Inverted-V versus HF multiband vertical on 40m WSPR RX

 

Curious about how the vertical (blue) receives compared to the inverted-V (red). The vertical is theoretically a DX antenna and should receive good signals from low angles. However, a vertical also picks up much more noise compared to a horizontal oriented antenna. Overall the vertical did not pick up half the amount of spots the inverted-V received.

Again it seems the SNR is better on the vertical at night. What causes this is unknown. My guess is that there is less noise from the neighbourhood.



The inverted-V proves to be a good DX antenna once again.


The vertical is not that bad. Unfortunately a lot of bogus spots again. I think the computer causes this. Unfortunately I have no better computer for the second station at this moment.
