Using BSC621-2 C/Ku LNBF

Reinhold · #1 (**permalink**) 07-12-2006, 08:40 AM

I bought the above LNB (available from sadoun) and the holder from sadoun and installed them yesterday.I do not get any stations.The LNB came with a ring,does that need to be installed? How far forward does the LNB need to be? Any suggestions as to installation of this LNB would be appreciated.

Here are some pics of my install. Hope it helps.

Scalar ring has to be installed to properly illuminate the dish. I am using one specifically made for ofset dishes that I got when I ordered another c lnbf from someone else.

THanks for your help.
I am having problems lately with betting on the forum,so I was not able to give a Direct reply.

Is this the lnbf with the built in DiSeqC and circular ability? If so I have one that I have not put in yet. I am mounting mine to a 8.5' mesh dish for a dedicated dish for 40.5 C Band circular. I will be mounting in standard big dish fashion ie: using the scalar ring. If you are set flush to the face of the ring you should be decent for a start.

This beast has odd LO which makes it unusable with 4DTV receivers. Are you trying to mount to a solid small dish as VJ has or normal big dish config?

I am mounting it to the 120cm solid dish.
I mounted it like VJ shows with the ring and without it right to the end of the LNBF.No signal of any kind.

do you have diseqc correctly setup for c and ku? Try it on Ku first, make sure it is working. Also make sure that Lnb is rotated like the one on my picture in order to get the polarities right.

Hi vj.
Are you saying I need To rotate until I get signal with a TV on the roof?
If that is so I will wait till the weather is more cooperative.
It is already 80 at 7AM here in VA.
Thanks again.I'll keep trying.Reinhold.

If you are setting it up as a linear you have to have the skew set which would be rotation of the lnbf. I am setting mine up as circular so in theory it should not matter for me.

One thing that would matter for you though is how you insert the dialectric plate. There are 2 slots for it. One is if you want all L and the other one is for all R.

Same as with any other lnb, skew has to be set at 0 for motorized setup and if it is not motorized, you will manually have to adjust the skew for each satellite depending on your location. In my case (since I have motorized 1.2 dish) the way you see the lnb rotated seems to be 0 skew. I'm not 100% sure since markings on the lnb are vague, but it seems to match all the polarities and get the best signal.

Oh I am really not liking talking with you vj.

I did not know it would not do both. I am planning on a dedicated dish for 40.5 (C Band) and the tps are split R & L all the way down. Guess I will have to buy a second one and figure out some kind of mount for it.

I actually do appreciate the knowledge. You just saved me mountains of diagnostic time. Do you have a site where there is actual info on this beast?

Reinhold · #13 (**permalink**) 07-13-2006, 11:32 AM

Thanks again for all the help.
I do have a motorized set up (HH120) so I start with 0 skew.It seems that "0" point is not too clear.
Would you believe I down loaded 4 C Band sats using the QPH031 LNBF?
I get GOL tv on 111w,97W is olmost a carben copy of Ku,so is 123W C.
I also get one station on 129 and 131.
Thanks again for all the help.When it cools off a bit I'll start over and let you know how a make out.

can you take a picture and post how that plate fits inside?

Thnx

It is self explanatory when you take the cover off. I did not see any marks indicating which pair of slots was which but honestly wasn't looking either. They are just slight rises in the housing that create a slot for the plate to fit into. I seated my plate as far in as it would go without excessive force.

Reinhold · #16 (**permalink**) 07-13-2006, 02:05 PM

Can you tell me which way the plate should be for liniar;vertical or horizontal?
Reinhold.

PSB over on satelliteguys had pictures up. I'll see if I can dig up the link to his post.

Sadoun is a sponsor over there so I'm sure it won't be a problem posting to another forum

Second picture from the left show how it looks inside. You will see ridges on the insede where the plate fits in. You can put it in either horizontally or vertically and that determines if you get L or R (at least that was case in my test on 40.5)
