Telamon,

To quote myself again : "Start by taking a Look at some
of the 'commercial products' and Amateur designs"

Yes you are correct Alpha Delta does make some
very good 'commercial products' such as the :
* Alpha Delta DX-ULTRA Shortwave Listening (SWL) Antenna
* Alpha Delta DX-SWL Sloper Antenna
Also the Antenna Supermarket 'commercial' Shortwave
Listener's (SWL'ers) Antennas are very good :
* EavesDropper SWL Trapped Dipole Antennas
* Eavesdropper SWL Sloper Antenna
The RF Systems T2FD Tilted Dipole Antenna for the
Shortwave Listener (SWL) is also a fine example
of a 'commercial' Antenna design along with the :
RF Systems Mini-Windom Antenna and the
RF Systems EMF Electro-Magnetic Field 'passive'
Wire Antenna
Plus there is the Par Electronics End-Fed Shortwave Listener's
{EF-SWL} Antenna is moderate sized but features a robust
design that lends itself to many applications.
