only one power supply needed, that i know.
i can't remember if you have to split it before or after the power supply

If you want to risk the tuner at one box before.
If not behind or use a splitter with dc blocker at the leg with direct connection to the tuner.

The power inserter is sending between 12 volt and 24 volt up to the downconverter at the aerial via the antenna socket.
If you fit a splitter with dc pass between aerial and power inserter, the voltage is also transfered via the second leg to the tuner at the second box and thats not so good.

ok so if i split the cable coming from the power suppy transformer i.e. on the power supply there is a socket for the coax going to the aerial and then an outlet for coax going to reciever so if i use the f splitter from maplin can i split the coax coming from the outlet of the power supply transformer to two recievers? Thanks

There is no voltage at the TV socket of the power inserter. If you split behind the inserter there is no voltage problem.

Hi,
I am wondering is it safe to apply two power supplies to one aerial. If i have two boxes can i split the coax in the attic coming from the aerial and then send the split cable to two different power supplies and then two boxes from those power supplies. The reason I am considering using 2 power supplies is to safeguard the boxes from any voltage reaching the boxes.
Thanks

absolutely no no no , one power supply can run up to 4 receivers

ok
so you are saying it is safe to split the cable between the aerial and the powersupply so 1 leg will be coming from the splitter to the power supply then power supply to box then the other leg will be going from the splitter straight to the other box.
Is there any danger of voltage in the coax reaching the box because there is no voltage going from the power supply to the box but if it is split before power supply then goes directly to the box there will be voltage going to the box is there a risk to the box/tuner

With MMDS surely the Powersupply is running the down converter in the aerial.It is nothing to do the receiver.They are powered independantly.
Also, Sayguy99 can you please outline how the splitter you have recommended should be connected.Which leg should connect to the PSU and which direct to the 2nd box.This splitter has DC feedthrough on 1 leg only.Surely this is of importance to the set up.
I would have similar concerns as Erukus.It is for this reason i have split after the PSU, in the attic.
Thanks

Does anyone know where i can get a d.c. blocker to fit to the coax cable i have seen some f connectors with a d.c. blocker integrated into it but only on american sites anyone know any uk or irish sites that supply these?

You could use this splitter:
http://www.maplin.co.uk/Module.aspx?ModuleNo=9273
This one has power pass only at one leg.

hello... i want to make sure that i fully understand this thread..as i dont want to blow any of the boxes..by connecting them wrongly...
Can i ask again in my own words how to connect my starview box to my NTL MMDS sytem....
As other replies have said ...you connect the starview on one side of the power suuply so as you dont introduce a voltage ( the dc voltage thing) that may blow the power supply..or indeed the genuine NTL reciver.... The big question being which is the correct side...!!!
From the thread i am understanding that i should connect my Starview box on the co ax cable as it leaves the power supply and goes to the reciever,,,??? (and not between the MMDS aerial and power supply)
Is this correct....??
If it is correct, this would be the place to cut the cable and put a two way spliter in place,,so as i can connect my starview box....??? (and therefore any voltages..dc thingy... that may be introduced will not affect either box or the genuine power supply)
Really need ya input here to make sure i dont mess it up...Thanks guys... Billyie

Ok you have managed to confuse a nation with that post
You have not indicated how many boxes you intend to use from the one aerial.
if using one box run coax from aerial to power supply connect coax from aerial to the socket on the power supply labeled ANT then run a 2nd coax from the TV socket of the power supply to the cable box (reciever)
if using 2 boxes introduce the splitter shown above to the coax between the aerial and the power supply. Then run the second box from the splitter just be sure to follow the diagram on the splitter so one side will have power to aerial (i.e. the original 1 box setup) and the other side of the splitter will be directly connected to the 2nd box.

HI GUYS...
A bit confused by ya reply Erukus... i thought it was evident from my thread that i had an original NTL MMDS system in place....
and was trying to add a starview box into the system.. but i must have confused you..sorry...
But anyway..may i ask if after reading all threads again...would i be correct in saying that you can connect on either side of the power suuply..but you need to be very aware of the type of splitter you use.
If a splitter is used in between power supply and the aerial..you must use a splitter with dc pass(power pass)and make sure that only the original NTL MMDS box is Connected to the dc pass leg of splitter...so as the original NTL box can send its voltage to the downconvertor at the aeriel...while my Starview box can be connected safely to the other non dc pass leg of this splitter...
BUT..
If you connect a splitter between power supply and the receiver..you can use a very standard splitter which may not have dc pass because at this side of the power supply there is no voltage problem.
Would this be correct..???? I would need to be corrected if ya think i still have it wrong,,,,Thanks to Erukus..and any body whom can guide me on this ... Billyie
