Reply To: What is wrong with my measurments

Yes, antenna distance is same in both cases – 3 meters.
I just added some more ferrite tiles to chamber which decreased the spike at 179 Mhz by few dBs.

Do I understand correctly – because of my antenna which is very lossy up until 250 MHz, I wont be able to measure anything less than about 40 dBuV/m right at low frequencies?
As you can see in one of the images, when no device is in the chamber the radiation levels are shown as pretty high, and that happens because of Antenna Factor path loss table. At 30 Mhz it is 39 dB..

I have concluded I will not be able to somewhat precise measurements in frequencies below 250 MHz with this antenna..too bad..
