Is there a maximum number of tuners on Twin LNB

Is there a maximum number of tuners that can be connected on a Twin LNB

The Twin has a max of 2 tuners, to get more you have to replace the Twin.
The DP Twin also has a max of 2 tuners, but you can add an external switch to feed more.
The DPP Twin can feed 2 receivers, both of which can be dual-tuner models.

EKB: What's this Twin LNBF I've heard about?

 

[DishInstallAdam]

I am have just done a site survey and one of the 311's say it has a twin LNB, there are two 311's and one 322, one of the 311 is starting through its transponder test and gets to 2 of 5 and restarts at 0, is this a receiver issue or an LNB that can not support 4 tuners.

It supports a maximum of 2 receivers, each of which may have 2 tuners. What you are trying to do does not work since you are hooking up 3 receivers. You need a switch or a DPP Triple LNB on a 1000.2 or 1000.4 dish.

unless its an old Legacy setup then its only 2 tuners total

 

[joshua.mcglothlen]

if its a quad then it can handle 4 but you said a twin so nevermind

Hard to say. Was this a working installation before? I wonder if the LNB is really a DPP twin... There was a way of connecting up 2 solo receivers and 1 duo receiver using a single DPP twin. Totally unsupported of course.

 

[bpjester]

not that it matters now since he did the service call yesterday, but i'm sure by "twin" he meant dual lnbf. Im guessing he was looking at a dual dp quad lnbf. One output each solo receiver and two outputs for the 322. Otherwise there was a switch somewhere in the system. Or he is at a bad install where e

 

[bpjester]

to continue.. .3 receivers could be fighting over 2 tuners which ive only personally seen done using d* splitter. Just from my own limited personal experience.

Huh??

Maybe he saw dp twin as the lnb in the check switch summary, but missed a d34 or d44 as the installed switch. If there were 2-311's and a 322 on-site, there was no way they were running off of a single dish/dp twin configuration without a d34, d33, d44 switch. There could also be a second dish somewhere tucked behind a chimney or next door at the neighbor's house.

Yes there is. You can run two solo receivers and a duo receiver off a single DPP twin. I think this is rare because most Dish installers don't know about it, and as I said above, it's not a supported configuration.

 

[BobaBird]

What happens when one Solo wants 110 and the other wants 119?

 

[TheKrell]

Duo receiver DPP tuners can obviously command the switch to switch. Solo DP receivers could also plausibly be made work off either side of a separator, but Dish has added no software to do that. So, they must be placed on the TV1 output of the separator. With a DPP twin, you have two cables and two separators possible, with two TV1 outputs sitting there inviting you to connect up a solo receiver.
