Why would such short verticals effect the 160m RX array.

the issue is more than likely not going to be 'what is the interaction of
the 160 on the 40 ... rather it is going to be what is the interaction of
the 40 on the 160 ... and my guess (after having played with a Hi-Z model of
their 4 element) it will be significant! The pattern will be quite
distorted. That I believe is easier to model as well - just leave the 4
internal verticals un-terminated. I'd love to hear the results.

Gents,
I'd like to build a 40m phased array "inside" my 160m
receiving-only 9-circle and I want to check for any
interaction between the two antennas.
I have the layout in EZNEC 6, but I'm not sure how
to "feed" the 160m array. Do I let it "float", ground the
elements or what?
Also, vice-versa...float the 7mhz array or....?
Suggestions?
Thanks,
Charlie, N0TT
