I finally installed Ku. I feel like a new man. 

I was watching satellite city on  f4/22 when they were
selling a .7 Ku LNB and a Corotor II+ for around $290.
That was a little steep for me and I was going to change
the channel when they mentioned that they also have a 
.9 dB Ku LNB with the Corotor II+ for $215 + 1$ S&H.
That's about what I wanted to spend and I hadn't gotten
any suggestions from the Net where or where not to buy
this upgrade. (I've since seen all kinds of advice)
I ordered it on Friday 9/11. They said I'd get it in 2 
or 3 days. When it didn't come by the following Friday
9/18 they said it must have gotten lost and they would
send another upgrade and if I received both just send
one back. I was very impressed with this, at first. This 
is the way to do business. The customer doesn't get the 
stuff, send him some more. Still nothing came by Wednesday
9/23 so  I called again. They said it was shipped that day
and I should have it by Friday the 25th or Monday at the 
latest. I finally received it on Monday 9/28, 17 days 
after I ordered it. They first guy who said it was sent
out and would send me another one was just bullshitting 
me. When it did arrive it was not the one I ordered. I
ordered one with 65 dB of gain. They offered the Cal Amp
LNB with 62 dB of gain or another one with 65 dB of gain.
With 250 feet of cable I thought I'd get the one with 
higher gain. Oh well. I received a Gardner .9 dB LNB with 
55 dB of gain. A local installer says Gardner is always
the cheapest unit available. I installed it Friday after 
work. I had to grind down two of the nuts holding the 
C band LNB on due to interference with the horn. When I
turned it all on I couldn't find anything on KU. Snow everywhere.
Then I figured out that it would work better if I connected the 
coax from the LNB to the receiver instead of leaving it just
dangling. All the polarities on C band were way off of course,
I did just replace the feed horn. Once I reprogrammed the 
C band sats I found K2 quite easily. Talk about touchy, wow!
My Saginaw actuator only has about 3.5 counts per degree of
dish movement. One count either way and sparkles. Two counts 
and all you see is snow. Even the best position had too many
sparkles. I adjusted the dish down 1/12 of a turn and there 
was no difference. Another 1/12 of a turn on the adjusting nut
and it got worse. So I went up 3/12 of a turn and the picture
is perfect. So I'll keep the Gardner LNB but I don't think
I'll be buying anything form Satellite City again. I forgot to
mention, be careful when you take of the dish electronics
cover. Mine was full with wasps. Everybody asks me why I need 
Ku. Did I really need to spend $230 to get more satellites? 
Didn't I get enough channels already? I just ignore them!!!

Question:
Why does the feed horn have to be pointing towards 10:00 when 
looking towards the dish? Is this to put the polarity positions
at +- 45 degrees which is a good range for the polorizer?

Observation:
There was alot more stuff in the corotor II+ compared to the 
C band only feed horn. The C band feed horn just had a U shaped
wire that was turned by the polarity motor.
