Is there a way to amplify a DTV signal?

[terster]

Hi,

I have a question and i'd be grateful for any assistance.

I have a situation where a DIRECTV dis is installed outside. There is only 1 RG6 coax connected to it. It comes down the tower into a conduit that then enters the house.

The conduit is only large enough for 1 RG6 cable. I can not get more than one run in it. There is no other way at this time to run a 2nd line from the dish to inside the house.

Where the one run enters the house, I split the cable using a 5 - 2350Mhz (i think that's it) 2 way splitter.

I then ran an rg6 about 70 feet to a bedroom and i ran a 2nd RG6 about 30 feet to the living room.

I have all high quality compression DISH NETWORK approved fittings (Even though my system is Directv).

Anyhow, in the bedroom is an older Hughes receiver. In the living room is a newer RCA receiver.

My problem is... when both systems are turned on (or just plugged in to the wall outlet)... MOST channels go to "Searching for signal", on both receivers.

If i unplug one receiver... the other is perfect. If i unplug the other, than the first is perfect.

In other words, i'm only able to use 1 receiver at a time.

Does anyone know of a way to boost the signal enough on that 1 run, so that i can use 2 receivers?

I do understand that it's not realy made for it to work this way and that i really should pull a 2nd run from the dish to that second receiver, but again, logistically, it's just not possible at this time. So again, i'm hoping there is some way to boost the signal.

Strangely enough... not ALL channels are missing on both receivers when both receivers are plugged in and working. But most are, enough that it's really not working for me.

If it matters... the 2nd receiver (the one in the bedroom) will only be used a few hrs a night, a few weekends a year when i go to my mothers to visit (i bring my own receiver).

So, it's not then end of the world if i can't get this, but it would be nice for those times when i visit... to be able to watch some tv before bed.

And... unfortunately for me... she's a night owl and i really can't ask her to unplug her receiver just so i can watch mine. LOL

So again... does anyone know of an amplifier, filter, signal booster, something, anything... that would resolve this issue?

If i were to get an identical RCA receiver like hers and get it subscribed in place of my older Hughes.... would that make a difference?

I sure appreciate your time in reading all of this and any help that you can provide.

Sincerely,

Terster

P.S. I did try using a passive inline amplifier similiar to: S-SA01 Sadoun In-Line Amplifier ( signal booster ):

I tried it before the splitter as well as after it, and on each of the runs after teh spltter. It did not have any affect at all.

I left it installed before the splitter, but again, i don't think that this particular type of product is going to work for my situation.

Thanks again.

When you have both receivers turned on, they are both passing dc power to the LNB. They are both trying to tune a specific transponder/frequency.

I think your only option is to put a dc block on one of the receivers. Big but though. In this case when you want to watch something on receiver with dc block, the other receiver will also have to be turned on and you will only be able to tune in to channels on a transponder that the receiver that is passing dc to the LNB is tuned into.

You really need to get this:25-HFS21 JVI Satellite

Put you new receiver on the power-pass leg and the old one on the DC blocked leg of the splitter.

That splitter you put in is allowing DC to pass from both receivers to the LNB (and to each other!) and causing the problems you are describing.

In any case, you shouldn't continue using this setup. With two receivers hooked together like this, you could conceivably damage one or the other of the systems. When one receiver is trying to tune one polarity and sources 18V to the antenna, the other one may be tuned to another polarity and instead tries to source 14V to the antenna, you are going to get a net current flow out of the 18V source to the 14V source.

The receiver at 14V will have to sink some amount of this back current, possibly damaging components. The receiver at 18V will probably be OK, but it also could be damaged as it is trying to send current into a lower- voltage source.

By putting the power-pass leg of the splitter to the new receiver, it will function 100% all the time. The old receiver will only function correctly on the channels that happen to match the polarity that the new receiver is tuned to. Basically, you'll tune about 1/2 of your channels at any time, and if you want to tune the other 1/2, you'll have to change the channel (polarity) of the new receiver.

Thank you very much. This will help.

I know this is not the greatest setup, however it really is for only a few hours, one weekend every few months.

Thanks again, i just ordered the part you recommended.

Sincerely,
