MY dipole works allright, though I suspect that the Grove Enterprises one 
will work even better considering that it probably has been designed by 
someone with a EE degree.  Mine is just 14 guage speaker wire, 25ft north and 
25ft south, connected to some RU75 coax via a 300 to 75 ohm matching 
transformer.  Not a thing of beauty, and one of these days I'll have to break 
out the textbooks and build one properly, balanced and the dipole length set 
for the freq range I listen to.
DON"T USE A LONG WIRE!  THey're just murder on Sangean pre-amps, and without 
a spark arrester, they a properly tuned for lightning strikes.  In any case, 
during lightning season, I hook up a small neon bulb between the coax and 
true ground (a pipe froma nearby well).  Whenever the bulb glows, I 
disconnect everything in a hurry.
Hope this helps
Alan
