The Zinwell WB68 Multi-Switch - HOW TO WIRE (28JAN2007)

The Zinwell WB68 Multi-Switch - HOW TO WIRE

The AT9 Dish and newer AU9 Slimline Dish have only four outputs. If you have a requirement for more than four, you need to expand your capacity with a Multi-Switch. Currently (28JAN2007), the ONLY DirecTV approved Multi-Switch is the Zinwell WB68.

The Zinwell WB68 by itself will expand the output capacity from four to eight. The Zinwell unit is powered by the satellite receiver and require no additional power source (such as a low voltage transformer) to operate.

In most cases, eight outputs should be sufficient however others may need more than eight. To increase the number of outputs beyond eight, a second or third Zinwell WB68 may be used. Outlined below are three common configurations of the Zinwell WB68 Multi-Switch. Notice when more than one Multi-Switch is used, the dish output must be split to accomodate two or more Multi-Switch inputs (see diagram).

Another consideration is having the correct output from the Dish, to the correct input of the Multi-Switch (e.g. output one to input one, output two to input two - this would also ring true if the main signal is split - output one to splitter one, splitter one to input one
on each multi-switch).

As a point of interest... The cable length from Dish to Receiver should NOT (according to DirecTV) exceed 100 feet. You may find that it will work beyond this length limitation and the last installer I spoke with said, he's had success in excess of 300 feet. Personally I would stick with the 100' rule and not risk signal loss during that must see show or event.

It's not difficult to wire the Multi-Switch into your system however if you do not feel comfortable performing this task, just call DirecTV and they can have a technican perform the work. At the very least, you will know what to a) ask for and b) know what to expect when they arrive.

Thanks for the revisions Hondo.

What is the frequency range required for the splitters if we need to use the 9-16 # of outputs?
Are these splitters available at local retail outlets? Home Depot?

wyllys 02-15-2007 01:34 PM

Will it work if only 3 of the 4 inputs are connected?
Also, do these work with the older 3LNB dishes ?

I was always told that satellite feeds from the LNB could NOT be split, is that still the case?

What are the correct freq. splitters we need? And where can they be aquired?

lunchbox902 02-19-2007 11:54 AM

you are correct that you can not use splitters from the LNB out to a receiver but in this case you are not going to a receiver you are going to a Multiswitch.

You can not pass multiple voltages (13vdc 18vdc) down the same cable at the same time. In the diagram above you will notice that the splitters and connected to the same voltages on each multiswitch so there is no conflict.

the frequency range would need to be cover the 250-2150mhz range that is coming off the slimline dish.

For this to work correctly or for any multiswitch connection to work correctly you would have to have all 4 lines connected. only 3 or 2 line you are not getting all of the voltages to the LNB for it to properly switch between sat location and /or transponders.

Sonora has what you need to amplify and split
Go to sonoradesign.com http://www.sonorastore.com/510.html and get PDF of spec sheet. It shows you how to do everything for an AT9 dish. I use the amplifiers and power stacker since my dish is ground mounted about 100 feet from house bringing total run from LNB to Zinwell to 6 receivers at about 225 feet average. I did the installation of the dish and all the wiring. When Directv rep came with my new DVR I had him meter my 5 signals and he said he'd never seen them that good so I know the cable run was not an issue. I don't need more than 8 outputs so I haven't yet had to split for 2 Zinwells

HondoHDTV 03-05-2007 05:41 PM


it is my understanding that you need one that covers 0-3ghz. you will also want RG-6 coax that is sweep tested to 3 ghz as well.


I would think not... I would double check with DirecTV or a DTV installation contractor to be 100% sure. additionally, I don't know if the Zinwell switch is the "only" one supported for the 3 LNB dish. being that you have the 3 LNB dish, you may have more options for Multi-Switches. Another idea would be to have DTV upgrade your dish to the new 5 LNB... they only charged me $19.95 for the shipping & handling - that would be the least expensive upgrade and they do the work.

Donnie Z,

you are correct! however as lunchbox 902 points out, each feed coming off the dish is fed to a spiltter and then to that specific input on the multi-switch. look closely and follow the wire in the schematic and hopefully that will explain it better.

lunchbox 902,

thanks for fielding the question!


excellent suggestion! I stuck with the DTV recommendation for the folks that don't do this everyday. I'll definately keep that in my bag of tricks - thanks!

Beck38 posted the response below in brackets to a different thread. I have two questions re: this: 1) has anyone else had a problem with the WB68, and 2) is it generally accepted that DTV will supply the WB68 at no cost?


[All WB68's ought to find homes in the nearest dumpster. Period. I had over 80 of them in MDU setups in and around Seattle (2 different companies) that were causing TONS of problems. ALL were replaced by WB616's starting over 3 months ago. ZERO problems since (771 errors on multiple channels, multiple satellites). If you can get one to work properly, more power to you. If you can 'signal lock' the WB68 with yet more equipment, same. But when you get problems, toss the junk and go with the 616; more $ but no hassle. That's the bottom line.

I've had long discussions with both DirecTV engineers and their contract installer/engineers, and the basic reason they still use the WB68 is simply cost. If DirecTV gives it out for free, kinda get a clue. But keep a close eye on it, and if/when you start seeing wacky problems, toss it out.]

When I had my dish & HD receiver installed, I told them I have more than 8 drops and that I would need a multiswitch(s). They provided them FREE of charge. I only had them wire in the one DVR and I did the rest because I wanted to cables neatly routed and not stapled across the floor, baseboard or ceiling.

I have not experienced any issue with the Zinwell WB68 however, I just had the HD DRV replaced with a refurbished unit just 9 days after the original "NEW" HD DVR was installed.

Do the 4 cables between the dish and the WB68 have to go between certain connections on the dish to certain connections on the WB68, or do you just connect the 4 wires to any of the 18V & 13V connections?

HondoHDTV 03-30-2007 08:33 PM


I didn't find that to be an issue... the only concern would be is if you are splitting the signal to feed "TWO" zinwells... then the outputs from the splitter must match the input to the zinwell(s) as shown in the diagram.

since all 4 outputs on the LNB can do 18 and 13 plus both voltages with tone it does not matter what line goes where

the LNB will figure out what it is connected too and lock to the voltage or voltage and tone.

When using 2 Zinwell's, what do you reccomend for splitters? Brand?

lunchbox902 04-27-2007 07:17 AM

the splitter must be power passing and be rated to pass 250 MHz - 2150 MHz. the brand i use most often is jvi #25-hfs22dn and they are rated for 5-2300MHz

It has to say all ports power pass to work.
