Back in the late 90s, there were a pair of articles in QST about a receiving antenna for 80 and 160 that rejects local noise. The antenna was low and horizontal, it was exceptionally quiet even in a somewhat noisy location, and it had a very high reception angle. I recall that the authors

And from the Northwest I have a slightly different observation of horizontal/vertical questions. What I have noticed is this. I more or less equate Horizontal antennas with high angle and vertical with low. The EU stations are usually mostly looking West into the setting sun. The East coast

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

Re: Topband: Topband resource vertical vs. horizontal

2020-01-15 Thread David Olean
I was always intrigued by the success of our "Down Under" friends in VK6. They tried vertical polarization and it was horrible. They had much better luck with horizontal wires.  I think this had much to do with the gyro frequency.  It depends on where you are in the world.  I am about 30 miles

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
