Re: Ka band

This might be useful to the forum.
I found an interesting article on Wikipedia
Testing started in May 2011 on KA-SAT 9E, 20.185 GHz DVB-S2 SR25000 FEC 1/2 with pre-recorded material.
Parameters are:
KA-SAT @ 9E 20.185 GHz, Left Circular Polarisation, DVB-S2 QPSK, SR 25000 with 1/2 FEC (allows about 25Mbit/s data, about the same as the Terrestrial Mux), Irish Spot (there are 82 spots on KA-SAT)
RTÉ submitted a revised DTT plan including the FTA satellite option to the Department of Communications in mid June 2010 for approval.[3] RTÉ publicly announced at an Oireachtas Joint Committee on Communications discussion in mid July 2010 that a free-to-air satellite service, called Saorsat, would be offered to complement the terrestrial DTT service.
The satellite option is a narrow-band satellite operating in the Ka band as opposed to the normal DTH Ku band (which Sky and Freesat use), with a spot beam being dedicated exclusively to Ireland which will also provide coverage throughout Northern Ireland. The spot beam with frequency reuse means reception in Britain and continental Europe is not possible. RTÉ states that the chosen satellite option will cost approximately €1.5 million per year.
RTÉ said the combined offering was designed to be the most cost-effective solution for viewers and broadcasters; to offer for the first time 100% coverage of free-to-air public service television services in the Republic of Ireland; and to provide full national back-up coverage on satellite in the event of an emergency or catastrophic failure of the DTT system.
Approval for the revised National DTT plan and Saorsat satellite service was announced by the Minister for Communications at the end of July 2010.
Any DVB-S2 HD satellite receiver can in theory be used to receive Saorsat as the Ka band LNBF converts to a regular IF in the 950 MHz to 2100 MHz band. If the receiver does not have a setting for the Ka band LNBF Lo, then a "fake" frequency 10.765 vertical rather than the real 20.185 may be entered when using the Inverto LNB with local oscillator of 21.2
To receive Freesat/Sky or other services on the same set-box as Saorsat, a Dual or Multi-feed type dish or two dishes are needed with either one or more Diseqc switches or a Multi-switch. On a multi-switch the Saorsat LNB needs to be connected to vertical 0 kHz port only. The other 3 input ports are left unused.

Re: Ka band

Hello, lnb there but its price is expensive right now are around $ 1000

Re: Ka band

You could get one on ebay for under £30. I dont think anyone would be able to pay about $1000 for a Ka band LNB. Please do some search on the internet.

Re: Ka band

Hi Obiwon,

Unless you live in Ireland, or very west parts of the UK like Wales and Cornwall you will not be able to pick up this service.

Re: Ka band

It is supposed to be a cost effective solution from RTE to FTA service to cover 100% area of Ireland. I think UK FTA or Freesat is still a good deal. They have similar service in France a FTA freeview. When I go to France I take my DVB stick with me.

Re: Ka band

i read that Saorsat boxes like the Triax TSC114 HD are expected to cost around €180, with a dish and Ka-band LNB €35 each and it’s on Ka-Sat at 9°E, about 19 degrees to the West of the Astra 2 satellites.

Re: Ka band

That is still a lot expensive. You could buy a Freesat HD Box and the whole set for under £100. Most of the modern TVs have already got Freesat HD in them. All you need is a sky dish or any other dish would do.

Re: Ka band

Just an update. I was searching Ebay and you ca buy the whole kit including a Goldenmedia Wizard receiver for under £140 which is almost the same price for Freesat with a good quality receiver.

Re: Ka band

The Ka Band foortprint for these channels at 9° east covers all of the UK so should be easy to pick it up, But is it really worth it for 6 channels currently broadcasting which 2 of them RTE one and RTE TwoHD are already broadcasting on the Astra Satellite at 28.2° east

Re: Ka band

There are many spot beams on 9E and frequency re-use makes reception in most of the UK impossible.
