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

Re. raising 23.5, do you actually have that in a holder or without because I cant see how to raise it if it is in a holder?

I also tried your trick with a sliver of a piece of plastic in the arm.

hi, I actually get rid my motor after few years, its just brilliant to get all the sats from 4.8e to 42e, but unfortunately just couldn't wait to till motor tune to sat. I like zap zap brustic quick. so because of that I only got to use 4 sats for now. I am thinking to get second dish in future for more sats , for now, 7E,13e.19e.28.2e will do me

Yes its the holder, take a standard Triax LNB holder, cut it so the LNB collar is separate from the rail mount.
Then you build up the additional height you need/want with epoxy resin and reattach the collar.

Gotcha, thanks

lads I don't know if its against rules or anything but I do have plenty 3 way lnb holders for sale. if anybody want I will post it nationwide. only 8 euros including post I am adding the image

Here, €15, free delivery. the catch is wait forever and it may arrive one day because its from China.

Any day soon mine should arrive.

Hi STB - did you get this multbracket through yet?

Nope. Any day now I'll get a surprise..... Hong Kong post, its free, but unpredicatable.

For €15, I'm not expecting much. I'll post pics and results and soon as I get it.

Cheers I'd be interested in knowing how sturdy it would be in a windy environment.

excollier · 14-08-2013 08:47PM

I've fitted a few of them in Donegal and they are pretty good.

Good to hear - what are the clamps like - any chance of them loosening over time and loosing alignment?

BTW: where did you get yours from?

excollier · 14-08-2013 09:15PM

No, they wont loosen. I got them from ebay, but the supplier stopped stocking them - Vortech Trading i think

funkey_monkey · 14-08-2013 09:51PM

Did you need any bracing on the feedarm of the dish?

excollier · 15-08-2013 07:48AM

No, none at all, and I used twin lnbs on two of them.

Does anyone on here know about these multi-brackets?

I found them on this site (http://forum.zonehd.net/viewtopic.php?id=2956). I think the reason there is an X through it is because the image above it has them centered differently and also at different heights.

Excollier - how do you centre your dishes that you set up using the multibracket and what size of dishes do you use? I take it these are saorsat/freesat installations you are installing? Any chance of a pic of some of your setups?

I take it that you don't centre on one satellite so as to maintain some type of counterbalance on each of the LNB's and using the larger dish gives you sufficient strength on the Saorsat to allow you to do this?

excollier · 18-08-2013 11:18AM

Here is my own dish - a Triax TD88 with lnbs (from r-l) 4.8e, 13e, 16e, 19.2e, 23.5e and 28.2e(quad).
Also a 1.2m dish (with one of the brackets you mentioned above) with (r-l) 13e, 16e and 28.2e from a couple of years ago (when 16e was on reduced power.) It will be realigned to 9e next week for saorsat and 13e re-set and 28,2e removed to another dish nearby.
Alignment depends entirely on the group of satellites required.

. . . I think the reason there is an X through it is because the image above it has them centered differently and also at different heights.

The picture with the X through it is given there as an example of what not to use.

It would only work if the dish is aligned due south (highest point in the arc), or close to it. Any other alignment & you'd have to skew the whole dish to get the tilt on the bar, or modify the bar, or . . . you get the idea.

Tell us which Sats you want to get and then we can tell you which one to center on.

Hello guys, currently using a 80cm motorised in Dublin West but now looking towards getting an installer for a fixed dish using my other Triax 80cm dish. I am interested in getting 28, 23, 19 and 13. So do you think that it will work if I get Triax 4 LNB holder. Would I get maximum signals for all 4 sats using the 80cm dish?
Thanks

excollier · 18-09-2013 10:48AM

If it's a TD88, then those sats will be a doddle, and strong too. I have (had) the same in Donegal with no reception problems whatever the weather. See post #106 above.

sammyano · 18-09-2013 11:28AM

Thanks excollier, is the first pic on post#106 with the td88, for my mentioned sats, which will be the prime focus? I will now start looking for an installer to do the removal of motor and install the fixed dish

excollier · 18-09-2013 11:38AM

Yeah, the first pic is the TD88. In that picture I was centered on 16e, but for your setup you will have to get 19.2e as close as you can to centre, which is how mine is now (down to 13, 19.2 and 28.2).
Having said that if you centre on 16e with a normal lnb holder and then swap out for the Multiblock holder, it wil perform very well.

sammyano · 18-09-2013 11:50AM

Ok thanks a lot. Will have to explain to the installer so he can get the best signal as possible. Could have tried this on my own if it didn't require a ladder :-)

you might find it would be hard to get standard size lnbs to fit with correct spacing for 19 and 23 on an 80cm. You could use a slim size lnb to fit. Personally I would suggest a t88 or bigger.

sammyano · 18-09-2013 04:15PM

Cheers snaps, excollier has recommended the td88 which am going to order as to get maximum signal for all 4 sats

Also turn the bracket upside down and drill a new hole in it

excollier · 18-09-2013 04:26PM

No need to drill a new hole, just flip the bar.

The reason to drill a new hole is to re-centre the bar for an asymetric fitting - i.e. longer on one side to get a particular desired spread such as 9e KA Sat to 28.2e Astra 2 where 9e KA needs to be closer to the focus than 9e Ku would be.

What do you mean by just flip the bar? Thought all that is required is to point to 19e and the rest 3 sats will fall into place. Please explain more
Thanks

excollier · 18-09-2013 05:26PM

Just flip the bar/lnb rail end over end so that the mount hole is on the bottom instead of the top, give more incline to the rail so that works properly.
