No evidence provided so far.
Israeli defenses picked on and took out an Iranian drone (a clone of the American RQ-170 Sentinel variant, in the hands of Iran), near Syrian border in 2011.

That incident suggests that Iranian copies are not at par with their American counterpart in LO and otherwise. I wonder why this is the case.
American RQ-170 Sentinel variants have excellent infiltration rates under the right conditions. Newer variants are superior the variant in the hands of Iran by the way.
