Re-sending just to make it CLEAR that its the LINEAR pol that's the issue. I
don't know another or better way to say this.

This is very poor choice. Faraday depolarization will de-polarize all but
the closest possible LP microwave interstellar signals. This will corrode any
modulation and dilute the SNR received at a given LP.
CP is not so affected.
C'mon Paul; this I DID expect you to know;-)
