diseqc 2in1 reduse my signal 35%

Sometimes it is a problem with oxidation of the cable and then the signal level falls. You need to clean up the Central core of the cable and check the connector

Re: diseqc 2in1 reduse my signal 35%

Yes it is right.. But in case of dreambox long wire creates more problem.. I reduced length of cable from box to switch so my problem solved..

Diseqc switches usually lose between 2-3db depending on the brand of switch, this has no bearing on whether the switch is connected near your dish or behind your receiver the signal loss would still be the same.

Same was happened with me???????????

Can a 2-1 DISEqC switch pass the signal from the two inputs simultaneously?

In yes, out no.

It's a switch which switches one of the inputs to the output. During this process you lose a (very) little bit of your signal strength. With a good switch you won't realise this loss.

Dear friend
You probably have a faulty DiSEqC Switch.

Buy a new one with better quality (not from e-bay)
but first...
check your settings of your box.

Maybe you have miss to check or uncheck something.

Take a careful look at your settings and inform us.

Best regards

Yes it is faulty switch.

for the future usualy Switch is placed close to the dish and if you have amplifier you put it close to reciver.

I wouldn't put amplifier near the receiver ... in this way you are going to amplify a signal with a bigger noise.
Typically amplifiers should be kept as near as possible to the signal's source, where you have a better S/N ratio.

Re: diseqc 2in1 reduse my signal 35%

I couldnt agree, I test it few times and best result is closest to reciver.
There is no need for amplify signal close to LNB, but when signal is lost throught the cable.

Then you had an old or very cheap cable.
I am using since a few weeks a 50m cable from receiver to switch and have no diseqc problems.

I respect your opinion and tests, but on the web you will find plenty of pages like this:
__hxxp://www.satcure.co.uk/tech/lnbamps.htm

Just quoting from the above link:
"The amplifier will give no benefit as it amplifies only what is there - signal plus noise - and adds more noise.
To spell it out: Connect your receiver as close to the dish as possible."

or ...

"The amplifier must always be near the input end of a long cable. If you put it at the output end, you are simply boosting the signal and the noise the cable has picked up, so you are hardly any better off!

If, when you do the test, you find that the receiver does not work better when connected close to the LNB then an amplifier will NOT help. In fact it will almost certainly make matters worse."

Re: diseqc 2in1 reduse my signal 35%

Some post make me think cause me cable is almost 100% uncover from rain and sun and near 7 years old. too cheap and easy to replace it if it will do me any good. my signal without the diseqc was near 75%. whats the rate for that poor, good, great?

hi kostis

75% seems good to me (not poor, but surely not great either) - I don't expect problems with this.

yes no signal loss so fur except from very rainy days, and the last lnb change was made with no instruments use so i take it the wire is ok for now.
