The original quote for a single tile was $50-$100 They came out at $500 Being off by a bit is fine. Being off by 5x to 10x is.. Yikes.
Prices have gone a little insane in the last year though too to be fair to them.

Do share some more details please

#24if it can spot/track drones that is a marketing opportunity for airports around the world that have to deal with drone nonsense which shut down flights for days
Yes, primary radar has been useful for detecting airspace incursions since 1939. Nothing new here.
The difference with this kind of tech, though, is tracking down the operator.

Phased array antennas (in use since the 1960s) and AESA (in use since the 1990s) are very mature tech that RF engineers are well aware of.
This gizmo is primarily interesting that it's pre-packaged at a price that hobbyists can afford.

#26It should be more specific, it spots RC drones operated on ~5.8ghz, it won’t spot RC on 900mhz, nor cellular enabled ones.
Is that a limitation of the antenna? I though QuadRF uses SDR so can see many frequencies, not just the wifi things like ESPARGOS [0] From documentation, QuadRF: Operating frequency range of 4.9 - 6.0 GHz (C-Band). 0. https://espargos.net/
Not the antenna, unfortunately, it only operates on the range of 4.9-6ghz.
It would be great to have a wider range like other SDRs but of course the cost will increase exponentially.

Please elaborate.
There are literary step-by-step videos on how to build these.

#28Sigh, fine. I will buy another radio gadget on crowdsupply.

#29I wonder if this tool can help with EMC compliance testing. My TinySA needs an LNA, so I wonder if this has the required noise floor.
I don't see any professionals turning to this for EMC/EMI testing, they already have all the test equipment for that job.
