Increasing the size of the AM antenna
Suppose I buy a roll of thin wires, install multiple hooks at the
corners of my rectangular room, then wrap the wires along the hooks, then connect the 2 ends of the loops into my hi-fi. Would that make a great AM antenna? Would it work? -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

You should optimize for best signal to noise ratio. Often, larger does not mean better. When you make a loop as large as your room, the wire may run close to mains wiring or equipment that generates interference (that may result in bad reception). You can better make a small portable loop that you can move around to find the sweet spot/orientation for best reception. You can use whatever insulated copper wire to make the loop.

Thanks One example that's fairly easy to build. You will need a variable cap for tuning. I don't know what type of antenna you have on the stereo, but one of those loops can be fed passively just orienting it close to the loop or loopstick on the stereo. If it has no antenna, but connections for an AM antenna, you can using the coupling loop built into the loop antenna, and run coax or whatever to the stereo. http://home.comcast.net/~nm5k/loop5.jpg |
