Yes, for shortwave a 10-20 foot piece of wire can be used. You do not

to spend a lot of money to get started. If noise is an issue, google
for 'shielded loop antenna'. You can also buy more expensive antennas.

Why would a shielded loop receive less noise than, say, a classic wire
turn
loop?

Shielded loops are less sensitive to local inductive E fields.

I thought there was enough math/data out there that no one any longer
believed this.

From the W8JI page- http://www.w8ji.com/magnetic_receiving_loops.htm
"Folklore claims a small "shielded" loop antenna behaves like a sieve,
sorting "good magnetic signals" from "bad electrical noise".
Nothing is further from the truth! At relatively small distances a small
magnetic loop is more sensitive to electric fields than a small electric
field probe.
