I must confess I'm one of those who doesn't necessarily feel disturbed while spotting one of these cabinets on top of a mountain. It's my job. I'm among those people who spend ten hours a day - most of which sitting and talking in endless meetings - trying to make these telecom equipment work as the "customer wants".
One could argue what a smart-phone is necessary for on top of a hill. He's got a point. But there are many others who are in the need of a permanent connection, where ever they are, 7x24. For them (and few others public interest services) these boxes and antennas are for and, yes, there are times I feel proud to spot them and tell my kids what they're for and that I'm one of those guys who made what's inside.
