just a thought will it work?
I am going to use this as example as it will be easiest to understand.
I want to increase reception of a broadcast radio .54 MHz - 1.710 MHz.
I could wind a coil say 12 inch in diameter and attach a variable capacitor. I know it works without power. I could make bigger loops etc. not what I am looking for here.
If I take the same 12 inch loop, same variable capacitor and attach it to a an rf amplifier to increase the signal. easy enough. But what if I put the loop outside and preamp outside the house and use coax to run inside and then attach another loop inside the house attached to the output of the rf amplifier? I know it will work. But what if you beef up the preamp even more say to 100 mw (just using this value for conversation) of output considering you will have to do a lot of amplification to get there I suppose, but the final thought is how much of a distance can I get between the radio and the loop by doing this. The idea is to cover the whole house as you walk around with the radio inside the house. This is in the country so no houses next door. Or is it just a useless idea? maybe best just to make a front end receiver and re-broadcast the signal. It would be a fixed signal 1.460 MHz am. The idea behind the idea is to increase the range of the output from coil to radio. So you dont have to be close by the output loop to make it function correctly.
