What Sure Antennas does
Sure Antennas (now operating as 'Sure Antennas, a Taoglas company' following its June 2026 acquisition by Taoglas, a Graham Partners portfolio company) is a UK-based specialist manufacturer of vehicle-mounted antenna systems for critical communications, founded in 1977 and headquartered in Bromborough, Merseyside, with a European office in Hoofddorp, Netherlands. The company designs and produces multi-function antennas that consolidate 4G/5G LTE, TETRA, GPS/GNSS, WiFi and UHF/VHF functions into single-hole-install units — its flagship Sandcastle antenna supports up to 18 functions and its Mallard sharkfin supports up to 9 — alongside motorbike antennas (8-in-1), covert OEM antenna modification services, and complementary vehicle technology including Cradlepoint and Teltonika routers and the Handsfree R5 ESN-ready fixed vehicle device.
The company's commercial focus is on UK emergency services (police, fire & rescue, NHS ambulance trusts) plus selected European and international emergency forces, with ARP (Ambulance Radio Programme) approval, ESN-readiness and Airwave approval positioning it for the ongoing TETRA-to-ESN transition. Sure Antennas operates a B2B sales-led, quote-based go-to-market with a 2 working hour quote response commitment, distributing through direct sales to fleet and procurement teams, named vehicle converter partnerships (Cartwright, TS Comms, Jack Hodson Ltd, Richell, Toyota), and a European reseller network, supported by a Motorola Solutions Platinum Partner channel relationship.
Revenue is generated primarily through hardware sales of antennas, TETRA radios and accessories, vehicle routers and custom RF cable assemblies, supplemented by bespoke covert OEM antenna modification services. Previously a wholly-owned subsidiary of SFL Mobile Radio Holdings Group, Sure Antennas has 45 employees and holds ISO 9001 and Cyber Essentials certifications, with its operating geographies spanning the United Kingdom, the Netherlands and selected European deployments (including Polish emergency forces).

Sure Antennas competitors and assessment
Company assessmentDirect peers
- Panorama Antennas: UK-based designer and manufacturer of antennas for land mobile radio, vehicle, and critical communications applications. Direct competitor in vehicle-mounted multi-function antennas for emergency services across the UK and Europe, with overlapping Motorola-compatible product positioning.
- Calearo Antenne: Italian automotive antenna specialist producing shark-fin, covert, and multi-function antennas for OEM and aftermarket vehicle applications. Comparable as a European tier-1/2 supplier of integrated vehicle antenna solutions competing for similar fleet and emergency-services business.
- Smarteq Wireless (Hella/HELLA): European vehicle antenna manufacturer (now part of Hella/FORVIA) producing multi-function and shark-fin antennas for commercial vehicles, fleets, and emergency services. Directly comparable on automotive antenna integration and OEM channel approach.
Broad incumbents
- Laird Connectivity (TE Connectivity): Broad RF/antenna, IoT, and connectivity components portfolio under TE Connectivity. Overlaps with Sure Antennas on external vehicle antennas and wireless modules, but operates across many verticals beyond emergency services.
- PCTEL (Amphenol): Global manufacturer of antennas and RF conditioning products for industrial, fleet, and public-safety wireless networks. Now part of Amphenol, giving it broader reach but a less specialized vehicle-focused footprint than Sure Antennas.
- Airgain: US-based designer of antenna systems and embedded wireless technologies for automotive, fleet, enterprise, and IoT applications. Comparable as an antenna specialist serving connected-vehicle use cases, but with broader non-emergency focus.
- HUBER+SUHNER: Swiss manufacturer of RF connectors, cables, and antennas serving rail, automotive, and critical communications markets. Overlaps on RF cabling/accessories and selected antenna products for mobility and emergency-services use cases.
- Kathrein (Ericsson): Germany-headquartered antenna specialist (now part of Ericsson) covering automotive, IoT, and critical communications. Comparable as a vehicle-antenna supplier with adjacent public-safety exposure but a much broader telecom-platform portfolio.
Regional players
- Harada Industry: Japan-based tier-1 automotive antenna supplier serving global OEMs. Operates in the same vehicle-antenna category but primarily serves Japanese/Asian OEMs and not directly competing in the UK/European emergency-services aftermarket.
Others
- Taoglas: San Diego-headquartered provider of antennas, RF components, and IoT solutions, and the acquirer of Sure Antennas in 2026. Useful comparable as the parent platform but does not directly compete with the Sure Antennas UK emergency-services product line post-acquisition.
