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?

TL;DR

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.

Product
A QuadRF companion app that logs directional signal history and exports to KML for mapping sessions

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).

Product
A university lab kit bundle page: QuadRF + worksheet curricula for MIMO and phased-array courses

ScaleRF explicitly targets educators; a curated lab-pack resource site could earn affiliate or direct revenue from university procurement.

Video
