At the moment I have a zone 1 satellite for Freesat, so I can fit a new satellite for Saorsat.
The Satellites are 22,500 miles above the equator.
A perforated Sky dish is no good for Ka.
Zone 1 is too small for Ireland, except maybe Waterford.
Satellite Internet is not a replacement for UPC, phone line Broadband or Metro. It has minimum latency of about 790ms. It's instead of unreliable 3G Mobile, VSAT (satellite two way) is only when real Broadband is not available. It uses a special dish/feed arrangement. Not a Triax dish and multifeed bar.
If you Don't have Tooway Internet, just satellite TV:
Sky/Freesat - - - Astra 19 -- Hotbird 13 - 9E
All are Ku Quattro. The 9E needs swapped for a Ka-LNBF. A Ka-LNBF is smaller internally but can be in standard mount. (Ka is approx 1/2" waveguide instead of approx 3/4" waveguide of Ku)
The 90/95cm Dish is aligned on 16E and Triax Multifeed bar is re-drilled about 1/3 distance to allow 28E further out.
The LNBs feed a EMP-Centauri 16+1 in 16 out multiswitch. Ka will only need one feed to one Multiswitch input as all signals are same band and polarisation. Two of the remaining inputs of those four could be L & R or H &V of C-Band.
No, the bush is not in the way, nor these trees (yet)
(The motorised dish is 110cm Triax using Motek SG2100, many years ago from Tony, www.satellite.ie)
Ka-Sat will primarily provide a two-way broadband service over Europe with an appropriate dish/LNB and satellite modem without a phone line.
Eircom are offering such a service (but its not cheap) - http://www.eircom.ie/cgi-bin/bvsm/bveircom/bladerunner/showContent.jsp?BV_SessionID=@@@@0119252257.1289171185@@@@&BV_EngineID=cccgadelmdmmiglcefeceiedffndffg.0&cid=BroadbandSatelliteRes&site=Res&chanId=-536889573

A satellite broadband provider could also bundle the Saorsat service as part of a satellite broadband package.
This from Conor Hayes last July
However while so-called Satellite "Broadband" is much better than so-called Mobile "Broadband" on reliability, jitter, packet loss, always on, speed and controlled contention if a decent package, neither are Broadband (Satellite Latency too high for games/real time and awkward for VOIP/Skype), especially not Mobile. Mobile has the value of being Mobile.
Different kinds of Internet Access: http://www.techtir.ie/forums/internet-faq
(Imagine WiMax is almost unique being really a Mobile system, but disadvantaged by wrong band for Mobile and no National Licence, so some situations worse than 3G mobile and others better).
Why even 21Mbps Mobile can be worse than 1Mbps DSL (phone line): http://www.techtir.ie/comms/mobile-vs-fixed
Mobile is best (only solution) when you need Internet on the go.
Satellite (VSAT) is best when there is no other broadband available. A better subsitute than Mobile and very like Broadband if you don't need VOIP/Skype or Gaming/Poker or eBay sniping.
Ka-Sat is primarily designed for European, Middle East and North Africa Interent Use, with 1000x capacity of earlier VSAT systems. Largest capacity ever. It just happens to be launching at the "right time" for Irish Digital Television with a few things to make it cheapest ever platform for Irish FTA satellite TV.
- About x10 to x20 inherently lower cost per Mbps of bandwidth (Price will not be so low
- Irish dedicated spot, 80+ spots with polarisation/band reuse further limits coverage (solves rights issues, makes it cheap)
- No Ku, so no demand for existing @9E TV platform makes it cheaper
- A spot is all one polarity & Band making single LNB output distribution possible.
- Prices aimed at competing with cheaper European Broadband, so TV carriage cheap.
- Uses DVB-S2, so less MHz needed per Mbps of data
- "Virtual Transponders", so can "create" two transponders with copy of terrestrial Mux MPEG-TS, allows for cheap DTT site backup and Community DTT, hotel and Apartment feeds converting via ASI from DVB-S2 to DVB-T with inexpensive off the shelf gear.
- Allows very small boxed "dish" that doesn't look like a dish, for existing Sky or Freesat users, beating the "one dish rule"
- Will actually work to edge of North East N.I., but essentially not in mainland UK at all (once French Spot ar Channel is active, before it is, large dish on UK West coast will work.)
If it's successful, a similar opportunity may not exist for another 4 to 5 years.
ok still a bit confused with the ka and ku etc having read all the posts...especially the disqeq switch thing and the point about the humax box being able to use it..will i still need someone to put another dish up or extra lnb on the sky dish to get saorsat? anychance of an FAQ thing for people like me who have some knowledge but are not familiar with the ins and outs?
Already extensively discussed.
A Sky dish can't even be used for a 2nd Ku LNB sensibly and can't really ever be used for Ka-Band. Just like many C-band dishes are not suitable for Ku-Band.
Actually we were the biggest manufacturers of bananas.
Most shameful thing from an Irish perspective about Diego is that Eircom used to have a Band 13 solely for there. Which makes no sense since the US military has their own comms and everyone else had been ejected from the island, The code was used for extortionate scam calls of which eircom got a very nice slice.
If a satellite broadband service provider could bundle the Saorsat service as part of a satellite broadband package it would be good.
I have no telephone line as Eircom would have to plant a number of new poles to reach my house, mobile broadband is slow in my location
Saorsat/broadband could be a reasonably priced solution
what does any of this have to do with the thread topic?
Surely that's Eircom's problem, not yours. They are the universal carrier, the extra money it would cost them to get you on the network is more than offset by the the fact that they can charge the same amount to people who live next to the exchange and it costs very little to hook up.
Does anybody here have any idea about Ka-Sat LNBs? I wonder would a DirecTV Ka-Sat LNB from the United States work or are they on a propriety system? I have a 1 metre motorised dish and can pick up 9° East no problem on the KU Band. I have relatives that might be coming from the US for Christmas and I could get them to bring it (if it would work) saving me both shipping and VAT costs, as internal US shipping is less than $10. I'd like to begin receiving any KA tests or trials from day one with the plan to buy the Saorsat dish and receiver box later on whenever it hits the highstreet.
No, DirecTV uses circular polarisations. 100% not suitable.
You can use an LNB off a Tooway (US Wildblue, Tooway in Europe). It needs a little horn. I'll be publicising a solution before the time. Nothing to receive till April anyway.
End December Launch
Clarke Belt positioning ( Jan)
System testing (Feb/March)
RTE don't get to put signals till the satellite is operational.
