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.

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

QRH600 (600 MHz – 9 GHz)

QRH600 (0.6 – 9 GHz)

The sweet spot of EMC testing.
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.

QRH18EC (1 – 18 GHz)

Greater reach across the band.
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.

QRH0218 (2 – 18 GHz)

Broadband without the burden.
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.

DRHX34 (500 MHz – 34 GHz)

DRHX34 (0.5 – 34 GHz)

The full spectrum in one setup.

Designed for test programs that stretch from sub-GHz to millimeter wave, the DRHX34 replaces a chain of narrower-band horns with one antenna that stays usable to 40 GHz. It gives engineers one calibration, one mounting setup, and one continuous sweep instead of stitched-together band segments.

Built in Europe, Delivered Worldwide

The Certainty Your RF Projects Deserve

Where your antenna comes from matters just as much as how it performs. Every RF SPIN antenna is designed, manufactured, and measured under one roof in the Czech Republic, then shipped directly to your laboratory. One supplier, one set of measurement data, one team accountable for the result.

Single-Source Accountability

Design, machining, assembly, and chamber measurement all happen in our own facility. No subcontractors, and one team answering for how your antenna performs.

Delivered to 25 Countries

We ship to laboratories, universities, and manufacturers in 25 countries — the same hardware and the same measurement data, wherever the project runs.

Measured, Not Estimated

Every unit is individually measured in our own chamber and its calibration data travels with it, so performance is documented before the antenna ships.

Latest News

We’re exhibiting at European Microwave Week in London, October 4–9, stand B25C. Our newest antennas are coming with us, reaching from 900 MHz at the low end up to 67 GHz.
900 MHz to 8 GHz in a single horn – well past the 6 GHz ceiling of most EMC horns, and built to drive fields, not just measure them.

Our QRH400L and QRH400R antennas have successfully completed independent vibration testing at the accredited laboratory Tiyo a.s. (ISO/IEC 17025 accredited testing lab), verifying their mechanical durability for field use on wheeled vehicles.

Testing followed MIL-STD-810H, Method 514.8, Category 4, with a random vibration profile across 5–500 Hz at 2.13 gRMS, applied for 1 hour in each of the X, Y, and Z axes (3 hours total).

The QRH400L and QRH400R confirm their mechanical robustness for demanding field and vehicle-mounted applications.
