New to the forum and looking forward to learning from the knowledge on this forum....
My first quest is to understand the rating of Radio Transmitters, I work with radio units that transmit upto 2.5 Watts. They are simply black boxes to me and although I understand what they do in my day to day job of sending commands and indications to automated High Voltage Circuit Breakers spread across a 10 mile radius. it confuses me is that how does 2.5 Watts of power send a signal to another radio reciever upto 10 miles away, when 2.5 Watts in a filament lamp would barely glow. Then thinking about TV/RADIO Broadcasting the main Antenna near to me uses 1000 KW.
If anyone could in lamens terms, explain to me how a radio signal transmission can have a power rating and where is that power/energy used I would be very grateful.
I hope my rambling makes a little sense
