Using BSC621-2 C/Ku LNBF

[Reinhold]

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.

[vj9999]

And one more...

[Reinhold]

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?

[Reinhold]

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.

[Reinhold]

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.

[elgemcdlf]

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]

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

[elgemcdlf]

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]

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

[vj9999]

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

http://www.satelliteguys.us/showpost...0&postcount=28

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)

[pmb1010]

must have missed that post over there.

thnx

[Reinhold]

vj,thanks for your efforts.
It cooled off a bit last night and I was able to get up on the roof.I got some Ku station before the storm went thrue.I changed the baffle plate and that did it.Thanks again.
Reinhold.

[pmb1010]

Changed the baffle plate from what, to what?

Ill be going thru all this in a couple weeks.

[Reinhold]

The baffle plate can be installed two ways 90 degr apart.It is obvious when you look at the nubs inside the tube.
Reinhold.

[vj9999]

You shouldn't really be using dialectric plate on Ku (or C unleass you are looking at circular c-band sat). In all other cases it will most likely degrade your signal . I believe it was only intended for circular c-band sats.

[Reinhold]

Hi vj.
Haven't gone up on the roof yet,but I am looking for a cone shaped scalar ring like you are using.The one that came with it seems to be for installation on C-Band dish.The last time I had it installed I got some Ku-Band station.There seemed to be reduced signal though.I did not use any scalar ring.
The QPH031 LNBF works really good though,but that 4 way DiSEqC switch from sadoun seems to be not too reliable.Sometimes it works,other times it doesn't.
Reinhold.

[pmb1010]

Well, I picked up my 120cm dish from Sadoun's warehouse the other day.
Bryan is a nice guy. I ran into Mr. Sadoun (I think, he never really said who he was, he seemed more interested in my paying the "handling" pickup fee than finding out anything else... which was OK I guess, he runs the business)

I know it's a very compromise antenna on C band, but let me assure you guys - this will be a big stretch to get past the auspices of the wife on this one. If I wanted to put up a real C band dish, I might as well put it, with all the rest of the stuff I own into the trunk of the car, as I'd be heading for city mission for a place to stay...

She tolerates the big ham beams, sort of. And the few sticks (FM UHF/VHF antennas) on poles on almost every corner of the house.

She saw the 80cm dish go up, after I tried to see what the DISH network dish I trash picked and hooked up to my FTA Ultra to see what it would do (not much at all). The 18" was OK. But the 80cm dish was "look how big it is...". What'll she see this thing. Oh boy...

Now I got this pie tin to install. I hope it's not like trying to hold a garbage can outside a car window at 60mph... looks like it could trap LOTS of wind. I'll try to take some JPG's of the install and post them as it goes.

Anyway, I have the BSC type C/Ku LNB with the flat scalar ring.
Reinhold has me concerned, getting questionable results with the flat ring.

VJ, did you get anywhere with flat ring? I'm looking for a challenge, but not frustration.

Comments welcomed as to what to look for, results wise. I know whats strong Ku wise, but not C digital wise.

WHat can I expect?

[vj9999]

I haven't really tried too much with flat ring. I did before when I had ASC421 and it was possible toget results, but you will have to play with the correct focal distance setting for it (by moving the ring up and down the lnbf).

As far as signal strength, there are some transponders on C-band that I can get in with 60-80% quality. Most of the time you will be looking at around 35-40% and that can be enough unless it has inerference from adjecent satelits which will make the picture breakup or give you ni signal at all.

I haven't done much in a month so I can't tell you what sats will give you the best results. If youdo get anything to scan in, post the sat/frequency and I can compare the signal/quality I get on it.

Hi pmp1010

Thank you for your business. If you ran into me, sorry I didn't recognise you.

I hope anyone visiting us at the showroom from this board to please introduce youself to me if I am around. We like to take good care of all of our customers and specially the members of this forum.

[pmb1010]

Reinhold,

where did you end up with the flat scalar ring in relation to your LNB to get any signals on C band?
Got home today from a week of business training in Ohio, and put the 120cm dish together.

[Reinhold]

I haven't fooled with it for a while.Its been in th 90th every day and it gets pretty hot on the roof.I found somebody that had a Ku scalar ring.It is on the way and I will try again then.

Reinhold.

From whom? I'm also interested in this setup. Please let me know your success. Please contact me privately concerning where you got the ring.

Thanks, Mark.

[pmb1010]

This C/Ku LNB has a cap for the upper end. The cap has a ring of small holes.

If, by chance rain or condensation moisture were to get thru these holes into the LNB, where's it going to go? There's no weep holes in the lnb body.

Think it might be a good idea to seal this with silicone, and mount the cap with removable sealant to keep out water? All other LNB's I've ever seen are fully sealed...
