My various T90 setups with many LNBs - different solutions for it...

  • Guess what: my wife doesn't want to remember what is where and doesn't wanna wait for a dish to move, doesn't wanna think about moving the dish from one channel to the next, doesn't wanna think if something is being recorded, so she can't move to another satellite etc. etc. Hence, she deeply appreciates my T90... ahem... BEAST!!! :laugh1::rasta2bigsmoke0gf1::P


    I warmly recommend this system for all true hobbyists willing to fight for their right to put it up and keep it up! :P:rasta2bigsmoke0gf1::laugh1:


    So, we lived in Sweden, Luxembourg, Italy (2 places) and UK (2 places) and that required various solutions, in terms of how to set it up. Hope this helps, if you're thinking about it... Here we go...


    =========MY first T90 setup in Sweden============


    Pay attention if you have a flat roof and you can not drill into anything, plus there is no strong chimney!!!


    761d175d331.jpg


    This solution [with two "palettes"/wooden base used for transporting packed goods - is quite elegant. Just

    -nail it [strongly connect one with the other, maybe with screws, even] together, then

    -secure it additionally with some weight, if there is strong wind, where you live, other than

    -connect it, using a metal tape, running all around other constructions on the roof and palettes.


    I reckon one should also paint it with a water-proof sealant, against rotting, to protect it against the elements [rain and snow]. So, start doing that at least a day before you want to install your dish!

    Now, the details of what you will see on these images:


    -2 x wooden base to place it securely on, plus
    -some metal tape to secure it around some fixed objects on the roof, using screws going right through it, into the wood/brick/etc.

    -1 x Toroidal 90cm dish-13 x Smart Oxid Twin and

    -2 Smart Titanium Twin LNBs [2 cables going out of each LNB to 1 Twin tuner receiver or 2 single tuner recs] +

    -1 Quadro LNB [4 cables running from it, as I need an additional cable for my subscription, official receiver]-2 x Centauri 16in1 Switches [only 2 cables running from them to my flat - 1 for each Sat TV tuner]

    228ad62b.jpg


    Advantages:


    -instant switching from one satellite to another, no waiting

    -no noise to move from one to the other

    -wife happy, as she doesn't need to either remember what's where or wait...

    -neighbours happy as I am not waking them up as I surf the skies in the dead of the night, not to mention the wife...

    -possibilities of recording not only from 2 different transponders but from completely different satellites


    One could put 16 Quad or even Octo LNBs, of course... either for more receivers or even sharing with neighbours...

    I have the following 19 satellite positions, here is Scandiland, with 16 LNBs:


    16. 30° West

    15. 24.5° West

    14. 18° West

    13. 15° West

    12. 12.5° West

    11. 8°[I can not get +7° in Scandiland with my equipment but elsewhere it might be possible!] West

    10. 5°+4° West

    9. 1° West°

    8. 4°+5° East

    7. 7° East

    6. 9°+10° East

    5. 13° East

    4. 16° East

    3. 19.2° East

    2. 23.5° East

    1. 28.2°+28.5° East


    One has to add the transponders from one satellite position to another, manually but... it's well worth the effort, let me tell you... Cool to see it working!


    I have almost all transponders on most of the big, important satellite positions, except some weaker ones on 28.2°+28.5° East, 4° and 8° West.


    Some other TPs are missing on smaller satellite positions but I have loads and loads of channels, left, right and centre, so no probs...


    Here is how you calculate your position, your central position, then your elevation etc.


    One must be patient, to sort out all the angles right in all 3 dimensions...


    Here is the online calculator, wherever you might be:

    Just print your data and go... :)


    Quite a treat, this setup...:thumbup:

  • Btw, the guy who started importing this Korean marvel, is from Luxembourg (Sathifax) and they engineered their extended version of the usual T90, which caters for 45 degrees span.


    Their enhanced one caters for 60 degrees. Hence, the above additional "stretching system" was not needed, to go from 28E to 30W!

  • I'm lying... Up on the terrace I had a Gibertini 1.5m with a special LNB, to get 28E BBC etc. Barely...


    Have a look at that little feat, supported by a flimsy wall, with plates at the other end, since the screws had to go right through that wall... Uhh...

  • They did (but on the smaller dish only, not T90) - we strengthened them and now it's all cool...

  • Moved to London, new pics coming...


    One Q: anyone in/and around London with T90, please?


    1) Is your central satellite 16E?


    2) What is the signal like for HRT 1-4 on 16E, please?


    I get only 7.75 - 8 dB (38 - 40%) at the moment... hence the Q - shouldn't it be stronger?


    Cheers! :)

  • To answer my own question: after the necessary corrections HRT on 16E gets me between 49 - 52%, i.e. around 9.75 0 10.50 dB.


    But RTS on 1.9E gives me only 43% = 8.75 dB. We'll have to try to improve that...


    And the latest installation... :rasta2bigsmoke0gf1:

    • Official Post

    i know nothing about parabolic setups.........but surely you would center it on about 5east to get an even spread of lnb's each side of center ??


    This also may be no help what so ever:rasta2bigsmoke0gf: :-

    I get 97% snr on RTS HD @1.9east

    The FTA channel HRT 1HD @16east i get about 65%

    Figures are on the 80cm motorised dish, London area.



    :tinfoil:

  • Thanx for checking on your setup!


    Btw, super photo! :laugh1:


    It is different with multifocal dished with 2 reflectors...


    To me 16E is the most important, so I am starting at 39E and going to 7W (not using that one but the last one I use is 5W).


    That makes 16E the central satellite for me. But we'll fix the 1.9, thanx! :)

    I have - in that area - 10/9E, then 5E, 1.9E, followed by 0.8/1W etc.


    One puts 1.9E in the centre of 3 LNBs and then improvises with 5/4.8E and 0.8/1W around it:

  • Sorry, I forgot, it was down to 1 element at the back of the dish, which was too loose and when the wind came it lifted the main dish a bit and it got stuck in a wrong position....


    So, now HRT on 16E gives me 11.40 - 11.50 dB and RTS on 1.9E around 10dB... :)
