Default A Beginners Question

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

Dale,

I made no shielded loop vs. unshielded loop comparisons. My intent was to
give the beginner the idea that there are different types of antennas, and
by suggesting google, allow the OP to do some research on his own.

That being said, building a shielded loop implies the OP has shielded wire
which can also be used for the connection between the radio and the
antenna. This is probably better then building an unshielded loop out of
speaker wire and using the same wire to connect the antenna to the radio.

Again, I gave the OP the opportunity to do some research.

On the other hand, I used a shielded loop in a previous home as a random
wire antenna was not an option.
