Help with chaparral LNB

[rdel]

Hi Guys
Can someone tell me the difference between a corotor and the corotor II lnb?
I have a chaparral corotor ( or C II ) I'm going to sell but I don't know the difference
for listing. I'm unloading my c-band dish for a mini c-band ( I allready have the dish) and I'm looking to get a bsc621 to play with.
Thanks Guys

Corotor is a type of feedhorn, it's not an LNB, but the LNBs do attach to it.

The Corotor has a single port for one C-band LNB.

The Corotor-II has two ports for both a C and Ku-band LNBs.

Both types of Corotor feedhorns use a polarotor servo motor (the blue box mounted on top) to set polarity.

Actually, the corotor is the older version of the C/Ku feed. The polarotor is the C-band only feed.

I believe you're both correct in a way. The servo motor used to adjust skew/change polarity used to be refered to as a polorotor, at least that's what I've always heard it called. It looks like Chaparral has always had a feehorn under that name. Perhaps it's one of those things where the name of the company to first manufacture the product becomes it's "household" name. Can't think of a good universal example.......but one that I'm familiar with is Ski-Doo.......people talk about going "ski-dooing" when they really mean snowmobiling. Ski-doo being the name brand of the first snowmobile.

My 2cents.

Here' are the feedhorn descriptions from the Chaparral Montery manual (I should have looked here first!)... http://img208.imageshack.us/img208/7470/feedxy1.gif
