While listening on your RX ant try opening and shorting the feedline to your TX
antenna -I bet there is a big change in RX signal and F/B on a given station
will change .
My model of a 2 el active rx array pattern when I change the impedance
presented to the center of my inv vee shows that if that impedance at center of
the inv vee is not above 500 ohms -it will seriously destroy the two el
pattern. ( For quick look I did it for real part -have not looked at pattern
degradation vs reactive loads since my feedline to the inv vee happens to be a
half wave long .)

My K9AY loop (the commercial version from Array Solutions) seems to be
kind of an indifferent performer. I believe it is set up properly. and
I've laid down a radial under each side of the loops, but while it shows
some directivity on high-end broadcast stations, 160M directivity is
limited to nil, signal strengths are rarely better than my inverted-L,
and the adjusting the termination seems to make very little difference.
Any hints?
