Shortwave Antennas Loop
Here are some photos of the Shortwave Loop Antenna assembly to help you with putting it together

Skywire Loop Antenna, N4KC
Below is a rough diagram and some photos of my skywire horizontal loop antenna. It is roughly 475 feet long and fed with 450-ohm ladder line

The Carpet Loop A High Performance Indoor SW Antenna, N1KGH
Active antennas are expensive, apt to generate as much noise as signal, and are prone to overload

Two Tube Doerle
This radio uses two #30 tubes and operates on batteries. It has shortwave coverage in two bands, 4.8 to 7.5 MHz and 7.3 to 12.0 MHz using plug in coils
