"You apparently haven’t thought very far because if you did you would know that an antenna does nothing but convert electromagnetic energy to electrical. The bigger the antenna, the bigger the voltage to the conductor."

I do know how antennas work.  I think you meant "current" instead of "voltage".

"They use arrays of radio dish antennas to search the galaxy because more antennas means more voltage And when you link MILLIONS of antennas together, you get a much larger voltage."

Again, I think you meant "current", not "voltage" or at least, that's what you should have meant.  In any case, all of those antennas that you refer to are coupled to amplifiers in order to make any meaningful use of the very weak signals.... even with all those antennas.

My mistake. Current is converted to voltage through a resistance. One of the problems I see is handling the voltage and current needed to make it useful.
