I've done something different--feeding a vertical tri-angular loop (apex up) 
with ladder line about 4' above a bottom corner.  Most definitely a DX antenna 
with interesting properties.  In domestic contests I could barely hear 
western PA (250 mi.) but TX was strong at mid-day (on 40).  

On multiples of the design frequency, the loop became directional in the 
plane of the loop--not broadside to it.  Mine were cut for 40 meters, and hung to 
favor a NE direction for Europe.  On 14 & 21 MHz the antenna was excellent 
into the Mediterranean (SU, SV, 4X).  At 28 MHz I got great reports from northern 
Africa/SW Asia and the KH6-JA areas of the world.  All this with a barefoot 
Argosy running 50 watts.  

Great return for $15 of wire (including feedline) hung in a tree.
