QuadRF
QuadRF is a modular four-element beamforming tile that brings full 4x4 MIMO phased-array capability to software-defined radio hobbyists and researchers. Each tile pairs four coherent C-band (4.9–6.0 GHz) Tx/Rx chains with a Lattice ECP5 FPGA and an integrated Raspberry Pi 5, enabling real-time spatial signal processing previously confined to defense and telecom labs.
Built by Santa Barbara-based ScaleRF (formerly open.space), the product was formally named in an April 1, 2026 announcement after a November 2025 Pacificon demo generated viral word-of-mouth. The Crowd Supply campaign went live June 2, 2026, targeting July 2026 shipments. At roughly $399, a single QuadRF tile is a standalone RF camera; sixty tiles daisy-chain into the 240-antenna MoonRF array designed for Earth-Moon-Earth amateur radio communication.
At 30 fps, QuadRF renders a live augmented-reality heat map of every 5–6 GHz transmitter in a room—Wi-Fi access points, drones, handheld radios—overlaid on a phone camera view. A Hackaday demonstration in June 2026 showed the system distinguishing a quadcopter’s two separate video transmitters simultaneously in flight.
Think of it as a radar gun for the full radio spectrum, cheap enough to build into a university lab kit.

Why is it emerging now?
QuadRF is the first open-source 4x4 MIMO phased-array tile priced for hobbyists and universities (~$399), arriving as the SDR community exhausts what single-antenna dongles can do. The Crowd Supply campaign opening in June 2026 marks the window where early content and tooling earn durable authority in a search-empty niche.
Outlook
6-month signal projection and commercial timeline.
Strong niche pull within ham radio and SDR communities; broader mainstream breakout depends on first consumer use cases shipping.
Risk · Export-control classification pending; regulatory friction could delay or restrict international sales.
Analogs · rtl-sdr · software-defined radio · phased array

Competition & Opportunity for term “QuadRF”
Three heuristic signals derived from the tracked queries, the term's monetization cards, and its cluster neighbors. Directional, not audited.
Ideas for term “QuadRF”
Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
Zero direct comparison articles exist today. A first-mover comparison earns the ‘quadrf vs’ query family permanently.
Evergreen explainer targeting the ham radio + SDR overlap audience who just heard about QuadRF at a conference.
Step-by-step build tutorial; captures high-intent ‘quadrf tutorial’ and ‘quadrf setup’ queries at launch.
Natural gap: the official stack is live RF camera mode; a logging + replay + geo-export layer fits an obvious user segment (site surveyors, RF engineers).
ScaleRF explicitly targets educators; a curated lab-pack resource site could earn affiliate or direct revenue from university procurement.
High visual payoff: AR heat maps of RF signals are inherently shareable. Real-world demo outperforms any written explanation for YouTube search.
QuadRF anchors a nascent category. A brief covering QuadRF + emerging open-array projects has no direct incumbent in the SDR newsletter space.
Radar has been $10k+ government kit for decades. QuadRF ships a four-antenna beamforming tile for under $400 in July 2026 — and the entire software stack is GPLv2.
ScaleRF built 240-antenna phased arrays from $399 tiles. The same tech that costs defense contractors millions is now a Crowd Supply project.
The original RTL-SDR dongle ($30, 2012) spawned an ecosystem worth hundreds of millions in content, tools, and hardware. QuadRF opens the same gate for beamforming, fourteen years later.
