Switch Problem

[johnny cash]

My setup is 82,91,110,119 on a 85cm Elliptical digiwave dish and 129 on another dish. Standard lnb's and 2 switches 8 into 1 EMP Centauri switch, going to 2 JynxBox v2 receivers. My question and problem is that i got perfect strength on all lnb's before the 2 switchs but some how losing power out from them going to the receivers. Should i be using another type of switch or should i add something? Thanks for all your response back any info it will be much appreciated.

And lot of receivers don't like sharing lnbs. Does Q/S improve when one of the receivers is powered off?

A grounding block, if not already installed, would be a good place to start.

Your always going to loose signal going through a switch, or anything else attached to the coax coming from the LNB, even a splice will add 3 dB of signal loss.

Now are we talking about the "S" or the "Q"?

If you are loosing 10 to 20% of the "S" then don't worry, the same for the "Q", but if it's over 30% or more then you have a problem, check the type of coax used after the switch, is it the same stuff as from the LNB?

Some coax is for CATV or off air TV only, it should not be used for satellite systems.

Another problem could be the types of LNB's you are using, they should all be the same type, because if they are intermixed types/manufactures then you could have problems going into the switch, some LNB's don't play nice with each other.

Legacy LNB's do not like to play well with DP or some standard type LNB's, and they don't work too good if your trying to split them between two switches.



Questions for you:

Are all the LNB's the same type and manufacture?

How long a run of coax from the LNB's to the switches?

How long a run of coax from the switches to the receivers?

What type of coax are you using, what are the markings on it as far as frequency response?

And lastly, are the switches grounded?
