Using loops in combinations.

    Most of us have tried loops singular. Has anyone tried loops in combination? Have used a short length of plastic electric conduit with a ferrite rod held,

      Have used a short length of plastic electric conduit with a ferrite rod held, coaxialy, in each end.
      Wound a short coil on the outside of the conduit over each ferrite rod.
      Connected the inner end of one coil to the outer end of the other coil, bought the left over ends together at a tuning capacitor.
      Tunes ok, however the expected null occurs over only a few degrees of rotation and is very deep.
      Conversely, the "acceptance angle" (whatever the opposite of null is) broadens.
      Any comments, experience or help appreciated.
