ETL Systems Ltd: Pioneering RF Technology for Over 35 Years

A Legacy of Excellence

Since its foundation, ETL Systems Ltd has been at the forefront of RF design and manufacturing. The company designs and builds essential components of critical satellite ground-station infrastructure—what it calls “everything between the antenna and the modem.” This means its products handle the vital role of distributing, amplifying, splitting, switching, and conditioning radio-frequency signals in both the uplink and downlink chains that connect Earth to space.

Award-Winning Innovation

Over the years, ETL Systems Limited has achieved recognition at the highest levels of British industry. The company has proudly received three Queen’s Awards for Enterprise in International Trade, a testament to its exceptional export performance and international success. Today, the company exports over 70% of its products worldwide, serving clients across the Americas, Europe, the Middle East, and Asia.

Among its distinguished client base are the top 20 satellite operators and teleports globally, as well as approximately 75% of NATO governments, who rely on ETL Systems’ equipment to maintain secure and reliable communications.

Headquarters and Global Reach

ETL Systems Hereford: The Heart of British Engineering

The main manufacturing and design facility of ETL Systems Ltd Hereford remains at its original base in rural Herefordshire. The Hereford headquarters houses the company’s research and development (R&D) centre, testing laboratories, and manufacturing operations. This site embodies the company’s commitment to British engineering excellence and to maintaining complete control over quality, precision, and innovation.

Expanding Global Presence

While its roots are firmly planted in the UK, ETL Systems has established a strong international presence. The company operates additional facilities and offices in Watford and Braintree (UK), Washington D.C. (United States), and Dubai (United Arab Emirates). This global footprint ensures close relationships with customers and responsive support across time zones and regions.

Specialties and Product Portfolio

Comprehensive RF Distribution Solutions

The key to ETL Systems’ success lies in its comprehensive range of RF distribution equipment. The company provides complete solutions for the uplink and downlink signal paths in satellite ground stations and broadcast facilities. Its product range includes:

• L-band Matrix Routers – High-performance routing systems that allow flexible signal management and redundancy.

• Amplifiers – Low-noise and high-power RF amplifiers ensuring signal integrity across long distances.

• Splitters and Combiners – Essential components for distributing and merging multiple RF signals efficiently.

• Switches and Redundancy Units – Designed to provide continuous operation and minimise downtime.

• LNB Power Supply Units (PSUs) – Power solutions for low-noise block converters and other satellite components.

• RF Systems and Rack Solutions – Fully integrated systems tailored to client requirements, often custom-built.

Acquisitions and Strategic Growth

Innovation and expansion have always been part of ETL Systems’ DNA. The company’s growth strategy includes acquiring complementary businesses to broaden its capabilities:

• In 2019, ETL Systems Ltd acquired Atlantic Microwave Ltd, a specialist in RF instrumentation and measurement equipment. This addition allowed ETL to offer solutions for testing and calibration of RF chains, strengthening its presence in the research and development sector.

• In 2024, ETL further expanded through the acquisition of SpacePath Communications and IRT Technologies, adding a full range of RF high-power amplifiers (HPAs) to its portfolio. These strategic acquisitions have positioned ETL as a one-stop provider for complete RF chain solutions.

Innovation, Quality, and Customer Trust

A Culture of Engineering Excellence

ETL Systems’ reputation has been built upon innovation, quality, and dependability. The company’s engineers continually design cutting-edge systems that meet evolving industry demands such as higher frequencies, wider bandwidths, and integration with digital technologies. Every product is designed and manufactured in the UK to stringent quality standards, ensuring exceptional reliability and performance in even the harshest environments—whether aboard a ship, inside a teleport, or on a defence base.

Trusted by the World’s Most Critical Networks

Few companies can claim such an elite client list. ETL’s products are trusted by organisations where communication failures are not an option. From national defence and government installations to major broadcasters and oil-and-gas communications systems, ETL Systems ensures that vital information flows securely and continuously.

ETL Systems Limited and Its Industry Impact

Driving Global Satellite Connectivity

The modern world depends on uninterrupted connectivity—whether for broadcasting, maritime communication, or defence coordination. ETL Systems plays a vital role in this global network by supplying the hardware backbone that enables satellite operators to manage signal distribution efficiently and reliably.

As new technologies emerge, such as High-Throughput Satellites (HTS), Low Earth Orbit (LEO) constellations, and digital IF distribution, ETL continues to adapt its designs to meet the demands of next-generation communications infrastructure.

Commitment to British Manufacturing

Despite its global success, ETL Systems Ltd Hereford remains proud of its British heritage. Manufacturing within the UK allows the company to maintain total control over design, testing, and quality assurance. This approach also supports local employment, apprenticeships, and engineering talent development, reinforcing Herefordshire’s reputation as a hub of advanced technology.

Future Outlook: Innovation Beyond Boundaries

Expanding Capabilities in RF and Microwave Technologies

With its recent acquisitions and continuous R&D investment, ETL Systems Limited is poised for further growth. The expansion into high-power amplifiers and advanced test equipment signals a broader strategic move toward becoming a complete RF solutions provider. This diversification allows the company to serve not only traditional satellite communication customers but also emerging markets in aerospace, defence, 5G backhaul, and remote sensing.

Sustainability and Responsible Growth

As global industries move toward sustainability, ETL Systems is committed to responsible manufacturing and supply-chain management. Energy-efficient designs, robust long-life products, and minimised electronic waste are part of its ethos. By building durable systems, the company helps reduce maintenance frequency and environmental impact.

Why ETL Systems Stands Out

The success of ETL Systems Ltd can be attributed to a clear and consistent vision: to be the world’s most reliable provider of RF distribution technology. Its strengths lie in:

• Technical mastery gained from 35+ years of experience.

• Comprehensive in-house manufacturing in the UK.

• Global client trust, including defence and government sectors.

• Commitment to innovation through R&D and acquisitions.

• Award-winning export performance and international reach.
