QuadRF Now Crowdfunding on Crowd Supply for $499

Back in June and January, we posted about QuadRF and ScaleRF (previously known as open.space) and their mission to unlock affordable open-source Earth-Moon-Earth (EME) bounce communications for the amateur radio public.

Their core product, QuadRF, is a 4-element coherent antenna tile with built-in SDR and processing on a Raspberry Pi 5. Apart from being able to be chained together to make a massive coherent beam-steering antenna capable of working with EME, a single tile can also be used for C-band (4.9–6.0 GHz) direction finding and spatial signal visualization. QuadRF can also transmit, enabling point-to-point communication and the creation of mesh networks.

Recently, their product was launched on the CrowdSupply crowdfunding platform, and it has already far exceeded their $100,000 funding goal. The QuadRF kit is priced at $499 and includes the required Raspberry Pi 5, a tripod, a 32GB microSD card, and a power supply. The QuadRF Mobile expansion pack costs $149 and lets you take the QuadRF on the go. They are also selling a QuadRF six-pack for $594, although as this is designed for research, it does not include the enclosure, antennas, Pi 5, or phased-array structure.
