Why not discuss it with the broadcast engineer
with his long time service at switching on a transmitter every
morning, every day plus turn the lights out.

As I told you once already, the last 30 years of my professional background
was in the field and applications engineering groups of the two largest
designers/manufacturers of broadcast radio and television transmitter and
antenna systems in the US: RCA and Harris.

My experience working directly for broadcast stations was early in my
career, including with a stint at WJR, a 50 kW, non-directional AM station
using a 195° monopole (700 ft high).

And what is your commercial experience in the field of r-f systems?
