You are correct. It is rubbish. I built it and recorded measurements
because there was so much hype about it. I got exactly what I
expected. A high angle omnidirectional antenna is not a DX receiving
antenna. However if you are into NVIS it actually will improve S/N for
those signals (which is why some people think it is a low noise
receiving antenna). It gets rid of all those low angle signals.

I just tried making a Loop on the Ground to see if it would be any lower
noise than my 6ft 160m Loop up in the loft.
I followed several people's suggested dimensions . . . so 15 feet each side,
feeding it in the middle of the side pointing West with a 450:50 ohm
transformer . . . And it's rubbish!
A local station (in the right direction) on my 6ft vertical loop in the loft
needs a 20dB preamp to bring him to the same level as on my Dipole (and the
noise is 6 to 10dB lower).
But on the LOG he was 30dB weaker, that's WITH the 20dB preamp! So the S/N
would be rubbish. Anyone else tried something similar on 160m?
