SIRA RADIO SYSTEMS

What SIRA RADIO SYSTEMS does

SIRA Radio Systems S.r.l. is an Italian manufacturer of broadcasting and telecommunications RF equipment, founded in 1977 in Burago di Molgora and now headquartered in Basiano, near Milan. The company designs and produces a full portfolio of FM, VHF, and UHF antennas, RF combiners and bandpass filters, and coaxial components (switches, splitters, directional couplers, rigid lines), serving television and radio broadcasting operators and telecommunications operators worldwide with installations in more than 120 countries. Its technology base includes custom-engineered antenna architectures — notably a broadband wraparound UHF antenna developed with the University of Milan for 700MHz spectrum clearance projects — and a state-of-the-art in-house test range at the Basiano facility for radiation pattern and VSWR measurement of full antenna systems prior to shipment.

The company operates as the Italian brand within the Kathrein Broadcast Group, having belonged to the Kathrein family since 1992, with the global broadcast business carved out into the Kathrein Broadcast Group in 2019 and the Italian entity rebranded SIRA Radio Systems S.r.l. in March 2021. The SIRA portfolio is described as complementary to the traditional Kathrein Broadcast offering, allowing customers to purchase both brands through a single channel since 2016.

The business model is enterprise B2B direct sales of both standard catalog products and custom-designed project-specific solutions, with hardware sales as the primary revenue stream and installation services as a secondary stream. Pricing is quote-based, contracts are multi-year, and products are documented with downloadable PDF catalogues and datasheets. Customer engagement occurs through the company website enquiry forms, industry events such as IBC, and detailed case histories documenting installations for broadcasters including Arqiva (UK), RAI (Italy), and operators in Portugal, Canada, and Indonesia. The company is ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified.

• University of MilancoreStrategic or Co-development Partner · 1 January 2015SIRA collaborated with the University of Milan to develop an innovative Broadband antenna solution for the 700MHz clearance project. This partnership led to the development of a prototype that was range tested at SIRA's facility near Milan with measured results matching theoretical analysis.
• Kathrein GroupflagshipStrategic or Co-development Partner · 1 January 1992Since 1992, SIRA has belonged to the Kathrein group, operating independently under the SIRA name.

• ArqivacoreOthersArqiva commissioned the unique broadband wraparound antenna for the 700MHz clearance project in the UK. This custom-designed antenna allowed support of both pre- and post-clearance transmissions on a single antenna, significantly changing the scope and complexity of the UK 700MHz Clearance Programme.
