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.

TECHNOLOGIES AND INNOVATIONS
Innovative Engineering
At RF SPIN, we never stop improving. Every antenna we design builds on years of in-house development – refining techniques, pushing performance limits, and setting new benchmarks for measurement accuracy.
CUSTOM SOLUTIONS
Antennas Built to Your Specifications
When off-the-shelf won’t do, our engineering team designs and manufactures antennas to your precise specifications. From modified standard models to fully custom builds – we turn complex requirements into reliable, high-performance solutions.
Made in Europe
The Certainty Your RF Projects Deserve
Where your antenna comes from matters just as much as how it performs. RF SPIN products are fully designed, manufactured, and measured in the Czech Republic — using components from verified European suppliers. Every step of the process stays under one roof. That means complete quality control, supply chain security, and reliable delivery.
Supply Chain Security
Every component comes from verified European suppliers — keeping your orders independent of overseas trade disruptions, tariffs, and export restrictions.
Built End to End
Every antenna is fully designed, manufactured, and measured in our Czech facility — with no outsourcing and complete quality control at every step.
Predictable Delivery
A wide range of antennas available from EU stock for immediate dispatch — no customs delays, no overseas freight, so your projects stay on schedule.
Latest News
- Events
The defense landscape is evolving rapidly, and staying ahead is our top priority. Last week, our team attended AOC Europe 2026, the premier event for electronic warfare, cyber operations, and defense technology. By diving into the latest industry trends and strategic insights, we ensure our expertise remains razor-sharp. Our goal is simple: to continuously adapt and deliver cutting-edge defense services that precisely meet the complex, real-world needs of our partners and clients.
- Events
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.
- Impulse Technologies Inc. — Booth 23082: 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.
- Awards
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!
