[Antennas] Isotropic

Fri, 12 Dec 2003 20:34:23 +0000

FYI-
Websters definition is confusing with respect to antenna applications.  Try 
a technical manual, basic antennas 101 or ask someone who works with 
antennas. I am amused by an attempt to help when the answer is more 
confusing than the question.

isotropic

\I`so*trop"ic\, a. [Iso- + Gr. ? a turning, fr. ? to turn.] (Physics) Having 
the same properties in all directions; specifically, equally elastic in all 
directions.

isotropic

adj : invariant with respect to direction [syn: isotropous] [ant: 
anisotropic]

Comment...  Lets be practical,  it means  the antenna perfrmance in free 
space....  which means...make it higher   than is practical, but.. is a 
reference point, as a perfect radiator, without  influence by surrounding 
objects or ground effects.
  Can we agree on this ?
  i hope so

By definition, an isotropic is one that has equal radiation in all 
directions--wherefor
the need for a model?
