Multi LNB set up.....

    Saw iba's photos and pm'ed him, he suggests I ask question here to help others.

    Hi
    I plan to set up a system the same as yours, 28, 26, 19.2 and 13E and was wondering how 26e works for you?
    Not sure where you are situated, but I am in Shankill south County Dublin.
    I will be using a Triax 1.1m dish but was told that the Triax LNB holder was difficult to set up as you cannot set the prime lnb over the centre.
    You seem to have overcome this and I like the look of your LNB set up and was wondering if you could give me approx distances between each LNB as it would be a great starting point, and how did you decide how much to lower the outer LNB's and also how much to the side did you drill new mounting hole?

    Thanks in advance for any info.

    Cheers

    Tony.

    You can aim the lnbs 'freehand' at the dish to find the best signal & use this info to position your bar & the lnbs on it.

    This of course assumes that you will have a display of signal quality within sight of the dish (I wouldn't even start without such).

    OP, just concentrate on 26 east to start with, with a single lnb and see how that works out over the course of a few days of day/night viewing & hopefully differing weather conditions.

    The stronger sats should be relatively easy after that.

    Hi Tony,

    Ive actually changed the set-up somehwat since I posted those photos and will try and post a new photo tonite but to try and hep you/answer ur questions in teh meantime:

    1. Im in Dublin 15
    2. Yes you are correct, the Triax LNB Holder has not been made to have a LNB in the middle but it can easily be modified. What I did first is to turn the bar upside down and then I drilled a hole through the bar about 5cm from the centre to give me a new centre. I then drilled another hole through one of the LNB Holders and the bar to enable me to be able to use it in the center. I attached this LNB Holder to thre bar with a bolt.
    3. The next step is to home in on Badr 26 - it can be a bit tricky to pick up thsi sat but with prerverence it can be done. Then Astra 28 i just to the side of Badr and is easily picked up. Hotbird 13 is right at the end of the bar and can also be easily enough picked up And then inbetween 26 and 13 (about half way) u will be able to get 19 (but there is nthing much on it).
    4. The tilt of the bari at it fullest - I mean Astra 28 is at the highest the bar will go and hotbird 13 is at the lowest.

    Im afraid its hard to explain some of this in writing but after u connect the new LNB holder to ur new centre u will understand/see how the tilt works.

    I hoep this helps you a bit and Ill try and post another photo or 2 tonite which may help more.

    Regards

    Iba

    Tony,

    BTW I forgot to mention that the signal for 26 comes in perfect, crytsal clear.

    How do you think one would go about deciding these things?

    Move the lnbs around until you find the best signal, that's how, unless you have some mathematical formula based on the dish's focal length or something.

    All you're trying to do is pick up signal that your dish reflects from a satellite further east or west than prime focus & lower or higher in the sky due to the Earth's curvature; that's really all there is to it.

    On the MBC beam? That's what the OP wants iirc.

    Sorry Peter,

    I dont understand what iirc means.

    I call the sat on 26, Badr, I think previously/and some others call it Arabsat - but yes MBC comes through on this sat, MBC Action, MBC2, MBC 4, MBC Persian, MBC Max etc etc - Dubai 1 is also another very good station that comes through here - shows lots of movies.

    Regards

    Iba


  • Registered Users, Registered Users 2 Posts: 233 ✭✭t c


    Thanks for all that Iba, explains a lot.
    Good to know that Badr is worth getting if there is movies etc. on it.

    If there is not much on 19E, would there be any better satellite between 13 and 26?

    Thanks again,

    Tony.

    Didn't you know about MBC etc. already?

    The fact that iba is getting MBC is a good sign, given that they're relatively close to your location.
    If there is not much on 19E, would there be any better satellite between 13 and 26?
    I would say no (take a look at the listings sites & see for yourself).

    Hi Tony,

    Yes I recommend Badr - MBC2 shows movies all day long and so does Dubai 1 most o the time. MBC Action shows a lot o TV series.

    U could go 4 16 degrees instead o 19 but not too much there either.

    Heres some new pics 4 u - might help. As u will c in one o the pics, ive turned the LNB holder on its side to bolt it to the rail.

    Any more questions, please just ask.

    Regards

    Iba

    Would you get 16E on an offset?


  • Registered Users, Registered Users 2 Posts: 233 ✭✭t c


    Cheers Iba.

    As they say "a picture tells a thousand words", which is true in this case.

    I presume the dish is a 1.1m?

    Not having seen a Triax LNB holder, the bolt you use, does it go right through the bar and sit on the LNB bracket (hence causing the tilt), or just through to the second groove?

    It looks as though this is the way I will go, though there is a multi LNB holder in Sat-World that may suit as it seems very flexible in its adjustments.

    Will keep people informed when I get around to doing it.

    Thanks again for all the help.

    Tony.

    Peter,

    Not 100% sure - when i tried a 4ew weeks ago i couldnt get it but i understand that a new sat launched at 16 last week - i think it might be called eutelsat - i read about it on another thread by a post 4rom a guy called Zardoz - but I have not tried mysel4

    Regards

    Just a quickie observation,

    I am surprised that you have such a big space between 26 and 28 LNB's, as I have read that toy need to use slime-line LNB's, or even shave the side of standard ones. Obviously untrue.......

    Tony,

    Yes the dish is a Triax 1.1

    Yes, I put the bolt right through the bar and yes that set the tilt i could use. Ur idea o4 just putting the bolt through to the second grove sounds like a good idea as it will give more room 4 movement.

    Would love 2 c ur pics when u get around to doing it.

    Regards

    Tony,

    I just used the LNBs that I had at my disposal and they worked so i didnt need to get any extra slim ones.

    BTW the LNB im using to get Astra 28 also picks up Eurobird on 30.

    Here is 13, 16, 19, 28, ( 23 also possible and 9 east )


  • Registered Users, Registered Users 2 Posts: 23,818 ✭✭✭✭mickdw


    Very interesting stuff here. Im looking to set up a dish to receive sky(have a contract) and also german RTL which I believe is on 19.
    Will an 80cm dish work for this and if so, which is the hardest to pick up. Should I centre dish on hardest one or should I centre it between both sats.

    I'm in Monaghan & have 28E & 19E on a zone 2 Sky minidish.

    The dish is directed at 28E & the 19E signal only seems marginally worse off; it will disappear in really heavy rain but 28 at this stage will be on the verge of going too (I'd really need a bigger dish for either).

    I would think an 80cm in Wicklow would be fine with either sat. as prime focus or a compromise between the two.

    You only turn the bar over to move the original fixing hole to the bottom, thus raising it in the dish-arm bracket which allows more tilt.

    If you're boring a new hole, you can put it wherever you want.

    Where did I get Wicklow from? :)

    I would think it would be alright in Mayo anyway, but a bit of local knowledge would be the thing to get.
