According to what I have seen on the net so far, the most these do is about 1.4 MW peak power. Your beacon produces more than 4X that, if that is the one you are referring to.

What is so costly to warrant that kind of money, sheer engineering? Engineering is not cheap, especially for leading edge equipment. I think I just answered my own question...
