I have to wonder how safe this is

We were out hiking today and I noticed some hawk action near this antenna. Once I trained the camera at the top I noticed what appears to be the start or remains of a nest.

Going to full zoom you can see a bit more detail.

I have no idea of the power of these units but I wonder if the eggs come out hard boiled or get that way in the nest.... or is that not a problem?

Ed I hope they put aluminum foil on the chicks heads
A few years ago I drove from Fort Lauderdale to Key West, I saw many of them on any pole, Eagle nest, Pelican nest. It can be a big problem if the nest connects 2 lines.

Those are either cell phone antenna's or High Speed Microwave ISP Internet data transmission (I had a bunch of them at one time

). Very low power, and very directional (away from the nest). Should be fine ....

There is no danger. A bird can perch right on top of a high voltage line with no danger because there is no connection to ground. That is why you see hoards of birds perched on high voltage power lines all the time.
There is danger for the repairmen because they are grounded through the equipment on which they are standing.

I once worked a site that gave me access to a roof top with microwave horns (transmitters) on it.
From time to time a worker had to go up and pick up dead birds that had flown in front of the transmtters. I never saw a bird get zapped but the dead birds convinced me it did happen.
As for power lines while I never saw it personally I'm told by Vietnam vets that in houses close to power lines they got fluorescent tubes which would dimly light from the power overhead. The people used this to light their homes. I can't believe that is good for the human body.

They usually perch on the highest wire. Typically a ground wire for lightning absorption.

So THAT'S why they are of short stature!

I meant connection of 2 lines via a nest.
