With a scalable architecture, you can pick an array size and grow later.

QuadRF: A Single Tile 4x4 MIMO SDR
13 cm
Price: $49 - 99 (TBD)


QuadRF is a modular 4x4 MIMO beamforming tile built with an open antenna architecture that moves software-defined radio beyond time and frequency, into the spatial domain.

Mini:   Starter Phased Array

Mini Array
52 cm

The Mini is composed of 18 QuadRF tiles (72 antenna) + interconnect structure


Price: $899–$1,499

Overview

A compact, budget-friendly phased array that already delivers substantial directivity. It’s designed for experimentation and hands-on phased-array learning. Add extension boards later to grow the array further.

Applications

  • Cooperative hobby FPV/video-link experiments, robotics communications research, and educational link-alignment demonstrations, subject to applicable radio rules.
  • High-gain and directional links; repeater backhaul
  • Communications with low-Earth orbit amateur satellites

Performance & notes

  • Array size: 18 tiles (72 antennas) • Beam steering ≈ 60°
  • Expected array gain: ~34.0 dBi • EIRP: ~52.6 dBW
  • Low-latency beamforming; coherent clocking across QuadRF tiles

Power supply: 12 V DC (≈450 W peak)
License: 🪪 Amateur Radio (Technician+) to operate, country restrictions apply.

Moon: A High-Aperture Phased Array

Moon Array
100 cm

Composed of 60 QuadRF tiles (240 antennas) + interconnect structure


Price: $2,499–$4,999

Overview

A high-aperture array built for Earth-Moon-Earth (EME) experiments and radio astronomy. Delivers the beam-forming gain and EIRP needed for moon-bounce.

Applications

  • EME (Moon-bounce)—transmit and hear your echo or talk with others
  • Milky Way C-band imaging; RF sky surveys
  • Atmospheric and ionospheric sensing experiments
  • Advanced phased array research

Performance & notes

  • Array size: 60 tiles (240 antennas) • Beam steering ≈ 60°
  • Expected array gain: ~39.3 dBi • EIRP: ~63.1 dBW
  • Coherent distribution network; timing holdover and GPSDO-ready

Power Supply: 12 V DC (≈1.5 kW peak)
License: 🪪 Amateur Radio (Technician+) to operate. 1 per person. Country restrictions apply.


* Not intended for radar applications. Core functionality needed for radar not included due to export control restrictions.

A New Frontier for Ham Radio

Bouncing signals off the Moon—known as Earth-Moon-Earth (EME) communication—has long been the ultimate challenge for radio amateurs. It required large antennas, expensive equipment, and accurate manual pointing and tracking. We try to bring this down to Earth, providing all the tools needed to experience the thrill of space communication, with an software-defined phased array.

Hardware

Expected to ship: July 2026.
