Just a thought but I used a Delta loop on 40/15m from Grenada with superb 
results. I compared the antenna with a 40m dipole at the same height and 
there was a huge difference both in signal strengths and noise levels. The 
delta loop won the case every time! The antenna is easy to make and cheap 
too, a little height above ground is good if you can get it.  I can provide 
further details/measurements if you would like them! Mine was supported by a 
20ft fishing rod!
