That's interesting! I thought that if you for example have a 50w RF transmitter, taking 40w from it would make it act as a 10w one for the other devices around it.
Thx for the explanation :3
It you could build a 40w antenna sure, but it’d basically have to be a dome surrounding the transmitting one at that point.
