Apples and oranges

Your antenna is not a dipole but rather an Inverted V . Inverted V's 
have a significant "vertical" radiation component compared to a dipole

I am not sure how you can compare your performance to the W4RNL 
installation given your 750 miles north of there? Please explain the 
basis for your claim?

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.
