    I don't think DirecTV has another option available for their customers. I'm actually on hold with them right now trying to find out an option.

    What some people have been doing is installing splitters between the satellite and two WB68 multiswitches. others have reported cascading a 4x8 multiswitch off the WB68 multiswitch works too, but only gives you 4 HD MPEG4 lines, but you can run your older recievers off the 8 outputs of the 4x8. But not sure if cascading the 4x8 actually works - never tried it.

    Update: The only option technically DirecTV apparently has is to install two AT9 dishes. I got them to promise me a credit for the cost of the new WB616 6x16 multiswitch when I get one though instead and I'll keep my tripple LNB Dish up and they'll put up a second dish, the AT9. My house will run on two dishes until I get the 6x16 when it comes out in the months comming up.

    The installer should install a WB616 which is the new powered Zinwell switch. You should contact DirecTV and make sure the installer brings that multiswitch - call the installer directly if you can, otherwise he will show up and will not be able to get things to work. Cascading two WB68s almost always will not work.
    You can use two WB68s driven by the outputs from four broadband power passing splitters as has been posted here but a WB616 would be a better choice.

    Cascading a WB68 with a cascadable 4x8 (5x8) works fine (you take four outputs from the WB68 and connect them to the four inputs of the 4x8) except anything connected to the 4x8 will not get any of the new satellites. If you cascade to a 3x8 multiswitch then anything connected to that will not see MPEG-2 HD or the new satellites.

    Thanks for the info...DTV said the installer should be contacting me in the next 24 hours...when that doesn't happen, I will call back tomorrow and ask that a WB616 be brought and swapped out for the WB68 since I need more than 8 lines and want them all to be HD...I am sure what will wind up happening is either the splitter thing or casading to a smalled switch since I only have the 1 HD receiver...but whatever, so long as all of my tvs work as they are currently setup...ill be somewhat happy...hopefully I can get it working though so that all 10 lines work and get HD (for future upgrades!)

    I was just told the WB616 isn't available for DirecTV to send out with their installers yet.... Solid Signal also told me they can't get them for 2-4 weeks.... Where are they getting them now?

    My installer came by yesterday to double check my dish signals for me. He promised that he is going to get a wb616 for me as soon as he has them available. he also gave me his cell phone so if i have anymore problems, i can call him directly.

    I just call ZinWel, the DB616 is $250 Plus shipping right now. I think I'll wait for it to become avaialble in Nov when it starts shipping.

    Albert - cascading a 4x8 (or a 5x8 - mine is a Terk) from the WB68 works fine. It gives you four lines capable of supporting the new satellites (for the H20 or HR20) , and eight which only support the three old ones, for any older receivers including the HR10.
    Using four broadband all-port-power-passing splitters to drive two WB68s works fine too (see the post from steelr). Gives you sixteen lines capable of supporting the new satellites.

    So...DirecTV came out today to fix my issue of only have 8 of my 10 lines plugged in. Showed up unannounced which made my wife who was home with our 1 year old daughter quite scared. I happened to be on the phone with her when they showed up, so I talked to the guy to explain the problem...

    Told them I had 2 3x8s cascaded and 11 lines coming in and was left with 1 6x8 and 3 lines unconnected. Said that I wasn't sure what they could do because I was told you can't cascade the 6x8 multiswitches. He didn't have a 6x16, but said he realized the cascading limitation and would stack two 6x8s multiswitches...

    Any idea what "stack" would mean in this scenario. The guy seemed knowledgable. Is there where they take the 4 splitters and split out my main 4 lines so that each goes to serpate multiswitches leaving me with 16 outputs or something else? I'll obviously know when I get home and see what he did, but I am curious if people here think based on that terminology if it was done correctly...

    Thanks,

    Definitely not what they did! They simply cascased them so I have 12 outputs. I have read all over this forum that cascading won't work, but all 4 DVR/TIVO receivers including the HD DVR work as expected...
    When/Where would I see issues?

    On the local HD channels on the cascaded switch (supposedly).

    If you cascade two Zinwell 6x8 it can work sometimes but usually does not. Because the WB68s are non-powered the switching voltage from the receivers has to pass through two multiswitches before it gets to the multiswitch in the dish. In most installations the combination of the switches and the cables drops the voltage too much for the system to work.
    Some installations with short cable runs and with certain combinations of receivers appear to work. Others lose one half of the transponders on the 119 satellite. If yours is working that's good but I would not trust it to continue to work, just a slight change in the characteristics of your system (e.g. a connection that deteriorates slightly) could decrease the switching voltage below the operating level. The manufacturer says the switch is not cascadable and in most installations that's true.
    The correct way to drive two WB68s is to use broadband splitters with power passing on both legs as has been described earlier.

    Thanks for the info...I think DTV is sick of hearing from me, and right now everything is working...maybe they ran my HD lines from the first switch, not the cascaded one, so it works and since the others are just SD DVR/Tivo receivers it doesnt really matter to them...

    If I ever upgrade and get more HD TVs and then see an issue, I guess they can come out then and fix everything, or thats even something that I can probably do myself...

    so long as its working, that's all I really care about it...

    I placed my order with directv today for 3 HR20s!
    I currently have 2 HR10-250s and a sdtivo in the living room

    2 HR20s will be added to the living room
    1 HR20 added to the bedroom
    1 H20 already in office upstairs

    The way I have it set up now is a 5x8 outside and a 4x8 in the living room for those 3 dvrs soon to be 4.

    Will 2 WB68s work and cascade? ***IF I need to order a power block inserter I will to be ready for Mastec Installers **Advanced Technologies**

    My 2 exisiting switches are both powered.

    I realize i will lost the ota diplex for now until SWMs are available for deployment in the field to consumers.

    I have on my notes that a WB616 or 2 WB68s will be required to complete installation and if I am charged in anyway, directv will credit me. Ive called back and asked two different reps to read that note back to me.

    Mastec is calling me tomorrow **Lead tech** to get everything straight and ordered if nessecary to complete successful install.

    Since you cant diplex with WB68 or WB616 I have reserved 1 line in bedroom and 1 line in living room, and 1 line upstairs for OTA only.

    This will require , assuming mastec doesnt have to run new lines to the living room. 1 new line to bedroom for second tuner ( I have 2 total there now, 1 will be used for OTA) and somehow have to have 8 lines in living room. Dont care how they do it , just that it is done and done right.

    I have, at directv high recommendation contacted mastech to fill them in and set the expectation for them weeks in advance so that this install will flow as smooth as possible.

    My main concerns are the power inserters, the cascading WB68s.

    If they have to install WB616 they will be running lots of new lines i think.

    Perhaps if they dont have the power inserters they will install a WB616 and a WB68..Not sure.

    Im excited about my new HR20s coming though, Mits 73833 and vizio 32...all new toys.

    Looks like Mastec has cleaned up their act lately. Just got a call stating that they will be bringing the following with them

    After discussion of the exisiting setup , Mastec supervisor stated they will bring a WB616 and a WB68 for cascadable installation. The Lead tech has been locked for the 22nd install. Im getting excited!. Mastec said they will make sure their installer gets paid for the multiswitches and not to worry about it. Also asked if there would have to be any wallfishes and I said that all of the rooms requiring additional lines would be accessable from the exterior. He said they like to make it look professional and might do a site inspection before the 22nd just to look at some of the rooms.

    We then talked of SWMs and he said I wish they would hurry the #$*&() up as it will make their jobs 1000 times easier.

    I found this website by using the DirecTV forum.
    I just had a new 5LNB dish installed and a HR20-700. To make it short its not working properly. Sat 110 has no signal so I only get half the HD channels. A tech is coming out on Saturday but wanted to ask your input.

    Do I really need a Multiswitch for my setup?
    This is my old setup.
    3 LNB Dish
    4 lines coming out of it.
    2 lines to living room for Tivo R10
    2 other lines to two bedrooms for just regular recievers.

    New current setup.
    5 LNB Dish
    same 4 lines connected to new dish.
    2 lines going to new HR20-700
    2 other lines to two bedrooms.
    The only change in 1 bedroom is the Tivo R10 got moved over, will be using only 1 tuner though.

    So i did a multiswitch?
    Thank you.

    As long as you are happy to stay with one tuner on the R10, you do not need a multiswitch. The 5-LNB has four outputs, so can feed up to four separate tuners simultaneously. Two tuners in the HR20, one in the R10, and one in the regular receiver. Total four. Good to go.

    If you want to add a second line to the R10, then you need to add a multiswitch. Four coax from dish to multiswitch, then from multiswitch to each receiver one or two as applicable.

    The 110 problem is likely to be either a bad LNB, or bad alignment. But if you are getting 101 and 119, then alignment is probably okay.

    It seems to me that the key to cascading two 6x8s would be to have 4 receiver lines hooked to the outputs of the multiswitch that is connected directly to the sat outputs, that way you've got at least two receivers powering the first multiswitch and the LNBs, and any additional receivers hooked to the cascaded multiswitch don't have to be responsible for passing their power through two multiswiches in order to power the LNBs.

    I tried cascading my 2x8 off my Zinwell 6x8 to see if it would work for when I add a 5th DVR and will need 10 outputs (6 of which will only need to see the 101 sat) , and it worked fine.

    That wo't necessarily get you what you want. What you really need it the four different voltage/tone combinations to always be present on the feeds to the dish (inputs to the multiswitch). The only way to do that is to either (a) use a power inserter between the dish and first multiswitch or (b) use a powered multiswitch cascaded off the first WB68 (so that all 4 combinations are always requested via the powered multiswtich).

    The only reason to select option (b) is if you already have a powered multiswitch and want to use it to feed non-HD receivers. For example, at one time I hung a Terk BMS58 onto the first four output ports of my WB68 - it provides the power and tone combinations. I used the remaining four outputs of the WB68 to feed mpeg4 receivers, and the Terk to feed all the legacy stuff.

    But you don't need all 4 voltage/tone combos to be present at all times. If you have a single unpowered 6x8 and all the tuners hooked up to the outputs are tuned to a channel that only sends 13v up the line, everything still works. It seems that 13v is enough to power the multiswitch and the LNBs and that the extra 3 volts on some of the lines is only required as a signal to select the correct sat and/or polarization, but not necessary needed to supply power to either the multiswitches or the LNBs. I think that the potential problem is if no receiver is supplying either voltage to the first multiswitch that is hooked directly to the sat and a single receiver hooked up to the cascaded multiswitch has to power both multiswitches and the LNBs at the disk.
