[linrad] Polarization question

[Joe Taylor <Princeton.EDU; joe@xxxxxxxxxxxxxxxx>]

Hi Leif (or anyone else who knows),

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.

Suppose they are not well matched.  In other words, suppose that 
the complex gains and signal delays in the two polarization 
channels are not equal.  Will Linrad's polarization-matching 
capability be compromised?  As far as I can see, it still works 
well even with poorly matched feedlines.  I suppose this must 
mean that Linrad solves for a differential complex gain, and 
that over a fairly narrow bandwidth a different delay can be 
treated as a phase shift.

Is this the correct way to look at it?  Can you enlighten me any 
further?
