You never mention how far away you are from "... Indianapolis 1070kc

reception question.

I'm 70mi from Indy and 120mi from Chicago. Chicago 670kc is reasonable at
night 1070kc out of Indy at night is pretty bad.
Is 40ft at right angles to these signals better that 200ft parallel?

(This doesn't solve your problem, but might give you some info as to
why the reception of WIBC is somewhat difficult.)

Given your distances, then you are somewhere between Indy and Chicago.

WIBC drops their power significantly at night, and also the antenna
pattern shows that the available signal is probably the worst possible
given the antenna :-(. Here is a picture of the WIBC pattern, and
consider the WIBC towers are on the NW side of Indy.

Ya, I see they drop their signal strength from 50kw to 10kw at night. What
would be the best antenna design for this station. I've considered buying a
tuned loop for this frequency but I'm reluctant to drop $70 and maybe not do
any better than my straightwire.
