Hi Elysia,
> here's a huge transformer 2 miles from the lodge.
Transformers are short range magnetic fields.
Are there large Power lines within one mile?
> if they're anything like hi-transmission power lines
Not the same.
> how a transformer might affect someone
Stay out of the magnetic field it generates. Depending on how many amps
of current it runs, can be as little as one foot, to as far as 20 feet,
in my experience.
> Do helicopters go 2.5 miles up into the air
No.
Aircraft that are not pressurized, stay below 10,000 feet, that is 2 miles.
Helicopters usually fly near the ground, 500 feet is typical.
So any helicopter flight that goes over houses, with WiFi and Smart
meters, will be exposed to those frequencies. I would also avoid flying
low, as cellular towers send out their beams low to the ground, to serve
customers on the ground.
