What mix ferrite does the AES balun use? The original W2DU choke balun
design uses 73 material ferrite, and that does not always work the best on
160 and 80 meters in that application.
I'm not knocking W2DU'S time-tested design; but it's over 40 years old, and
much better ferrites (#31 in particular) have come out since then.
Jim K9YC is absolutely correct about feeding the dipole on 160 as a
T-antenna against a good RF ground, unless you don't care about DX. But
what bands do you want to use it on? And on what band did you experience
the RF problem?
