5 bell receivers on a sw44?

[huet]

Hi, i have attached a schematic and i would like to know if its the correct way of connecting five bell receivers.

bell installed the 4 receivers and i will like to install myshelf a fifth.

sat; 91/82

4 hd 6131
1 4100

dish: bell

See page 13 of this install guide, it shows two SW44’s tied into 2 Bell LNB’s, this is the best way to use more then 4 receivers hooked into 2 Bell LNB’s.

The splitters have to be rated for 3 GHz and have one side DC passing, the DC pass side must come from switch #1 only, you do not want to power the LNB’s from 2 different power supplies.

Note, this will not work for Dish DP, DP+ or DPP LNB’s, you have to use DP44 switches for that.

thanks for your help.

Another option would be to use a SW44A & SW44 switch. Bell does not endorse the SW44A switch even though it does work. This setup would have less switches - 2 and give you up to 8 tuner/receiver output even though Bell only allows a max of 6 receivers on an account. 8 outputs can be beneficial if you have some dual tuner receivers in the mix. :thumbsup:

i found that 2 sw34 and a sw44 worked well...the sw34s, 1 on each lnb, splits the dual lnb to quad. the sw44 takes 2 from each lnb and makes 4 receivers, the other 2 on each lnb could either go to another sw44 or sw21's, as required by your setup (use sw21 for 1 or 2 receivers, sw44 for more)

I would recommend your sugestion as being the cheapest route to go if he just uses a 3x4 switch instead of what you reference as a SW34. If the OP goes into his local Bev store and asks for a...

You all must remember (some of you already know this, this is for that don’t know) that the bell LNB's use the DC switching mode (legacy LNB’s) to go between the L and R transponder polarities, so the switch needs to have 4 inputs, 2 for the +14VDC (1 from satellite LNB “A” and 1 from satellite LNB “B”) and 2 for the +18VDC (the same as the +14), the switch has to direct the switching voltage from the receivers to the respective LNB input and LNB (RX 2, LNB “B” +18VDC or RX 1, LNB “A” +14VDC), when the SW44 is used the LNB’s outputs are fixed at “ output #1= +14V, output #2 = +18V.

So a 3X4 switch wont work, you need one with 4 inputs. (2 ea +14V and 2 ea +18V, 2 from LNB “A” and 2 from LNB “B”)

This doesn’t matter if you are only using 1 or 2 receivers, then the LNB outputs will respond to the switching voltage from the receiver it is connected to, this changes when you add a switch to try and use more then 2 receivers.

ottid142, perhaps I used the wrong term, the sw3x4 or 3x4 switches I am using and trying to reference are zinwell 3x4

terryl, a 3x4 switech will work fine, I am using them right now. it takes 2 in from 1 lnb, the 3rd is for OTA, so remains empty. you need a 3x4 for each lnb to split to 4 signals, then 2 from each can go to sw44 leaving 2 each free for either diseqc or sw21 or sw44

[WillDekkard]

or . . . . . . you can use 2 3x8 multiswitches, placing 1 on each LNB(91&82). Then use 5 Dish Brand SW21 switches as the OP stated he needs only 5 outputs. If the OP needs to add any more receivers he can do so by adding SW21s(up to a total of 8).:yes:

A subbed Bell receiver will recognize these switches?

I was under the impression that the Bell receiver only worked with a Bell approved switch?

[xayoz]

this is what I am using with my sub, and it works fine. a zinwell 4x4 would not work as it uses 22khz, but the 3x4 does not as it is only for 1 lnb.

Nope the Bell receivers work fine with the 3x4s. When you do a switch check on the Bell receiver it doesnt even see the 3x4, but it will see any switch (SW21, SW44) you have connected after the 3x4. Basically I consider the 3x4 to be the satellite equivalent to a splitter.

It can be confusing. Any switch with the SW designation is usually a legacy switch from the providers whereas if it doesnt have any letters in front of the numbers it is a FTA switch. Alot of the FTA switches are or were originally Dave switches. An example of this is the Zinwell 4x4 switch which is actually labeled as being approved by Dave.

With two 3x4 multiswitches you need the following setup with the SW44. You can substitute a SW21 for the 2nd SW44 for a 5 receiver/tuner setup as the OP requested.

Below is the Bell "Un-approved" setup using a SW44A & SW44 switches. (Least amount of switches)
