After having this setup now for the past several weeks, I believe I'm going to disassemble it and return to having a KU LNBF centered and a C LNBF off to the side (http://www.satelliteguys.us/248937-two-c-band-lnbfs-3.html).

While the centered C LNBF worked very well and provided awesome DVB-S2 signal quality I found that the tracking was off on some satellites as I searched the satellite arc. For example when I went to AMC 3 it was always dead on, but when I turned to Anik-F3 for TV Hot or to Galaxy 17 I always had to bump the motor a notch or two to get back the signal.

I'm confused how did you get RTV/TUFF TV/PBJ channels on AMC3? I thought they was in ku band on AMC6?

Due to rain, I didn't get to work on this project. Instead, my wife and I setup our new Casper mattress. I'm going to sleep good tonight.

I opened the Titanium C1-PLL C-band LNBF and all I can say is "WOW". Certainly a very well designed and built product. I'm thinking about upgrading all my other C-Band LNBFs to this model if it performs as well as it looks.

The setup:
  • Channel Master 1.2m Motorized Dish
  • PLL KU LNBF
  • Titanium Satellite C1-PLL C-Band LNBF
  • Conical Scalar
  • 3 Feed Support Arms w/ Custom Brackets
  • Ecoda 0/22 KHz Switch
  • RG-6 Quad Shield Coax Cables
While I was out installing this setup, some young guy stopped and asked if I had any extra large satellite dishes that he could use as shields when playing paintball. :eeek

Starting tomorrow, I'll begin to post the results of the C and KU transponders and satellites received with this setup.

It's real "purdy", but I predict it will soon be disassembled in order to optimize for C-band reception. :(

The feehorn fore/aft position and conical scalar position (in tandem) are both highly critical to receive C-band on a small reflector. I usually will first rough in the reception using the feedhorn only. Slide fore/aft and skew left/right to optimize. Once a signal is locked, then add the conical scalar and slide only it fore/aft and rotate to optimize. Then slide the feedhorn/conical combo fore/aft and slight rotation to optimize, then slide only the conical fore/aft/rotate, then the combo fore/aft/rotate, then the conical, then the combo..... you get the picture! Once you think the signal is optimized, change to a different transponder. Don't be surprised if the feedhorn and scalar placement might need to be changed to optimize. Even panning the feedhorn up/down/left right (aiming into the dish can increase the Signal Quality.

Rejection of interfering signals from terrestrial and adjacent satellite will optimizing the desired signal. It is a balance between optimization on diferent transponders and satellites to get the channels that you really want....

Thanks for the tips Brian. I just had time to get the setup installed tonight. Beginning tomorrow, I'll begin to adjust and optimize.

Looks as though you will have no problem making any adjustments if need be with those nice mounts you have fabricated. Looks great.
That's right, no disassembly required using those brackets. :)

Performed some scans last night without doing any adjustments. A nice selection of channels scanned in having a signal strength over 45%. A new religious channel on Galaxy 19 scanned in having a signal strength of 89%. Just some of the channels are FOX, NBC, COZI and THIS on Galaxy 16, AMG-TV, Dr. TV, LATV and The Walk TV on Galaxy 19, PBS HD and SD on SES3 and a few other channels. Granted, I didn't scan the entire arc or even adjusted the azimuth settings using the motor. Just a quick search when commercials were on during WWE RAW last night.

Too bad you're not selling those bent brackets for the CM/Andrew dishes. You could probably make some money.
Funny you said that, because I was thinking of this just today. :) I started Rinker Technologies about six months ago and was thinking about adding these brackets as a new product. I would also love to offer my customers the Titanium Satellite C-Band C1 and C2 PLL LNBFs, because its such a great product that I highly recommend.
