Default The dish problem

Hey OM:

Take a 60db gain dish illuminate that with *20 milliwatts of power.
Your ERP is now 20,000 watts.

My question raises the bar, how can you focus 20 milliwatts of EM
particles and waves, to end up with 20,000 watts of EM particles and
waves? And I can bet that it's all those extra particles that are
going to be cooking my turkey.

There's only one way that can happen: the dish is a storage device:
the size and frequency of which determine the storage capacity in this
case the storage capacity gives me a 60db gain. And will always give
you 60db more than you put in.

60db in one specific direction more than if same amount of RF was
dissipated equally in all directions. Correct?
Would not matter if starting with one milliwatt, one watt, one
megawatt.
The beaming effect will concentrate the available energy from all
directions in a specific one.
