According to this:


The company which designed and built the dual trideco antenna system at 
Cutler had to guarantee >50% radiation efficiency, and they achieved an 
antenna radiation efficiency of 74.9% when using the 6 panel trideco.

When I read this, I was truly amazed.

Although, this site:


does say that with 2 MW input, the ERP is 1 MW, which would indicate at 
least 50% radiation efficiency.

I am still amazed.

Very true indeed.
