Personally, I was referring to the sizing of the conductors on an AC vs. DC based system that were cited....that's all.
Work, I agree, in the case of the poles, what's done is done. While stringing cable on them for all these other systems is possible....by the time you factor in aerial cable and messengers or the overall cost of bringing in a crew with a lasher to get non-messenger cable up there...the amount spent is going to start becoming very similar to direct bury. Since the OP is in the NE, direct bury, while doable, it doesn't take into consideration the possibility of stones in the backfill material and heaves (even though the backfill is supposed to be sandy for all intents and purposes) and added complexity of weather variables.
Wireless is always going to need a revisit or have far more quirks compared to a direct wired solution.
They're going to have all the utility lines...the WAF is going to be the same, HV, CATV, Telco are all up there already, just adding a couple more, or realistically once they're lashed, a single bundle. Unfortunately, the amount of cable that would need to be left 'just in case' they need to be moved is not going to be fun. Still have to consider pull boxes and handholes.
