One satellite dish 2 satellites astra 28.3 & hotbird 13.0 + tv aerial

[tojo-mojo]

First post, please be gentle. I have spent the last 6 months reading threads on the forum and now i have a question for you keen satellite fans. I live in a converted house ( one house into 2 flats) On the roof there will be installed soon a satellite dish 1.5 meter with multi feed 28.2 astra and 13.0 hotbird & a tv aerial. What i am trying to achieve is to be able to run one cable to each flat with both satellite and tv aerial signals. I want to be able to watch either satellite or tv in 3 separate rooms per flat. can anyone help me with an idea as to what i need or indeed how to make such system work.

1.5m is complete overkill for what you want - an 80 cm dish would do just as well.

For the satellite side of things put quad lnb's on both 13E & 28E outlets.

At the top of the downlead from each room put a 4 way lnb switch then connect each lnb to ports 1 & 2 of the switches. (You can buy 2 way switches but a 4 way gives you the chance to expand the system in the future with minimal fuss.)

You should be able to use a triplexer to put tv signals & DAB radio as well ontro the same cabling. One of the installer chaps will be able to help more with this (I removed our old aerial when the Borders went DSO in November 2008 as the DTT signal was hopeless here.... So I dont keep up to date with aerial side of things)

I second the view that 1.5m is overkill (massively so!) and 80cm will do just fine.

 

[hexah]

If you are renting out one flat, include another quad LNB for 19e because anyone wanting 13e will almost certainly want 19e.

So that's 6 points in total ?

You either want two octo's, plus 6 switches, plus 6 triplexers. Or which might end up cheaper, and certianly easier to wire, use a 9 in 8 out multiswitch, and 2 quattro LNB's. Either way use triplexed wall plates to split the signals back up at the rooms. Using the quattro's you might want to go for a 1m dish, as there will be more loss on the system, but an 80cm should be OK. I totally agree with the above though, 1.5m is way overkill, hope you haven't applied for your planning permission yet.

9 wire switch would be the neatest option I think.

Vision V9 would do the job, and if you want to make it look really swanky use a Visiosat Bisat dish for the feeds, although 80cm standard dishes would be fine that far south.

I've been chucking the exact same setup in properties all over kensington and Westminster for the last 6 months

Levels are good and the dish also looks quite good too.

If i remember i'll take a picture of the one i'm working on monday and post it up tomorrow night

Can anyone give me an idea as to where i could get a wiring diagram for such a setup. The dish is massive but i already had the dish and my uncle who is the proprietor of the flats has already asked the council if it was ok to fit. Hence i didn't really want to go out and purchase another dish.
I understand sort of what is the basic functionality of this setup but if i could see a wiring diagram that would make me feel a lot easier in how i will get this project done.
My main questions to you professionals is, well i hope i have got this right, i would like to place the multi switch somewhere in the loft, i would have one quattro lnb on 28.2 and another on 13.0 hotbird (8 cables in total), 1 cable coming from the aerial (telves dat 75) so i have 9 cables coming into the multi switch. Flat1 I have one cable coming into the sitting room, i then want to be able to watch either sky or hotbird or normal tv in that room, this is where i get confused not sure what i do next. I wanted the same connection in the kitchen and bedroom if possible.
Any help would be good, sorry if this sounds stupid to you professionals but i really want to get the project done on my own if i can.

If I were doing it I'd use 9 in 12 out multiswitch, with Astra 28.2 as port A, then run two or three cables down to the sitting room, this would give you the option of Sky+, or a Freesat PVR and also a separate receiver for Hotbird, plus a return feed to the loft, which could be connected to either or both of the bedroom feeds to watch the Sky/Freesat, or Hotbird receiver., then a single cable to the bedrooms

 

[tojo-mojo]

Hi posted something earlier not sure where it went though. Is there any chance of some sort of wiring diagram please.

 

[PaulR]

Sorry, it went into the moderation queue and it was, er, overlooked.

Fixed now!

 

[hexah]

Where are you going to put the 1.5m dish, and how are you going to anchor it?

 

[tojo-mojo]

Hi Hexah

the dish is being fitted to a 3 inch scaffold type pole at the bottom of the garden in 40 x 40 x 40cm concrete.
I am getting all confused on this multiswitch system. I wanted to be able to hook the signals down to the tv through one cable if it was possible.
From what i understand i think i have got it right 9 cables down to the multiswitch then one cable down to each tv, how do i then plug that one lead into both separate receivers and the tv this is where i am lost????

 

[Lazarus]

I'm still bemused as to why you want to fit such a big dish ................. read over the Posts a few times but I'm none the wiser.

 

[hexah]

Likewise, though very glad its not going near the roof...

 

[A nonymous]

A dish that size being used for such powerful satellites could in theory overload the switch with too much signal. You may need to attenuate the feeds coming into the switch if V9 is used.

As for a wiring diagram, you don't need one.

You have to use 2 Quattro lnbs ( Not Quads) with individual V/L, H/L, V/H, H/H polarities and a throw out arm for the second lnb on 13e.

Line the dish up on the weakest satellite of the two and then run each cable from each polarity on the lnb to the corresponding input on the multiswitch, The Aerial/s will goto the terrestrial input on the switch

Sat A 28.2e is is at the back of the switch ( DISEqC A/A) Sat B 13e is at the front of the switch (DISEqC A/

You then run 2 feeds to each flat. Make sure you mark the cables as the properties furthest away from the switch need to go at the top of the switch which has a higher output than at the outputs at the bottom of the switch.

I am sorry if my messages are pathetic and probably wind you guys up i just cant seem to get my head around this multiswitch setup.

So basically if i understood this right i will have 9 cables coming the dish into the multiswitch. ( 4 from 28.2 and 4 from 13.0 + aerial)

Flat 1
I will have a lead from output one into my sky box lnb in. Then i will have another lead from the output 2 into the tivusat receiver for hotbird Job done

Flat 2
Same as above but i will use output 3 and 4.
How will i get the normal aerial to work if i only have 2 leads going into the receivers???

I was hoping to able to run all down through one coaxial cable to the tv sets.

once again sorry for troubling you professionals on a sunday evening

[Lazarus]

Sorry to keep harping on like a stuck record, but can you please tell us why you want to use an unnecessarily grossly oversized dish for this project?

 

[tojo-mojo]

Hi Tivu, its because i already have the dish thats all. No other reason.

 

[Lazarus]

Ah. Can't argue with the principle, as I'm an inveterate re-user myself.

But there may be problems:

eg

Overloading of multiswitch (as stated earlier)
Very narrow beamwidth, which means precise alignment required
Ditto with getting the non-focal Satellite optimised
