First screenshot NW beam
Second screenshot TCI 530
Same scaling of the waterfall on the kiwi menus (0,-10,auto)
Used 'save waterfall to JPG' from the kiwi menu

To compare the NW antenna at kfs with the Omni TCI530 at the same kfs location, I took another screenshots:

I used the waterfall scaling as follows: scale = Auto, ceiling at 0 and bottom at -10 in the kiwi menu




And here is the TCI 530 = it turns out, that both antennas are seriously influenced by some jamming NOISE.....




I think it is worthwhile to check the signal distribution to the kiwi's in detail!
I cannot believe, that the technicians of the kfs station do not realize failures of that dimension. The only reason they do NOT realize it is because at their end of the signal distribution, this problem do not exist....

This screenshot is from  11:09 utc on the north west LPDA
The S-meter is from a Japanese station (JM7OLW) always putting a big signal to California on 40m...on don
However the signal at kph on the TCI 530 is 20db stronger !!! There is definitely something very wrong ! How is it possible, that the technicians at kfs commercial
station do not realize this !

Here is the comparison to how the spectrum looks like at kph TCI 530:



The kfs antenna needs urgent repair - it is seriously broken and effectively unusable!
I have not checked the other antennas at kfs (yet)...
