Noise cancelers would better be described as interference cancelers.
They work by creating a null in the antenna pattern. They cannot
suppress thermal or undirected sky noise.
As such, if you don't know the direction of the source now, but
successfully "noise" cancel it, you will have established some
information about the direction, and could, in theory, have used other
means to do that more directly.
A possible other approach would be to use a separate, receive antenna,
positioned for minimum interference. My impression is that noise
cancelers only work well at frequencies where external noise and
interference dominate receiver noise, so one should not need as
efficient an antenna for receive as one does for transmit.
Apologies for the off-topic post but I though I'd canvass opinions
before I buy one.
I've removed the OT tag, as this appears, to me, to be on topic
according to the guidelines, which allow more than just Elecraft
hardware related articles.
