Hello Dan,
I wrote a FAQ based on my setting up the Lightning detector…
It contains information about where I obtained the lightning detector and USB adapter as well as installing the USB adapter and then setting up the detector with WD.
More about getting it all put together and what I used for a housing is here:

Chas posted information about his “Lightning in a Box” setup here:

I spent less than $100.00 USD on everything for mine, including the PVC, wire and ground rod…
