The power of the carriers was 50-dBm and the test distance was 0.25-m. The measured PIM power level was below the required specification value (-105-dBm) for mesh tension values ranging from 2.5 to 60 grams/cm. The minimum PIM power level (-129-dBm) was detected for a mesh tension of 30 grams/cm. In the antenna operative range of tensions (between 5 and 8 grams/cm) the PIM power level can be assumed constant around -117-dBm.
