Sir Joe!
As far as I have understood Linrad tries to combine the incoming
spectrum of two
antennas in order to reach a signal vector maximum for each spectral component.
Thus it does not seem to matter (at least for that summation process) what the
absolute length of feed lines or relative
Hi Joe, Zaba and all,
Ideally, I suppose, with an xpol antenna one would like to have
phase-matched preamps for the two polarizations and equal
electrical lengths for the two Rx feedlines.
Sure:-)
Suppose they are not well matched. In other words, suppose that
the complex gains and
Thanks Leif for all explications!
As such it is clear that in stable conditions (no polarization
change) a signal
emanating from one source must be able to show a fixed polarization state
irrespective of its spectral content, but any offset from the real
value is due
to feed line length
Leif, Zaba, and all,
Many thanks for the clear explanations!
