Many UAVs are flown under remote control. Radio direction finding may

Good point, few countries have enough satellite bandwidth to manage
UAVs the way the US does, so unless Iran is buying bandwidth from
someone else, they'd have to be RC controlled UAVs.

That would make the controller VERY vulnerable to counter fire and
would severly limit range. It would also make the control of the UAV
somewhat easy to jam, or even commandeer.
