200 uv/meter maximum, measured at 3 meters. That works out to about
-46dBm ERP or about 12 milliwatts into a unity gain antenna.
Sorry, brain damage.
The -46dBm should be 10.8dBm ERP
Hmmm... my calculator says P = 12 nanowatts.
Your calculator is correct. My -46dBm is wrong. It was late, I was
multitasking, the phone range, I was tired, etc. Sorry for the
muddle.
+10.8dBm converts to 12 mw.
12 nw is -49 dBm. Why are you still using 12 mw?
The 12mw is correct.
Please show your work.
