Hello,  
I’ve been wanting to build analyser for RF radiation but get lost in all the different modules/antennas.  
Do you have any recommendations?  
Thanks,  
Vincent

Hi Vincent,

There are lots of analyzers out there but they are all made for specific frequencies. As different frequency ranges would require different antennas. If you want to analyze the general RF you would likely need many devices to capture the different bandwidths. Here is one that will catch some of the common ones though 🙂

Hi Stephen,

Thanks for the link.

I would like to make a Wifi Analyzer that uses a Raspberry pi 3B+

because of the 2.4/5Ghz Wifi Built in.

Can you use this specification on the B+ through python commands (is there a library for searching through wifi networks?)?

Thanks
