Aside from the generally unfortunate situation that the combo of OsmoCNI+nanoBTS is not officially supported by anyone, there is also the fact that this particular nanoBTS unit came from ebay in completely unknown condition - a defect can't be ruled out... I have another nanoBTS unit that is also from ebay but from a much more reputable seller, and that one is probably defect-free - but that nanoBTS is for GSM850 band, and I don't feel safe transmitting in that band without a license - looking at my SA, that GSM850 band is much more crowded than PCS1900 around here.
I recommend you to buy from eBay a shielded box and do all your tests inside it even if you have a license to transmit.
Look for Rohde & Schwarz CMW-Z10 or CMU-Z11 which one is cheaper. If you need to test 5G C-band you will need to buy the CMW-Z10 (up to 6GHz).
