Stew and all,

If the K9AY loop (or any other RX loop) is placed this close to existing
structures, interaction is almost guaranteed.  Careful de-tuning of the TX
antennas has a small chance of success.  A workable solution is individual
loops, each oriented so its null is pointed toward the TX antenna to reduce
coupling, but detuning is still recommended.
