        Professional RF solutions

        Your Trusted Partner for High-Performance Measurement Antennas

        From design to individual calibration, we manufacture every antenna in-house, ensuring absolute precision, superior build quality, and long-term performance stability.

        In-House  Production

        From initial design through CNC machining to final calibration and measurement, everything happens under one roof. No outsourcing, full quality control.

        Complete On-Site Measurements

        Every antenna undergoes individual chamber testing at our facility. Calibration files and measurement reports are available through our Antenna Portal.

        Global Logistics & Support

        We serve R&D centers and laboratories on all continents. Our team ensures seamless international shipping and provides direct technical expertise wherever you are.

        Custom RF Solutions

        Your vision, our expertise. From unique frequency ranges to special mechanical requirements, our engineers deliver antennas built precisely to your brief.

        Featured Products

        The sweet spot of EMC testing.

        Quad Ridged Horn Antenna
        600 MHz – 9 GHz
        Designed for the busiest bands in EMC, the QRH600 reduces antenna swaps, streamlines chamber workflows, and helps laboratories move faster through commercial, automotive, and modern wireless test programs. It brings broader coverage with fewer manual interventions and more productive test time.

        Greater reach across the band.

        Quad Ridged Horn Antenna
        1 GHz – 18 GHz
        Designed for broadband measurement where signal strength matters, the QRH18EC pairs a quad-ridged horn with our patented 3D-printed lens to raise gain across the band. It gives engineers stronger reach at distance, more reliable readings on weak signals, and repeatable setup with integrated bubble levels.

        Broadband without the burden.

        Quad Ridged Horn Antenna
        2 GHz – 18 GHz
        Built for airborne, portable, and payload-constrained RF systems, QRH0218 delivers measurement-grade broadband capability in an exceptionally lightweight form factor. It gives engineers more freedom to integrate, mount, and deploy wideband setups where mass, footprint, and mechanical limits define the mission.

        Latest News

        This June, we are heading to one of the most important events in the RF and microwave industry – the IEEE International Microwave Symposium (IMS) 2026 in Boston.

        From June 9 to 11, our booth 12047 at the Boston Convention & Exhibition Center will be a place to see RF SPIN antennas live. Visitors will get the rare chance to examine selected products from our portfolio in person – the kind of detail that simply does not come across in a datasheet. Our engineers will be on site throughout the symposium, ready to talk specifications, applications, and real-world use.

        Visitors will also see a new RF SPIN antenna on display for the first time. The product is currently in the final stages of development, and IMS 2026 will be its first public appearance.

        Two RF SPIN points of contact at IMS 2026:

        • RF SPIN — Booth 12047: Our main presence at the show, with the live antenna display and the new product unveiling.
        • Signal Solutions — Booth 16089: Our US distributor’s booth, where a member of our team will also be present.

        We are looking forward to a strong year in Boston.

        RF SPIN has earned district recognition as the Innovative Company in the Company of the Year 2025 Awards for the Hradec Králové Region, Czechia. Along with this category title, the company has secured a position among the Top 5 overall finalists for the entire region.

        Innovation for us isn’t a buzzword – it’s how we approach our work every day, especially when it comes to tackling complex technical challenges in the development of our measurement antennas. Seeing that recognized right here at home is a solid result for the whole team.

        The overall regional winner will be announced on June 9, 2026 – wish us luck!
