[Lowfer] EAR on e-probe and EWE

[Michael Sapp]

HI All:  Here is an ARGO screen capture of EAR on my e-probe with a low-Q 1060kHz LC shunt across the e-probe whip input to null the middle of the BC band. I have 50 KW stations at
1020 and 1080 kHz 4 and 5 miles away, and another 33 KW  worth of 5KW AM BC stations within 10 miles...

Peak Background noise -60 in ARGO QRSS30


This is my NW EWE antenna

Notice the peak background noise is about 6 dB lower on the NW EWE antenna.   


The e-probe is located up about 25ft in a Magnolia tree and behind a 70ft Blue Spruce, which offers some shielding from my 160M-HF ground plane antenna (MFJ-1793)
