View Full Version : Dish position for Astra 28E & Hotbird 13E from one 80cm dish?

Hi

Me again!

I have purchased from WoS an 80cm technomate dish together with a Technomate Triax Multi 4 Way LNB Holder bracket. I am using two twin lnbs which will be eventually configured via diseq to two different satellite boxes.


I have locked it on Astra 28 and spaced out the lnb acros the bracket but although I can get Astra of course I can't pick up hotbird.
Before I set up the box with diseq I ran a cable from each lnb to ensure that I can a signal from both satellites. Of course 28.2E was ok but no signal from hotbird when I swtiched the cable to the other lnb.

Can someone please advise which dish position I should have the dish set at? set it at Astra or Hotbird or in between?

Perhaps I should invest in a signal meter I know! :)

thanks

No need for a signal meter if you have a smartphone or tablet...

Use a channel list with both SATs & gently move the LNB with little/no signal till you get a tuner lock.

thanks, tried that but no joy. will attempt again tomorrow. which satellite would you recommend pointing the dish to?

point the dish to the weakest satellite try hotbird regards john

The dish reflects the signal onto LNB. Are you sure you are moving LNB the correct side? 13e lnb will be slightly lower than 28e. Perhaps posting picture will help?

The Android-app 'SatFinder Lite' will show you exactly where the satellites are. See

I'd point the dish at 19e.

Hotbird is west of Astra2 so hotbird lnb goes east of the astra2 lnb and lower.

Is this how it is set up?

Looking into the dish, it should be left to right 28.2 , 19.2, 13, 9e with initlal setup on 19.2 for 4 lnb,s.
Its a case of balancing off each lnb and compromising to get reasonable signal ..... don,t forget the skew on each Lnb ... even more important on a multi lnb setup.
Providing you align on the correct satellites :) with only 2 sats shouldn,t be tooo difficult, but need to get some signal measurement going.

With my marginal 28.2, far easier with 2 dishes!

... but need to get some signal measurement going.

Your smartphone is enough for that; and it also allows for zapping.

Thanks for the replies guys , will take on board all comments . when I'm at parents next will try all suggestions.
I had Astra locked on 99% signal, then slid the other lnb across the bracket and couldn't get nothing on hotbird. I event skewed the lnb bracket.
Love setting up boxes and satellites more than than programmes they offer. :)

Slightly off-topic are there any satellite fayres around the country worth attending? They might be incorporated in other AV road shows but will have satellite stalls. Cheers

Dish aligned to 19.
Looking at the dish 13. Will be to right if centre lnb, 28.2 will be to left of centre lnb.

I think that trying to get 28e to 13e on a 80cm. dish is a little ambitious, but then what do I know ? :confused:

i think it can be done with the bracket.... but then what do i know :)

I've done this before with an 80cm dish for 28.2e, 19.2e and 13e with the focus on 19.2e.

I used a Vu+ Android app for the signal meter and to zap to channels which was really helpful - worked fine with my Technomate box, but looks like there's some new apps for that now.

Also if you only have two LNBs you might want to align it to 19.2 and check you are receiving that, then add 28.2e and check that's OK. Finally tighten up the bolts and move the first LNB from 19.2e to 13e.

I am considering giving this a go with an old 80cm round dish, do I just need to get this as my shopping list ?

Multi LNB Holder x 3
3 x Sky/HD lnbs (40mm)
satellite cabling and some F connectors
DiSEqC v2.0 4x1

Found most of these bits and bobs off ebay for 5-6 quid each

I think that's about right. Make sure that the dish arm supports the bracket and also the LNB fit on the bracket and you should be fine.

I'm hoping that if weather improves by the weekend I will have another go at dish alignment

Perhaps you should leave your coordinates here.So someone could calculate for you the degrees of inclining the rail.Normaly you align dish on 19 E .Then put multirail on it and incline rail view forward to dish left site up and right site start down by 10 degrees and then LNB 28.2 must be left site and 13E right site.Move LNd 28.2E until signal is good .Then move LNB 13E till signal.Then optimize by moving perhaps rail up or down.If you can write dutch put the question on sat4all because there is a specialist cold sprietje who calculates it for you.

Thanks , going to try this at the weekend. align dish to 19.2 and then looking at dish 28.2 left and 13 to right of 19.2 - thanks!
my co-ordinates are:
Latitude: 52.7504°
Longitude: -1.2030°

All sorted! Thanks for all the advise, had to increase my elevation a couple of degrees as to that as show on dishpointer but that would have probably been to mount level against chimney.
Once I had lock on 19.2 the others were easy to find.
I may have to go and tweak the 28.2 lnb as on some transponders some signal would be around 50%.

Yup thanks for the advice, got my kit up and running that 6 quid multi lnb holder from ebay worked fine has all the bits just make sure one of your lnbs has a long body (inverto black ultra lnb) works perfect, with a bit of lnb twisting and turning by 2-3mm am hitting 70-80% on all 3 sats but this is with a 100cm dish.

Far better then motorised for me since I can now flick instantly between all 3 sats and a million channels, not bad for spending 30-40 quid !

This pic is from another member(thanks to him) but illustrates it perfectly he shows you how important that angle of all 3 lnbs is, without that angle you won't pick up properly I think.

I got 30% signal on my hotbird and twisted it 2-3 degrees left and suddenly hit 75%, did same on my 28e one but only got 5% so its worth just rotating that lnb a little left or right, oddly had great picture for 30% and it still worked but I think a good 70-80 if not the 90% would be great.
