Really? Nothing I've seen said anything about this. I've only ridden in a chopper up to two different radio sites. Didn't like it much. We had an employee who was junior to me, who I had to kick in the *** to get him back in the airplane. The pilot had told us "we need to leave" as weather was closing in.
About 1 minute after we got off, you could not see the mountain anywhere. With all the tower guys and other crap "up there" that's not a comforting feeling.
My boss and I "had words" and then HE went and "had words" with the other employee.
The other site was nicer, a clear day up to "Chewelah Peak" otherwise known as "49 degrees north" There had been an ice storm and heavy snow which ruined several antennas off the tower up there
