Just noticed that Australian Network are advising that their program will be shifting off Intelsat 5 to Intelsat 18 and that this will require a dish realignment and also a change to circular polarity.
Does anyone have information on this and what it will require to keep Australian Network. Also what about BBC is it shifting as well?

See http://australianetwork.com/tuning/satellite_pacific_DTH.pdf

I've read BBC is following suit to IS18, but it going HD and DVB-S2 as well, but I've yet to verify that as anything other than gossip.

Thanks I read that but its a little confusing apart from the fact that they state that we would need a 2.3 metre dish to receive the programme. I am ignoring that I think Australia does not especially want New Zealand picking up their content.
What I do want to know is that if the dish is realigned and the horn gets modified for circular polarity how will that affect all the other content on the same dish. At present I get all the freeview channels and also NHK BBC & Australian Network.

Ron, The other stuff viewable from NZ on I-18 is Ku-Band, so you won't get it with a c-band Right circular.

NHK you must be getting off D2 so no change. Or the other possibility if you are getting NHK, BBC and Australia Network off the one dish is that it is a large dish and you're getting it off I-8. I-8 was getting replaced with I-19, but I-19 has had some problems. I don't think Australia Network is exiting off I-8 at the same time it is exiting I-5.

So Intelsat's plan was launch to launch I-19 and move it to 166E to replace I-8, and I-8 was to be moved to 169E which is where I-5 is now. I-5 being decomissioned. I-18 is at 180E and will remain so. They're still testing I-19 after its solar array problems so those plans may be up in the air.

Many C band LNB's come with a circular polarisation 'disc' from memory. How does one use it?

Thanks that makes sense. I have three LNB's so guess I just have to get the Intelsat 5 LNB converted to circular and maybe the dish will need re-aligning. I understand that it is likely to be September before I-5 stops so I will wait until things settle down a little and then make the change.
Does anyone know for sure if TVNZ Pacific Services are on I-5 and if so what will happen to them. I-18 may not be suitable for some of those areas

The dish sizes might be wrong but some of us won't be picking up Australia Network with a 90cm dish anymore as the new signal is weaker.

I've read BBC is following suit to IS18, but it going HD and DVB-S2 as well, but I've yet to verify that as anything other than gossip.

BBC is already on Intelsat 18 but PowerVu encrypted. We may be able to get it from Intelsat 19 with a 2.1m or smaller dish.

Let's get the facts straight:

IS-8/19 has or will have the full mux for BBC Worldservice and ABC's AN for Asian viewers and needs a 2m dish for NZ.
IS-5/18 has of will have intelsat re-fed versions for Pacific viewers and will require a 2m for NZ when the sats move.

So based on the fact that IS-18 uses circular C-band for transmission to ships in the Pacific, you would be better off getting a bigger dish for IS-19 and use an existing offset scalar to get the one of the Optus birds on the same dish. However if you live in a urban area with very little room or low elevation, you are basically out of luck. Meaning C-band FTA satellite services are going back to the domain of BUDs.

If I was going to get a 2m+ dish, then I would point it at Optus C1/D3 in the expectation of being able to tune in to all the Ozzie channels broadcasting via VAST (I would get a VAST receiver via Ozzie Ebay).

What is a real pain is that our 1 metre dish is going to be pretty useless once the moves complete.
I cannot get a bigger dish as I doubt that it would see the horizon apart from the fact I am on a pretty small section. 1 metre is fine for the roof but not sure I could carry much bigger than that on roof.

The Intelsat website shows there will be a signal strength of 38.9 dBw for New Zealand from Intelsat 18 for C band,only a little less than from Intelsat 5 at present (around 40dBw )
Perhaps we should wait until the new service starts and maybe we wont need bigger dishes as suggested?

I think all will be interested in the attached link. Part 4 the most interest to this topic.

http://www.jayx.co.nz/

In reading the articles, its highly likely that we will be able to get a quality signal here in NZ. I am going to purchase a new dish regardless. Looking more so to a 1.2M off set if i can find one. My 90cm dish i am going to leave for Freeview and also Optus D2. ( More so for the V8 Super Car Feeds). We should know more next week , when IS-18 and Australia Network are up and running on that Bird if a 90cm is still Viable. I believe it is!. From what i hear we have till the end of September for the Australia Network on IS-5.

The real problem is that IS-18 is too far out to use an offset scalar and uses circular meaning you would be needing more room for a fixed dish. As uses a motorized dish would pointless as other C band birds use linear. And I'll put money down that only australia network is moving and the when IS-5 goes the uplink beam to IS-8 will be the same just that the Hawaiian mux will have no ABC service. Also IS-18 is not practical for the wild feeds that come off IS-5.

I heard you could get more off of C1 with a 1.2 m dish, is that true? As for a VAST receiver, couldn't you just set a box id on a softcam that matches a card?

This article discusses what is available from Optus C1;

http://www.jayx.co.nz/C1%20over%20spill.pdf

From reading the article I understood that a 1.2m dish would not give you a reliable and watchable service, but a 1.8 meter dish might be OK for the horizontal transponders. If you want to get the vertical transponders too then a 2.4 meter dish may be necessary - and it still depends upon whereabouts in NZ you are.

It still sounds like a better bet than getting a 2m+ dish for C band services off Intelsat 8 or 18 or 19. However, JX have published another article suggesting that we may be able to access I8 I18 and I19 with 90cm dishes. There may also be some Ku band content that we could access with standard dishes;
http://www.jayx.co.nz/

Thanks for the tip about softcam! (however, I just don't have the real estate on which to place a dish big enough to get VAST).

That's very ideal and premature speculation, I would still say that IS-8 will offer similar to what IS-5 offers. ie, not much change
