Bsc621-2 C/ku Lnbf

It should be the same focal point that's supposedly being used by the current lnb on the 10' dish. A different lnb shouldn't change the focal point.

Not off hand, I would refer to the dish manufactures web site. Let Signal Quality be your guide.

Set it uo for C-Band then enter a LIVE Ku TP. and re peak, you will have to move the dish slightly to catch the Ku signal. Then fine tune the focal distance add skew on the Ku signal. The C-Band signals will drop slightly but you want to peak your Ku signals.

The bigger dish should really help.

Hi Pete
Just read through this thread and you provided alot of tips for setting up the BSC621.Just have a couple of questions that you probably can answer for me.

1-The 621 feedhorn cover has holes in it, should they be sealed to keep out any rain or does it have to breath to keep out condensation.
2-I only have the scalar that came with the BSC and should that be mounted at the same f/d where the KU lnbf was and adjust the lnbf toward and away from the dish for best quality?

11/ I would leave it as is! Any modification will void the warranty. Plus my old trusty ASC421 has the same style cover and has never let me down. And we had some REAL heavy rain recently! (Or so they tell me

)

2/ I would start where Ku was then adjust it while watching the signal quality. That's what I did on my 40" dish. On the Bud the scalar ring is fixed and the LNB is adjusted for F/D

Ok Pete
I did have a very temp arrangement and wanted to attach the unit more securely.the initial tests appeared good.
i will report how the 1.2m and 621 turn out for me later.(maybe much later)

I'm assuming this feedhorn handles both horz and vert polarities.
If so, does it use the 13/18 volt switching arrangement?

**Iceberg** · 08-09-2006 03:34 PM

yes and yes

The DVB box controls the polarity

Anyone having any issues with the KU Freq Hi of 10600 instead of 10750? Does it make much of a difference? I have never dealt with a universal locked KU lnb.

Hopefully I didn't make a mistake in purchasing this lnbf.
