Most (all?) cheap SDR don’t get close to the WiFi range. RTL2832U have one of the best price/range ratios and can detect 24-1766MHz and cost under $20.

LimeSDR is probably one of the better choices and cost $199 without casing as $299 with. I have been waiting for my LimeSDR close to one year now because of the shortage of chips.

You don’t get the raw data (SDR) on Mac like microwave and bluetooth, but you get all WiFi related data. Also broken packages and from other senders.
