    The advise I received was to turn the bar upside down. I took that advice and it worked, what more can i say.

    You're missing out on a chance to learn by just blindly following instructions; you'll get more pleasure from a task when you know why you carried out a modification. :)

    is this thread still alive iba, i am sure there is another one now. i will show you an image on how to secure the lnb arm but if you had instructions with the triax holder its got a little picture.

    i saw it but had to rush out, i did a quick reply but don't know if it went. here are 2 images, if not clear enough let me know. I am putting them on here in case others may need them but lately I am beginning to think why bother?

    Sorry GB.

    Not sure what pics mean. My Triax came with that bolt and nut and already drilled, is there something missing?

    I thought you meant to strengthen whole arm as it does not seem the strongest, just aluminium.

    I hope to get time next week to start mounting new dish, just not sure of the best way to mount a 1.1 or, in my case with electric cables, where.

    tc, look closely at dish, the way i read it is use 2 bolts, can you see the indent on the image. maybe the new triax have changed the way lnb arm is held in place. i will have a look at a few. the idea is the arm will sag a little under the weight. Or if you can post a pic of your dish showing where lnb meets dish. If you cant do it you cant. There is another method that I read about stabilising bracket somewhere and may dig it out.

    My triax is 12 years old!! told you I was getting too old for this malarkey and after some of the comments by a few on here maybe you can understand why!! What was that saying at work " Dont let the ........ grind you down""

    Helle guys how is going? well I have 1 metre of dish, I recently rid of the motor, I didn't want to wait and motor was bit noisy , so because of that I decide to setup multifeed lnb setup. I wish to get 7e,13e,19e,28e option 42E, so what is the best way for me to set this, what should be my zero point? which satellite?
    note :
    attaching the picture of my setup, at the moment dish set it to hotbird

    Thank you

    I actually have one of those brackets you are using on order for messing with. I currently use a Triax TD88 with the Triax Multibracket, but I had to redrill that bracket so that the majority of the bracket was on one side in order to allow the rest of the bracket for the spacing to 28 with the prime focus on the lowest E satellite (4.8E), so I get 28 to 4.8E.

    On a bigger dish the spacing becomes wider.

    28E to 7E should be okay. Can that bracket slide to the left (looking on) or is it set ? You need to have prime focus at 7E and then everything else to the left of it. Otherwise your 7E will suffer as it will be the weakest.

    Example this is [url=https://us.v-cdn.net/6034073/uploads/attachments/167996/242412.jpg[/url].

    STB looking at your pic and working left to right can you tell me what sats you are getting?

    That picture above was (left to right) 13, 19.2, 23.5, 28.2 and 39E.

    Other variations....

    My current setup is (left to right) 4.8E 7E 13E 23E and 28E, I havent got a picture of that at the moment but the arm is pointing at apx 8E with the bracket redrilled so that only 2 lnbs are on the left and the rest on the right to maximise space.

    hello thnx for the Quick answer, yeah that white lnb on the middle is prime focus to 13e at the moment, like I said before, I am currently using 1 metre dish, do I have to upgrade the size for better signal and more sats? I actually can get longer tube stick to extend area and number of lbs, I do see sometime online people has like 6-11 lnbs on the single dish , for this position what position my dish Should be on? like to get for now 7e,13e,19e,28e options also wanted to get 23e,42e

    hi,
    Yeah finally solved today, got 7E,13E,19E,28.2E so far with 1.1 dish , so far sats are grand except 28.2E for exsample I get only %56 signal rate on sky news. just couldn't get higher signal what so ever ,I hope wont couse any problems when is raining .
    cheers

    You don't need a bigger dish. I get those satellites on a smaller dish than a 1m (88cm Triax).

    With that adjustable bracket you are using your biggest issue is the bracket being long enough to cover 7E to 28.2E. If you are only getting 56% on Sky News it is a sign that you are not fully tweaked. Even with the satellite dish pointing at 7E with the furthest offset at 28.2 you should have no problem getting 60-70%+. 56% on weak TPs like Sky News which will become unwatchable when the bad weather kicks in.

    If your dish elevation is set around 29 (use dishpointer.com to get exact elevation for 7E for your area) on the side of the dish, then to maximise 28E reception you will need to move the 28E LNB holder higher vertically and skew the lnb (the 7E LNB holder will be lowest vertically). That is the good thing about those brackets. The bad thing is the bar on the bottom may not be long enough.

    Hi again, yeah I was thinking that I don't need bigger dish,but I haven't got a chance to see whole at sats yet, if start giving problems at bad weather, then I will do what u said, here the picture of it. let me know if everything looks fine to you. cheers

    EEmm, not 100% sure about that setup. Is it secure (I.e does the lnb holders feel secure), Im worried about the wind moving those LNB's. Also usually in most Multi LNB brackets you have a curve in the bracket arm, Its not straight. This usually compensates the arc.

    If you look at STB's post and picture you will see what i mean.

    It would if the vertical lnb holders were twistable. They are not fixed, the do twist around allowing tweaking on each lnb effectively.

    Yes it looks good. You can see the arc from the amount of the vertical poles that are left at the bottom. The only thing is that you are running out of vertical pole on 28.2 ie upwards.

    To tune it perfectly higher the elevation on the dish and sort 7E first (whilst getting the 7E at its lowest on the main holder attached to the arm). This will allow you to have more tweaking on 28E etc which require the higher positions for lower elevation.

    As I say I ordered one to play with as they seem to offer more tweaking possibilities for maximising reception. The Triax bracket after modding still doesnt offer enough elevation on the bracket between 28 and 7E.

    Yes, I see now how each could be moved closer to or further from the dish.

    I use the Triax for 4.8e - 28.2e on a TD88, and have no reception problems with 28.2e, elevation is ok.

    Same here, no elevation issues with 28.2e on a 12.5 degree offset on a modded Triax bar.
    However I do find that 23.5e and 9e seem to need to be higher than the triax bar generally allows.
    If I peak signal on 4.8e and 28.2e, it should follow that I am on arc with the bar.
    However I still need to add @6-8mm height to the individual LNB positions for 9e and 23.5e to get those birds peaked.

    I like the LNB holder STB linked!
    I was looking for something similar a couple of years ago and bought a similar setup with a curved bar and height adjustable holders but that one looks a lot more solid than my previous one.
    It was brilliant initially, great for individual tweaking but after a couple of typical Irish weather days I found it needed to be adjusted a lot(after every blow really)
    Unlike the triax bar which is rock solid, only time that needs going at is when I'm bored ;)

    Same setup. 4.8 to 28, prime at 7/8.

    Its probably where I re-drilled it on the bar. I have the prime focus at 7/8E so I could get max strength on 7 (as thats where the majority of the feeds are these days) so the tilt is not enough for the borderline TPs like PickTv etc on 28E. Even tried your trick with a thin sheet of metal under the arm.

    I'll wait for the new toy bracket to arrive. If its crap I'll go back to tweaking the Triax when I buy a new drill, which went on me today. What I really want is a motor !

    Anyone noticed that those feeds with a S/R around 14400 are difficult to receive on a VU ?

    There's the difference, I have 16e at prime, so 28.2 is closer than yours with 7e at focus.

    hi, I didn't set the dish my self, see I don't have decent sat meter, that the problem. I call one of the guy who has pro meter but not permanent installer . so cheap and cheer full so they say . I will try on openbox to night actually see how is all the sats, and I am well taking your advise you are very helpful. I thank you for that, and I read other comments about these bracket, my own opinion is, I reckon those ln brackets are better than triax ones, I found so handful to use. adjusts very simple and cleverly work on the lnb holders , I even have 3 way lnb holders many of them in stock(. didn't want to use it, because I think this Chinese one is deadly job.
