This is about confusion of relating antenna radiation theory to power lines. Assuming a straight 100km or even longer possible power transmisson line with 50Hz frequency. What can be said about the ability of 50Hz electromagnetic wave propagation to the space? I found this similar question but didnt find an answer.
I have read part of an answer to a previous question that it wont act as a dipole antenna but rather a transmission line, and the fields will cancel eachother. But I didnt really get what is meant and what is the limitation here. Is that because for radiation to occur the ends of the transmssion lines must be open? An illustrative answer appreciated.
Having asked that I also sometimes read that power lines acting like an antenna when it comes to EMC and radiated noise. So the topic of the power lines radiating “waves” is blur to me. Or when people talk about radiated interference do they also include the fields?
