Spaun multiswitch & FTA

**jimbo123** · 13-01-09, 10:51 PM

Hi all,

Just got my hands on a and a to go with it.

Now reading the details on the terrestrial connection the states (bottom of page 10)

It is not recommended to connect aerials directly. Selective devices should be used to
avoid interference., e.g. FMP 30, VFM... F or MBV... PF.

From what I could find, I think the is just a Spaun bandpass filter. Can anyone recommend something that can be picked up locally,.. Melbourne,.. for this task ?

Any help would be much appreciated.

That FMP-30 seems to be just an FM band pass filter. Looking at the pdf it has your unit and it's directly connected to the multiswitch! I would just try it and see what happens. I wouldn't think you'd damage anything. At worst you end up with degraded signals both sat and terrestrial.

G'Day Cobber,
The FMP30 is an 87.5 to 108 MHz bandpass filter for the FM radio band.
No good for the terrestrial TV if that's what you had in mind.
I haven't checked but should be something similar available.
Let us know what you are trying to achieve?

All I want is to connect my FTA aerial and have it combine with the SAT inputs so that I can run a single cable to my outlets and then diplex out to FTA/SAT as required.

My concerns were around the warnings in the manual and written on the 5502 that advised not to connect an aerial directly to the unit.

So 2 things I guess,... I'm not sure why the warning is there? and if its valid, what do I need in between my aerial and the 5502.

So, still a bit confused.

Thanks for looking

G'Day Cobber,
Methinks you have gone overboard with an expensive item designed for large installations. A bit of an overkill really.
When all you need are diplexers. They have low pass for VHF/UHF and high pass for Satellite.
You could just hook the Spawn up direct, but you could end up with mutual interference.

Overkill,... perhaps.

My needs are for 2 sats, dual LNBs at each and terrestrial; all to be delivered to several points within the home, prolly 4 or 5 active.

Dual LNBs are obsolete. You would have to use Quad or Quattro.
The ones commonly available (mistakenly called Dual) are Twin with two totally independent outputs.
The installation, as you envisage, is going to be a lot more complicated than you obviously think.
Don't ask me to design it, someone else may be foolish enough to try.
You'll need a heap more gizmos than you have at the moment.

Is that right?

Thought a 5 in 8 out did all that for me?

Yes, 2 twins, one to each dish,.. going to each pair of H-V inputs with an aerial feed.

Methinks you had better re-read the data sheets.
There is no way of achieving this with them.

Put me out of my misery and tell me what you paid for them?

the hardware all looks good to me. I can't see why you think it won't work can you explain?

You obviously missed what I said.
Twin LNBs have two independent outputs, each switchable H/V.
Quad LNBs have four independent outputs, each switchable H/V.
Quattro/uni LNBs have 4 separate outputs:
High Band.......H + V
Low Band.......H + V

There is no way that I know of to have multi STBs controlling two dishes and terrestrial via a single Co-Ax.

Perhaps with multiple cables, certainly not with a single co-ax.
Yes, with multiswitches and diplexers.

Please have a good look at the configuration drawings.

You use a multiswitch like the one mentioned above to achieve this. Twin lnb's will work fine also.

I'd already clarified my post.
What I intended to mean was with his Spawn units.

Seems to be mis-understanding here.
You show me how to have Multi STBs controlling two dishes via a single co-ax?
To use the analogy I used in another thread:

It would be like having a car with four sets of controls, you in the RH seat, your wife along side you, and the two mothers in law in the back with their own sets of controls.

As I said above,.. I want to deliver those resources to wall-plates around the home via one cable.

On this cable-end there is NO intention to have multiple STBs, I don't think I ever that anywhere. Just like a 'normal multiswitch setup. Diplex,.. FTA cable to TV, SAT to the STB,.. or one, or the other without the diplexor.

**beer4life** · 20-01-09, 03:15 PM

Go ahead, it's your money.
Don't tell me that someone isn't going to plug another STB into one of the other outlets.

To do what your trying to do, you will need, as Beer4life has said, diseqc switches and diplexers.

Your shopping list would end up as something like this for a 4 way system.

2 x 65cm Offset Dishes (SDJ6501)
2 x Acer twin LNBF LO 10.7 (LNBFTU)
1 x 3 wire End of line multiswitch (Spaun SMS3403NFI)
1 x 2 wire End of line multiswitch (Spaun SMS241F)
4 x 2 way DiSEqC switch (Spaun SAR212F)
4 x Diplexer (Wall plate fitted) APO2C2
4 x Wallplates (APO2C2, APO2CFOX2L or # APO2CFOX2R)

This would give you what you want, but is quite a bit different to what you have as you can see. The equipment you have is not designed for what your wanting to use it for. It is for much larger installs. Although it would probably work fine even as an eol unit, you would need to change the lnbs above to quads so that you can cover the high and low h/v inputs. Just keep in mind that you may get unexpected results from these multiswitches in your configuration.

Thanks Cobber,
It was getting beyond my comprehension to understand why he bought those items without consulting the Gurus here.

So what is it that Jimbo purchased actuall used for? It's has 2 Horizontal and 2 vertical inputs which I would of thought would be for 2 twin lnbs pointed to 2 different sats?
The way I would do it myself would of been to use 2 twin out lnb's each going into their own 4 output multiswitches and then use 4 diseqc switches that go to each wall plate for each receiver. If terrestrial is required you can get diseqc switches that take a terrestrial input and diplex the signal so a 4 way splitter for the antenna is required with the outputs going to each diseqc switch with a diplexer at each wall plate.
