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 .)

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.
