Comcast Mocks AT&T For Lawn Cabinets While Deploying Their Own → I wouldn't put up with it.

Let them talk to the city and put it on the sidewalk. If I bought a house with something like that on MY property, first thing I would do is get rid of it. (Obviously giving the company a month or so to come do it).

Let them bury it in the sidewalk. Concrete lid on top of it.

In most areas the RoW extends inside(closer to your house)the sidewalk area.
While some areas in california issue a seperate deed in new developments for the easement, the IMPLIED easement exists even if not sepcificly shown on your deed.
willful destruction of their property legally installed in the easement (your property which they are given a right of use) will get you arrested (anywhere from a ticket to a trip to jail) fines, posssible jail time (if you burn it, that's arson, a state and federal crime), AND the FULL cost of replacement/repair.
Plus persons effected by your action may presue civil penalties for loss of use, lost oppotunity, and punitive damages.
shortly you won't own that house anymore (siezed to pay the jugements) so I guess the problem will be solved. (equipment is no longer on your property, i'e. not your property)

And if they are within easement, how would you do that?

I have not seen a VRAD on anybody's front lawn around the south S.F. Bay Area. I've seen a score, or more, of them. Mostly in parking strips, between the curb and the sidewalk. Mostly where there is a property line fence abutting the sidewalk.And let the utility charge you the extra $5 to $10 per month they will need to offset the cost of adequate cooling of the equipment.
