W8JI's experience with a horizontal dipole at 300 ft is often quoted as proof 
that only vertical antennas are useful for 160m DX. This is not my experience 
with a dipole with the centre at 320 ft and the ends at over 250'. In its 
favoured directions it is equal to a W4RNL half wave vertical array over a very 
large radial system. It is unsurprisingly not as good off the ends, and quite 
is useless for relatively local communications.
I am also inclined to support Roger, G3YRO, in his use of a low dipole, having 
myself successfully used relatively low horizontal antennas for DX in the past. 
There are most certainly times when higher angles are useful for DX - and 
possibly more frequently than we imagine. There actually have to be, otherwise 
Roger would never work any DX at all. Note, this does not mean that a good 
vertical antenna is not often or even usually better than a low horizontal one. 
Finally, the UK is small compared to many other countries, but it is not 
actually a tiny island. Roger's path to North America is over about 300 km of 
land, and he is more than 10km from the sea in any direction.
