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?

I haven't bought the thin wires yet. Would it work theoretically?


The purpose of experimentation is to eliminate conjecture --
especially the rancorous conjecture found in this ng.

Hello,

A large loop does receive more signal, but will also receive more
noise/interference. 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.

Best regards,


Wim

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.

Wait! I misunderstood you, at first, huh?

You mean viagra or "antenna-enhancement", huh? stoopid look
