Rename Circular 10750 LNB type to avoid confusion

In North America "Standard" is assumed to mean LO 10750 instead of LO 10000 as it is in TVH. People get confused by the word Circular as Ku polarities here are linear and fail to select Circular 10750 which would work and instead select Standard which is not the correct value for their lnb. Circular or linear is irrelevant to LO setting. 

Also, I've heard from people who have given up on TVH simply because they can't find the settings for C Band. I thought perhaps a little hint might be helpful.
