I am using a 1.2 meter andrews tx rx dish for my mini bud setup I am trying to squeeze every bit signal I can out of it. Satellites over here are weaker on C band than what you guys have.

Good question, I know what it's purpose is, but to give you an exact theoretical scientific answer i would have to look it up myself lol.
A very simple and obvious answer would be this quote from many on-line articles regarding polorisation ... >>The Polariser section is a circular or square tube with slots or pins along two opposite sides. Its purpose is to change linear polarisation into circular polarisation in the transmit direction and circular polarisation to linear in the receive direction.<<

Thank you for your help John it stinks living in a apartment where you can't have a big dish.

NSS 7 @ 20° West - anybody in Europe receiving this?
First praise the Lord ... then align antenna to 20W.
Looks like 3M antenna needed here, close to Finland.
Global beam coverage America and Europe in C band.
But interesting channels and PowerVu keys available.
MTN Worldwide TV channels.
4128 R
DVB-S2/QPSK
MPEG-4

OK here near Uttoxeter in UK, a little weak but stable on my 1.8Channel Master offset also..
