Marc,
Just for kicks I ran EZNEC for a full sized 2 element beam (24' boom)
at 24 and 28 M height.
24 M SWR =1.306 IMPEDANCE =38 -1.8j
28 M SWR =1.519 IMPEDANCE =33 -0.5j
Interesting that the impedance actually decreases rather than
increasing with height as the dipole impedance plot vs height
predicts.
I don't have a model for the 402CD. It would be interesting to
actually run such a model at the two heights.
Of course, these values are at the feedpoint. What the reading would
be at the shack end of the coax is unknown.
