Multi LNB or Motorised dish ? Size and rough cost ideas

Hello friends. Just an update. Got my new 97cm motorised dish and multi lnb system installed on my old 80cm yesterday.

I used the same installer who did my original installation and took him long time in horrible rain.

I was intending to have four lnbs on multi lnb but he could not get signals for 19,16 and 13 and ended up having only 28 and 23 on the fixed dish which was annoying but still better than having only 28 . The installer blamed the trees as he could not even tune any of those sats individually including 16 from the location I had. He said , only solution will be put the fixed dish on pole which is not an option .

See the pictures of dishes and the trees. My both dishes or on either side of my house . From my motorised dish , I can tune all sats except 23 which does suggest there is some blockage on the line of sight .

I am definitely getting improved signals on all other sats . Have not checked all yet but will do some more testing over next few days .

I have now multi room setup via DISEqC switches which is great but I have only single cable in each room. I have two boxes in my living room. Can I use some kind of splitter to share the signals so can use both boxes (obviously 1 at a time ) . Please recommend if any. Currently I am using loop out option to share my fixed dish on other box but for motorised dish , I can't think any good way. I can't use any plugin either as one of the box is Viark .

Thanks for suggestions and help previously . If any sat enthusiasts/specialist is based in Manchester and happy to help in getting remaining two please pm me. Unfortunately, I can't do myself because of the height and I don't have a long ladder.

Unfortunately I'm off to Bristol tomoz am,
I don't think you will get 16 between 13 and 19 , there simply isn't physical room,
I have 13 19 and 28 on a 65cm at J17 , 23 MAY be possible, but it would be very tight,
IIRC , I reckoned 6degrees was the closest I could get on a 65cm, so on your 97cm I'd guess 23 is possible, but I still think 16 would be too tight.
 
On your multisat satellite dish your installer has
Used the right side of the arm for 28 and 23
That was the only clear line of sight with the trees Unless you move instalation away from the trees to clear line of sight You will not recieve 19
as the prime focus l.n.b

I am not sure but I think he did 28 on right side and 23 on east side but I was expecting otherway round. I told him few times to do that way but he kept ignoring me and said this is correct way because the signals bounce that way on arc and kind of mirror image.

Thanks. Yes I was hoping to get any combinations to get another sat was thinking 28 , 23 and either of 19, 16 or 13 which ever he could get but he did not get signals on any other except those two
 
I take it that pic of the trees was shot from beneath your fixed 80cm dish?

Is the fixed dish pointing somewhere to the far left of the trees pictured and are they the only trees opposite?

Taking into account that there's an apparant obstruction somewhere, and the distance between the dish and the trees which would in turn determine the trajectory. It could be that the line of sight for 28e and 23e passes somewhere either down the far left alongside the taller tree, in which case the left hand branches could be blocking 13e and 19e. Or if the distance is a bit shorter, with therefore a higher trajectory, you could be getting 28e and 23e through that gap in the top left of the pic, where you can see the sky. Whilst 19e and 13e could be be hitting the upper branches towards the centre of the tree where they're taller.

I think we all agree you're better leaving 16e to the motorised dish. Is 30w OK for you on the motorised now, as you had been suffering issues previously?

Was there not any room to move the fixed dish several feet towards the right? Since the apparant obstruction is on the westerly side it would've made sense to reposition the installation as further easterly as possible, to stand a better chance of getting 13e and 19e.

On the fixed dish, I don't understand why he hasn't spaced both LNB's equally from the centre? Doing so, any signal loss from being offset would've be shared equivalently. As it stands you've got the stronger 28e LNB, which tolerates being offset much better, in the centre, whilst the weaker 23e LNB, which doesn't, a lot further offset than it probably needs to be.

Having an LNB offset on the right of the bracket is the equivalent of repositioning the dish further left along the wall and having the same LNB in the centre (think in terms a mirror as once the signal bounces off the dish everything turns the opposite way around) and in turn towards the apparent obstruction. Which would indicate to me the installer chose this LNB placement for a reason other than avoiding the apparent obstruction.

The reason your motorised dish isn't picking up 23e could be due to that sat now being prioritised by the tuner assigned to the fixed dish. Using USALS I don't think the motorised dish would stop at 23e unless a recording was taking place on that sat via the fixed dish. Try temporarily disabling the tuner belonging to fixed dish and your motorised dish should pick up 23e again. Same rules should apply to 28e.

If you had access to a ladder and you're looking to add an additional sat to your DISEqC switch maybe you could refocus your zone 1 dish on 19e now that you've got 28e on the 80cm?

Thanks mate for the detailed reply and suggestions,.

Whilst 19e and 13e could be be hitting the upper branches towards the centre of the tree where they're taller. Yes the trees are thinner on left side so probably enough gap to get 28 and 23 and 19, 16 and 13 have been blocked by the taller trees.

I think we all agree you're better leaving 16e to the motorised dish. Is 30w OK for you on the motorised now, as you had been suffering issues previously? Yes, that seems to be perfect with high SNR.

Was there not any room to move the fixed dish several feet towards the right? Since the apparant obstruction is on the westerly side it would've made sense to reposition the installation as further easterly as possible, to stand a better chance of getting 13e and 19e. Unfortunately no further room , both sats are actually on extreme corners of my house . Fixed dish on left side and motorised on right side . we actually installed the fixed on same location as per the existing sky mini dish so can utilise existing cables and to be honest any other place would look bad with two big dishes together. I dont think that would solve the tree issue either because if I move it more toward the motorised dish it will even block the remaining two sats.

On the fixed dish, I don't understand why he hasn't spaced both LNB's equally from the centre? Doing so, any signal loss from being offset would've be shared equivalently. As it stands you've got the stronger 28e LNB, which tolerates being offset much better, in the centre, whilst the weaker 23e LNB, which doesn't, a lot further offset than it probably needs to be. Not sure but i got the feeling he was not really used to doing the multi sat setup as often as the motorised. by the way, I am actually getting higher signals on 23 than 28. so looks like the dish is more toward 23.

Having an LNB offset on the right of the bracket is the equivalent of repositioning the dish further left along the wall and having the same LNB in the centre (think in terms a mirror as once the signal bounces off the dish everything turns the opposite way around) and in turn towards the apparent obstruction. Which would indicate to me the installer chose this LNB placement for a reason other than avoiding the apparent obstruction. Not sure, all I know he spends nearly 2 hours playing with those 2 lnbs and at 1 point he was not even getting 28 and 23 at same time. Not sure because that was a particularly challenging installation or lack of experience. He even thoughts something is wrong with the bracket itself.

The reason your motorised dish isn't picking up 23e could be due to that sat now being prioritised by the tuner assigned to the fixed dish. Using USALS I don't think the motorised dish would stop at 23e unless a recording was taking place on that sat via the fixed dish. Try temporarily disabling the tuner belonging to fixed dish and your motorised dish should pick up 23e again. Same rules should apply to 28e. Good point, but i was actually checking 23 when the fixed dish was not set-up. he installed motrised first so was checking all sats and could not get signals for 23 but will try again .

If you had access to a ladder and you're looking to add an additional sat to your DISEqC switch maybe you could refocus your zone 1 dish on 19e now that you've got 28e on the 80cm? I have scrapped my old Zone 1 now and no chance my Mrs will approve third dish now. Hopefully someday @[B][COLOR=rgb(41, 105, 176)]steptoe[/COLOR][/B] be able to help (finger crossed).

You can use a priority switch for that. The slave box will work when the master box is in standby.

searched the question on the forum and have found many posts strongly suggesting it is not safe to use a splitter on sat so had given up the idea but if it is possible with this priority switch then can try. How this works and which switch to buy?

I haven’t used one myself, but it came up in my thread.

My understanding is when the main box is in standby, you second box can use the dish.

Sorry, I took your thread off on a tangent and was admiring linesman's 5 lnb setup.

The app steptoe recommended is pretty good, I've been using it too.

How far are the trees roughly from your dish?
