Thread: Bsc621-2 C/ku Lnbf

Well I am not exactly sure, I just ordered a 1.2 meter Fortec Dish and a motor today from Sadoun and I would like to pick up C and KU and am really interested in this.

For KU I want IA5 and SBS6.
For C Band I am not sure whats up there anymore, As far as C Band Goes I want The Tube thats one I know for sure.

Works GREAT for The Tube!

Watching it here on AMC-3 with Signal quality of around 50% (6' dish remember)!

But that's with a 6' prime focus. I don't think I ever got The Tube in on my 1.2 offset dish. I think there is a fox mux at G11 that is spilling over even though that's 4 degrees away.

I spoke too soon I am getting The Tube on AMC3. Quality is jumping between 38-42% and the picture is breaking up. I had to move my dish a little further east (86.6 instead of 87) to get the most out of signal.

TVU on AMC3 is coming in strong with 55-60% quality.

Ok got my scaler ring yesterday, and just got a call from the freight company this morning that they are delivering the dish and motor today.

Dont think I will get to install it or play with this this weekend supposed to be really crappy weather.

I have not got the LNB yet, but I will order one from PSB once I have the dish working correctly on KU (I will use my Invacom LNB at first then once I am sure I am tracking the arc I will being playing with MICRO BUD.)

I will be interested in seeing what I can get on C Band, and in addition I may even hook up my GI650 receiver to it to scan for Analog C Band feeds (Although I am not sure if the 650 will work with this LNB)

It would be nice later to make a list of C Band channels that it is posible to pick up with a 1.2 meter dish.

You'd have to slave it to the DVB box so the polarity is right. In the default position (hooked the analog directly to the LNB), it should get H polarity

Getting some GOOD results now on Ku-Band!

46% signal Quality on Kuil Fox AMC-4

48% signal Quality on The University Network IA-6

46-53% signal Quality on the Azteca channels IA-6

Very overcast!

55% Signal Quality on ONN SBS6

46-50% Signal Quality on the CCTV channels G3C

Installation Instructions!

See below picture.......

Here are some tips when peaking in the Ku signals using this LNBF........

First find a C-band satellite signal using the C-Band side of the LNBF (C-Band is much more forgiving than Ku), change to a known live Ku transponder on the same satellite, then motor east and/or west until you hit the Ku signal, it will NOT be in the same azimuth position as the C-band signal.
Then re-skew the LNBF to peak the Ku signal, I had to move mine about 2º from the "0" position.
Final step was to adjust the F/D of the LNBF for maximum Ku-Band signal quality.

I also modified the LNBF cover to squeeze every point of signal quality from the LNBF. (Mentioned in its own thread)
Very happy with the Ku results. The C-Band signals did drop slightly after peaking in the Ku signal but it has to be done! And my C-Band signals are still great, and with C-Band not being effected much by rain fade its not a big deal.
