Yesterday, I decided to setup the damaged GeoSatPro 1.2M dish for C-band on Galaxy 23 @ 121°W. After I locked EchoStar 9 using a regularly KU/Linear Lnbf, I then swapped it for a DMS741U C/KU LNB, but for the life of me, I could not get any signal from the KU side of the LNB (I tried independently with/without the C/KU jumper cable), but I was able to pickup C-band with it. After about 1.5 hours trying to lock on the KU side of the signal without success
( but to my embarrassment, I realized that I was using a 10750 for a LO instead of 10600/9750. I will try the KU side again later).
I then tried the C-band and quickly picked up STO transponder 3707H 5632 SR. The sports Man Channel, 3724H 3002SR, and a shopping channel also a Horizontal transponder. The only one that was stable was the STO channel; the remaining two were cracking up occasionally! But my worst disappointment was not being able to lock on the Baby Channel 3889 H, 13020 SR. No matter which way I moved the LNB, I would only get a fluctuating 0 to 13 Quality 
Adding either the Conical or flat scalar didn't help! It should be noted that on this setup, the flat scalar didn't improve signal much, but the Conical improved quality from 10 to 25 on a Viewsat Ultra meter. But on the Coolsat 5K it is a 50 to 66 or so.
Since, It was getting late and I wanted to watch the Cband stuff in 2 locations, I took out the DMS741U and replaced it with a GEOSATpro C2 (LNBf position 0=3 o'clock or 9 o'clock and my skew is 40 for my location). GEOSATpro C2 quality is 2 or so points lower than the DMS741U. Another disappointment is that I was never able to lock on any V transponders. Why, I don't know! I also noticed when peaking he dish, I had somehow picked up Jewish Life TV on 4176H 20000SR......on 123°W, and when I leaned on the dish to the right (standing behind the dish) it has quality and when I leaned to the left quality dropped to 0. Considering my location should, I be doing better than my currents results?
See LNB pictures
To cover the scalar from the elements, I used a cover lid from a mixed snack plastic can (fits as if it was made for the scalar Cone). Quality does seem to be affected.
