SIRIO Antenne

What SIRIO Antenne does

SIRIO Antenne s.r.l. is an Italian family-owned antenna manufacturer founded in 1972 by Giuseppe Grazioli in Volta Mantovana (MN), Italy, and currently managed by his daughter Stefania Grazioli. The company designs, manufactures, and sells professional and amateur radio antennas covering the frequency spectrum from HF (3-30 MHz) to 6 GHz, with product lines spanning CB/10m HAM, VHF (airband, marine, TETRA, 2m amateur), UHF (TETRA, ISM/LoRa/SIGFOX at 433/868/915 MHz, 70cm amateur), cellular (2G through 5G including MIMO), Wi-Fi/WLAN, and ADS-B aviation antennas, plus RF accessories (connectors, cables, vehicle-specific brackets). R&D is supported by an in-house electromagnetic modeling capability using CST Microwave Studio, an anechoic chamber (1-50 GHz), CNC machining for prototyping, and a quality department with climate testing. Approximately 90% of manufacturing is performed in-house across four production facilities totaling ~6,000 square meters, with ISO 9001 certification maintained since 2004.

The company operates exclusively through an indirect go-to-market model, selling via a distribution and reseller network that covers all European countries, the Middle East, and the United States, with no direct-to-consumer sales. Pricing is not publicly disclosed and revenue is generated primarily through hardware sales of standard catalog products and accessories, with separate Italian and international distribution contact channels. Distribution depth is reinforced by automated vertical warehouses enabling 12-24 hour domestic delivery and 3-4 week international order fulfillment on over 2,000 stocked components and 700+ finished product codes.

SIRIO has secured high-profile scientific contracts that elevate it well above a typical SME antenna vendor: a 2022 tender win to supply 78,000+ SKA-Low low-frequency antennas (50-350 MHz) to the Square Kilometre Array Observatory (SKAO) for the world's largest radio telescope array in Australia, developed over five years with INAF; a P-band (300-420 MHz) receiver for the 32-meter Noto radio telescope in Sicily; and 480 Yagi-Uda antennas for Italy's Croce del Nord radio telescope under the PNRR 'Next Generation' program. Recent product launches (2023-2024) include the patented SO 5G wideband dipole, MIMO 5G 2x2, LPA 5G ceiling and side-mount variants, SMP 5G panel antenna, and ADS-B mobile/directional antennas, positioning the company for next-generation cellular, Wi-Fi 6, and aviation connectivity markets.

Core offering

SIRIO Antenne designs, manufactures, and distributes professional and amateur radio antennas operating from HF (3-30 MHz) through VHF, UHF, TETRA, cellular (GSM/UMTS/LTE/5G), LoRa/ISM, and Wi-Fi up to 6 GHz. The portfolio spans base station, mobile, marine, aeronautical, cellular/LTE/5G, Wi-Fi, and ADS-B antennas, plus accessories (connectors, cables, brackets). The company also undertakes custom antenna projects for scientific institutions, including 78,000+ low-frequency antennas for the SKA radio telescope and specialized receivers for INAF.

Product overview

SIRIO Antenne is an Italian antenna manufacturer with over 50 years of experience producing professional and amateur radio antennas. The company operates as a hardware-only manufacturer offering a comprehensive portfolio of RF antennas and accessories organized across multiple frequency bands: HF (3-30 MHz) for CB and amateur 10m bands, VHF (30-300 MHz) for airband, marine, TETRA, and amateur bands, UHF (300-3000 MHz) for ISM/LoRa/SIGFOX bands, and Cellular (2G/3G/4G/5G) for mobile communications. The product lineup includes omnidirectional and directional antennas, MIMO configurations for modern cellular networks, panel and dipole designs for base station applications, and mobile/magnetic mount antennas for vehicles. Supporting product categories include connectors, adapters, RF cables, mounting brackets (universal and vehicle-specific), and spare parts. The company also participates in custom projects for scientific institutions including the SKA (Square Kilometre Array) radio telescope project and INAF (National Institute for Astrophysics) collaborations, developing specialized antenna systems for radio astronomy research.

• SKAO (Square Kilometre Array Observatory)coreStrategic or Co-development Partner · 1 January 2022Sirio Antenne won the tender in 2022 (after nearly 5 years of work since 2017) for construction of 78,000+ SKA-Low low-frequency antennas (50-350MHz) for the international SKA radio telescope project. The antennas will be installed in Australia as part of the world's largest radio telescope array. Sirio Antenne was involved through INAF in creating prototypes and testing materials, bringing antenna construction to Italy.
• INAF (National Institute for Astrophysics)coreStrategic or Co-development PartnerCollaboration between Sirio Antenne and INAF (Italy's leading public research institution for astronomy and astrophysics) for developing antenna systems for radio astronomy research. Projects include: (1) P-band receiver (300-420 MHz) for the 32-meter Noto radio telescope for space debris monitoring and observation of pulsars and fast radio bursts; (2) 480 Yagi-Uda antennas for 'Croce del Nord' radio telescope in Bologna as part of PNRR 'Next Generation - Croce del Nord' project.
