need diseqc switch...??

[mpjassal]

Right now I'm using EMP 4x1 diseqc switch......but its not doing all the job.....I have 3 legacy lnb for 110,119(&118) and 129w.......whenever I switch from one satellite to another I don't have signal on it......then I go into my antenna setting turn off lnb power then turn back on to get the signal on that particular bird.....

I have 118/119 on port 1
110 port 2
129 port 3
None port 4

I'm getting all the channel whenever I scan any of this satellite without any problem..

please any solution

is your system grounded?

please any solution1 of u r lnb is not good . & use axing disqic .. Switch .. Which are way better than emp ..

is your system grounded?

no.. and I don't know why I need it. this will work for me if this can fix my problem

I don't think my lnb are wrong bcoz I'm getting same problem on all......

If your system was grounded you probably wouldn't be experiencing the problems that you are - good reason for grounding.

Do you know why I need to ground it....???

So that the switch will work correctly .

Stray electrical currents on the shield can cause some two switch setups to malfunction, this is cased by bleed-over of one 22 KHz Diseqc signal from one switch to the other.

The coax shield is not that good of a conductor, and some coax is cheap, it may not have enough shielding to knock down the cross talk.

Using a 12 gauge (or larger) solid copper wire from the switches, tied directly to the nearest earth ground will help cut down of the cross talk.

It will also cut down on any possible ground loop problems (current flowing from one receiver to the other) when using two or more receivers located in different parts of the house.

where can I use grounding blocks on wire......if I using two receivers then Do i need two grounding blocks on each wire...????

If the switch is metal, and has a mounting hole or tab, then you do not need the ground block(s), the metal case of the switch will ground the coax.

here my switch if I take it out of cover and screw it with my dish.....will be fine for me
