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

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
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
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
I wanted to explore the possibility of having at least better receive
Monopole Antenna TFM T2FM T3FM
Terminated Folded Monopole Antenna TFM T2FM T3FM The Terminated Folded Monopole (TFM) is a derivation of the TFD, and it is usually implemented as a vertical antenna over an RF ground plane or a radial system

40m Compact 4-Square Antenna Compact 4-Square Antenna – EA5AVL The EA5AVL 40M Compact 4-Square Antenna was designed to provide excellent DX communications on the 40m band
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
Spiderbeam 10-15-20m E' una Yagi tribanda full-size leggera, fatta di tubi in vetroresina e filo
