Who can help me with this LNB

**icees** · 27-08-14, 09:07 PM

Hi,

I need a twin LNB for the OPtus C1/D3 sat. LO: 10.7 and flens C120. Who can help me where I can buy this LNB????!! Thanks.
Much appreciated,

Marc from ICEES (the Netherlands)

It's a universal but it does have C120 flange.. Will cover C1 + D3 if you have 22khz band switching enabled

do u have a pic? where can I buy this LNB?

**icees** · 27-08-14, 10:12 PM

sorry found it..

Marc,

You cannot receive any of the Optus satellites in the Netherlands, just as those of us in Australia cannot receive satellites that only have footprints in the northern hemisphere.

So if you intend purchasing the equipment solely to attempt to receive the Optus sats, you would be wasting your money.

Sorry MTV for my double post. The LNB is for our project "Tom Prosser" in Singapore. It is really hard to find the LNB with these qualifications....

**mtv** · 28-08-14, 02:48 AM

You won't receive C1/D3 in Singapore either.

The beams are tightly focused on Australia/New Zealand

What exactly are you hoping to receive?

**icees** · 28-08-14, 07:07 PM

Sorry,the drilling platform will be stationed in Australia (build in Singapore)..

This is a clear example of not giving enough info (or too much info-Netherlands/Singapore) in the original question & wasting peoples time.

Thanks Tinny for your help

Well it's better to be clear of your intention when asking for help or people will stop helping.

Which leads to the next question, already asked & unanswered.

Most of the channels (Foxtel & VAST) are encrypted so you will need permission or a subscription to view them.

EDIT: BTW as far as I know oil platforms & other remote work areas are entitled to receive VAST. You can check & apply at

Got this task from my boss. Need to find a twin LNB: LO 10.7 with a C120. Don 't know what they need to receive at the platform..

Thanks again!

All the Best,

Marc

Marc,

I concur with Tiny.

The information you provided (or more to the point, the lack of it) was misleading.

There is a lot more you need to take into consideration than just a twin LNB

Yes, you will be able to receive Foxtel/VAST in Australia.

Apart from the LNB (and suitable decoders) dish size is a major consideration.

You have not mentioned if the intended dish is to be prime focus or offset, or it's size, as you must use the matching type of LNB for the design of the dish.

What location (distance from shore) and off which coast will the platform be located?

This is simple question of where to source a particular type of LNB. I don't see any other question's maybe we should stop journalising.

And one which was answered.

You have added to the 'journalising' with your post.

If you don't wish to add anything of benefit to the OP, then you didn't need to post at all.

As was discovered, the intended use of the LNB was unclear at the beginning, however, with 'journalising' as you put it, its intended use is now clearer.

Rather than just leave it at that, some of us are actually trying to help the OP ensure what he sources/purchases, will perform the job for which it is intended.

Still need this TWIN LNB. Local Oscillator freguency: 10.7 GHz and C120.

geosatman provided a link in post #2 and you said you'd found it in post #4.

The LNB in that link, as mentioned, is a universal type, not a single LO.

It will operate to cover the range that a 10.7GHz LO will cover providing the decoder can use the required 22khz switching tone.

C120 flanges are typically used on prime focus LNB's in conjunction with a C120 type feedhorn on a prime focus dish.

The LNB in that link is designed for that purpose.

I am not aware of any dual output single LO 10.7GHz LNB's with a C120 flange, as they are typically a commercial product with a single polarity.

If you absolutely must have both polarities (Eg: H & V / two outputs) you can use two single polarity 10.7GHz LO LNB's such as those listed in conjunction with a Ku-Band and a Ku-Band Dual Polarity .

All of these components use the C120 flange and are intended for use on a prime focus dish.

Marc,

Could be worth talking to these people:

They have an extensive range of more exotic gear - not cheap though.
Although I dare say that if this is for the offshore environment, price may not be the sort of consideration that it is for us amateurs

I'm guessing that the project is to set up VAST on the rig for its stay in Australian waters.
I checked my Satking VAST receiver, and it can be setup for a Universal LNB (L.O. 9750/10600) as shown in Geosatmans post #2.
I assume that the other two brands of VAST receiver have this facility, as they are all built to the same basic VAST specification.
If so, then the use of a Universal LNB, as opposed to a 10.7, should not be a problem. Most of the C120 LNBs in this band appear to be of the Universal type.

Good luck with the LNB....and the drilling

**mtv** · 29-08-14, 10:23 AM

Yes, VAST receivers can be used with universal LNB's, but not Foxtel receivers.

This is why I asked Marc what they wished to receive. (and at that stage, he hadn't said it was for use in Australia)

He hasn't provided answers to many questions asked, trying to help him.

It sounds like he has no idea about the requirements, only that his boss gave him the task to. 'find a twin LNB: LO 10.7 with a C120.'

Because there are many variations with LNB's 'Twin' can often mean Hi and Lo outputs, unlike 'dual' output, which is typical of an offset 10.7 LO LNB used for Foxtel, etc.

These (as you would know) provide two fully-independent dual-polarity LNB's in one enclosure, to be used on an offset dish.

The C120 flange which is typically used with a separate feedhorn, is designed for a prime focus dish.

A VAST decoder only requires a single LNB, which makes me wonder if the intended use for the 'twin' is for Foxtel.

If that is the case, then a universal LO LNB cannot be used.

Perhaps the 'twin/dual' output is indeed intended for VAST in conjunction with a multiswitch for distribution to multiple decoders.

If Marc doesn't understand exactly what he's looking for, it's probably a bit unfair of his boss expecting him to choose the correct LNB for the intended purpose.

Perhaps his boss doesn't even know (I've known several bosses who don't know much about a lot of things related to their business)

Realistically, if the company is not 100% certain, the job should be left to an experienced installer who can determine what is required to provide the result they desire.

Between us on this forum, we've provided Marc with several options to source the LNB.
