[TowerTalk] 160m 8-circle BSEF array

[RICHARD BOYD]

Or, pare it back further to a standard four-square.  If land is not a limiting factor, you can always do a pair of four-squares to enhance the signal incrementally in the four additional sub-directions.  Hardly anyone would think it would be a good bang for the buck, I don't think, versus a single four-square.

  I was evaluating the simplicity of the feed system for the 8-circle tx/rx
  array (4 active elements per steered direction) compared to the 9-circle
  array (9 active elements per steered direction)  in the 4th edition of
  ON4UN's book Low Band DXing.

  My thought process is this.  The 8-circle array uses a simplified
  broadside/endfire feed to only four (4) of the eight (8) elements...that is,
  four of the elements are left un-fed no matter which direction the array is
  steered. I would anticipate that the four unfed elements would impair the
  gain and FB pattern if left floating.  Would they impair the pattern if they
  were unfed but grounded??

  The difference in gain and FB is negligible between the 8-circle and the
  9-circle.  But the 9-circles feed system is light years more complicated and
  perhaps not worth the additional complexity comapred to a simple BSEF
  network??
