There are two REALLY good reasons for having directional receive, 
whether you're on a desert island or not. 

1) QRN will often be 10-15 dB louder in one direction than other, 
and skipping in from great distances just like the DX you're trying 
to work. 

2) QRM will often be 20-30 louder in one direction than another. 
Example -- loud stations from a highly populated country who are 
loud single hop from you won't shut up when you tell them to, and 
wipe out weak 3-hop and 4-hop stations from the other side of the 

In both of these situations, directional receive capability can 
help a LOT.
