It's more than antennas. There's also propagation. You're 700 miles ESE of me, which gives you a path to EU over less of the auroral zone. AND there's noise, which has been increasing over time. My first years in W6 were more productive for CW on Topband than now -- I have a dozen or so

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
