problem with two recievers. - ABA DSS

**ccelectro** · April 24th, 2009

I have an elliptical dish, 18x24 with 4 dual lnbf . On one receiver I have 110 119, the second I have 110 119 and 129. Both have separate cable to switch, then from the two cheata switches to the lnbf. From the switches to the lnbfs, I have the 1 switch on the left side of the lnbf and the 2 switch on the right side. where my problem is, that when one receiver is on 110, the other can only pick up 110, and the same with 119. the signal is not there when this happens. I don't know how I messed this up, I ran through it about 25 times.

have you got these switches and dish grounded?i am running 119-110-91-82 from the same set up as you to 4 recievers.each lnb i have the 2 cables coming from it to a 3x4 zinwell then to diseqc 119-port 1 110 port2 91port -3 and 82 straight to the diseqc in port 4.i only have the 1 HD reciever.i had issues similar to you and it was caused by the switches not having good ground.

While grounding is a good thing to do, it may not solve your problems completely. If it does not, try getting 2 Zinwell 4x4s. Sometimes Legacy LNBs have a bit of isolation problems, that a DiSEqC will not filter, but using the 4x4, in your case - in conjunction with the DiSEqC, will solve it. Been there, done that.

Thanks for the input guys. I will check and make sure my ground is still good, I have a grounding buss bar on back of dish with switches mounted to it and also a ground block for my two cables running inside, my ground wire then runs directly to my service ground. If I don't find a problem in the ground I will order the 2 4x4 zinwells. Once again, thanks Snakebite and Sgt.

As you mentioned 4 dual LNBs without telling whether they are legacy or dish pro, you may want to take into account that:
1. Zinwell (or other non dishpro) multiswithches, work with legacy/standard dual LNBs only.
2. A 4x4 multiswithch can feed up to 4 receivers for no more than to 2 satellite locations.
3. Dishpro LNBs require a dp34 switch for up to 3 satellite locations or a dpp44 switch for up to 4 satellite locations; each can feed up to 4 receivers.
