MTM Scientific Shortwave Loop Antenna Kit
Shortwave loop antenna KIT allows you to build a tuned loop antenna for indoor reception of shortwave radio broadcasts over the frequency range of 4 MHz to 15 MHz

Randmon wire antennas, KC7NOD
This is probably the oldest SWL antenna design. It is often called a long wire though a true long wire is cut to a specific frequency and is at least one wave length long at that frequency

Random wire antenna for shortwave listening, VA3STL
it would be best to use a 9:1 transformer to match the random wire to the 50 ohm feedline

Receiving loop antenna for 160 meters band, N8MR
I wanted to explore the possibility of having at least better receive
