Even an ordinary SuperLoop, Flag, or Kaz should be able to dump WTAM down to nothing.
I'm a similar distance from WTAM in the opposite direction. SuperLoop nulling 255 deg. / peaking 75 deg. largely clobbers WTAM to leave two co-channel Colombians, a Cuban, and Radio Globo from Brazil. TA's such as Spain 1098 are helped. If I moved the antenna to null at 270 deg. (due west), I'd scrape up another 5 or so dB or WTAM nulling.
These antennas are not hard to build and need less amplification than the DKAZ.

I don't have the greater than 100 ft. / 30m unobstructed spread in any of the directions that would benefit DXing here. DKAZ here isn't going to be likely. If I did put one up, I think one end or the other would be too close to noisy power lines. Also, for that reason, arrays are definitely out.
At least the two SuperLoops I have here (at a right angle to each other) do reasonably well.
If you can install a DKAZ, by all means do so. It would be great.

Neil:
I realize some form of aerial phasing would be beneficial in eliminating unwanted interference. And, I've thought seriously about erecting a DKAZ array, but so far laziness tends to intervene.
