents - https://www.contractsfinder.service.gov.uk/Notice/fb68869f-17f4-4c13-9355-738fa4df4b0c 15th February 2024 - Awarded contract notice on Contracts Finder - https://www.delta-esourcing.com/delta/respondToList.html?noticeId=842986570 Please follow this link to view the notice. ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
