    It seems strange the ROI would use circular LNBs/Ka band for DTB broadcasts these days

    I always though it was old school technology or specialised stuff for outside broadasts

    Its been years since the nordic countries used it on Sirius satellite

    I mean ITV & BBC have a footprint of UK & ROI for their broadcasts but with right set up folk are watching these channels in Canary Islands!

    It would be more attractive to encourage viewers to switch to digital sat & be able to either use existing Sly box or dedicated FTA box similar to UK

    Otherwise means buying new stuff in a country where money is tight at present

    no way this ka spot beam will reach the canary islands not even a hope in most of the uk they use the ka spot beam to protect copy rights i have no idea why they need to go down this route 28e allready has all the irish channels on protected by nds card as for the circular polarity probably h v would have been ok but not sure with the sat being ka band

    dont think you can use a standard receiver to power the tooway lnb.
    i have installed a few of the tooway systems and tried to line them up using horizon meter. there was not enough voltage to power the lnb.
    had to use a inline bleeper meter with the feed from the modem

    RTE are using this method exactly because of the very tight spot beam.
    It means they can broadcast totally FTA and protect their rights issues, no overspill to the UK.
    They need to do it this way because roughly 5% of the population here cannot receive the newly implemented Saorview DTT broadcasts, so a FTA satellite broadcast is the simplest solution.
    To issue Sky equipment to all the affected people and a FTV card would prove very expensive, RTE are broke, as is the country.
    To use Ka-Sat will only cost around €1.5m per annum, way cheaper than FTV on Astra 2D, and way way cheaper than FTA on same, because of the UK wide footprint and the associated rights costs of broadcasting to a very much larger audience.
    Hope this explains the reasons why.

    A quick update on the Ka lnbs: the supplier I normally use will be speaking to importers later this week.
    He says the manufacturers need huge volume orders to justify production, so don't hold your breath.

    Wow, so you're receiving Irish Ka band in North Wales? Sounds like the spot beams are not as tight as originally thought....

    yes i agree with a tweak the quality is now 0n 50% but the signal is constant on 68% my meter is broken so i can't maxamise the signal but a smaller 1m dish should also work probably the signal should also be receivable in some parts of england with the right sized dish but there is some talk of the french beam causing problems only further tests will show how far the signal will reach i'm also interested if any others are able to receive this signal in england wales or scotland

    Satwyn, thanks for the quick reply, and pictures would be good for all us wanting to try this out. I was thinking of ordering the DirecTv SWM 3 LNB. This may be a problem to mount, will try to get more info.

    the swm 3 is not what you need either the hughes or tooway would be a better option these are known to work the tooway needs 24-30v to power so that's why i use the hughes also the tooway is an all in one rx tx type and can't be seperated so if you are interested in receiving the signal the hughes ka is your best option at this time i use mine with no feedhorn or polariser with signal at 70% quality 70% on a 1.2m in wales you would need to seal the front of the lnb from rain ect
