They're definitely passive reflectors and you may well be right that they're for TV. I suspect however that they're for microwave radio-relay and probably carry the telephone trunks out of the town in the bottom of the valley. I saw several reflectors like this in the Balkans some years ago and they were all part of the (rather elderly) telephone network. Their great advantage is that they need no power (particularly important in mountainous terrain) and require next to no maintenance. Even if these particular ones are no longer in use it's probably not worth the cost and effort to remove them.
