Satellite Coax F-Type Patch Panel

SachaJ

Anyone know where to pick one up cheap enough?

There is this on eBay but the shipping is expensive

What about buying a bag of F-Type couplers for £10 off eBay and cutting a 19" length of aluminium? Then drill and fit? A lot of messing though to save the shipping cost.....

That's what I would do.

Why do you need one? Why not just get a 16 way amplifier??? How many sockets do you require?

I'll have an Octo LNB but up to 48 points in the house (24 twin cables) so will need to chop and change as needs require (ie. rearrange a room with the tv in a new location)

Put a Quattro some sat splitters and 3 x 16 way Multiswitch units

Or 2 of these bad boys:

There's even a 28 output one.

I was going to ask how you would feed 2 multiswitches from a single LNB as the one mentioned isn't cascadable, probably not possible from a single quattro LNB but I see from the EMP website that it's compatible with a quad LNB also.

I quess the answer is an Octo LNB - 4 feeds to each multiswitch.

Is it possible to split each quattro LNB feed to 2 multiswitches?

You can use a 2 way passive sat IF splitter for a Quattro. Enough to feed four multiswitches. You can get four splitters in one case.

You can use a trunk amp on each splitter output and then feed 10 "trunk splitters", they have 1dB loss on trunk and 8dB or 11dB (I forget which). That then feeds 11 x Multiswitches, so total is 2 x 11 x 16 outlets.

A 90cm to 110cm dish can feed up to 121 or 242 multiswitches. Each of the 4 x 11 (or 4 x 22) initial feeds feeds a quad trunk amp feeding 10 trunk splitters. So up to 3872 outlets or 1436 PVRs.

You do not need cascadable switches.

I built a system using many "17 x 16 Multiswitches" fed by 4 x Quattros (four different satellites), Cable broadband to 1/2 the terrestrial inputs (passive version allows 5MHz to 65MHz upstream) and helical filters on off air aerial fed other half of terrestrial inputs. Then each dual PVR outlet with a Sat/TV duplex splitter to give 2 x Sat, 1 x BB & 1 x BandII /BandIII/TV outlet on the plate. Sky compatible as 28.2 on 1st Diseqc position.

Hi Lads,

Looks like 65 pounds for one of these from a company in England, they promise the connections will be isolated.

I think I need isolation as I am using sky red eye in a couple of rooms so I need the sky 5v passed back for the red eye booster I am using.

Any cheaper alternatives? I could get a punched 19" empty rack and 24 type f connectors but again I'm wondering can I get type f connectors with rubber for isolation?

I have sound and network racked already so I reckon getting this racked too will sort me out.

Does the panel have to be metal? Maybe a sufficiently thick piece of acrylic sheet would do then you wouldn't need to worry about insulation. Easy to cut to size and drill too.

randombar

Now that's thinking outside the box

Had a look round there on the interweb for a ready made and surprisingly there are no non-conductive 19" patch panels about?

SachaJ

I can't remember the diameter of the f-type connectors but assuming they are 8mm, something like this may work

http://www.ebay.co.uk/itm/8mm-Cable-Grommet-20-Pack-CB809-/150587902691?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item230fbd0ae3

Not 100% as you'd be losing 5mm of length off one side of the connector.

Or have a look for a 12mm (ish) blanking grommet and drill out your 8mm from the middle.

Why does it need to be non-conductive? The inner conductors of the cables will be isolated from each other.

Sky Red Eye uses the external coil (I think) to pass voltage to power a red eye booster.

You mean the cable braid? Electric power can't travel solely on 1 conductor. Isn't the braid the return/ground/common/whatever you want to call it?

Yes I'm guessing it's being used as the negative or something along those lines.

Peter Rhea

Look at any metal-bodied splitter, for example. The outer part of the sockets will just be part of the metal case.

randombar

The Red Eye splitter isn't metal bodied I'm afraid, perhaps the outer is always negative and isn't a big deal. Might do some testing to find out I guess.

Anyone know any different??

Peter Rhea

'Red eyes' will work with any kind of splitter that passes DC & also the remote control signal frequencies.

What problem do you think you are going to encounter, that hasn't ever arisen for anyone else?

randombar

I am just wondering if there will be any interference between connections if the negative is shared across them all? Some will be sat connections others terrestrial etc.

I guess it's trial and error really.

Peter Rhea

Shouldn't be problems if everything is connected to the same power installation (i.e. all powered from within your house).

Would be different if there were say, UPC cables or something like that, from an outside source.

You've me convinced, now to find out where will I pick up one of these or pick up the parts?
