This question already has an answer here:
Ok guys I can't understand something.
Say that I have this circuit:
Assuming that I apply at the antenna 5V, how can I calculate how much power I will trasmit?
I found on internet that the current that will flow on the antenna radiation resistance, but if for example I go on ebay for try to find antenna no one quote the antenna radiation resistance, so how can I choose my antenna?
Moreover I want to know what capacitor C1 and C2 do in this circuit.
