Will a multiswitch work for me?

    I have an older oval directv satellite dish that gets HD signals. It is not the new kind where everything streams from 1 box. In fact I have 4 owned hr24 receivers hooked up to it. I need twice as many lines so I can record on one channel and watch a different one, can I use a multiswitch for that? 2 lines are close to each other in the garage and 2 more are close in the attack. If I could add a multiswitch in both of those locations to double the number of lines I have I would in great shape. Is this possible?


    Thanks in advance for the help!

    You should be able to add a SWM8 multiswitch and then run only one line to each receiver. This would allow you to record one channel and watch another on all 4 DVRs.

    It's a fairly easy upgrade if you are comfortable with going up to the dish and can make your own coax lines (or are prepared to buy 4 cables to go from the dish to the multiswitch.)

    No;

    A legacy multi-line multiswitch for HD needs all four lines from the dish as inputs to provide HD service. Two lines at each location is not sufficient.

    As Stuart says your best option is to convert to SWiM and install a SWiM-8 multiswitch somewhere near the dish then run four short lines from the dish into it. Then run either a single output from the SWiM-8 through a 4-way SWiM splitter to the current four coax runs you have. Or the two outputs of the SWiM-8 can be used to feed two 2-way splitters and then the four coax runs for the the result.

    A PI (Power Inserter) must be properly installed somewhere indoors near an AC outlet on the coax run connected to the power passing port of the splitter that connects to output leg 1 of the SWiM-8.

    Unless by "older oval dish that gets HD" the TS means a first generation ODU, the AT-9;

    then he can't simply upgrade the LNB to a SWiM type.

    I forget the reason I did not upgrade when I purchased the HR24's (they are owned) and I really don't want to reread everything just to find out (and possibly not find out). I'd rather just run the wires the hardware.

    I have a slimline, like most of you guessed. Why does the multiswitch have 6 inputs? Does it need 6? I'm pretty sure my dish only has 4 lines coming from the LNBs.

    Will this multiswitch reduce quality any?

    Thanks a lot!

    Two of the inputs are "flex ports", that are/were used for the 95 SAT along with the [now not used] 72 SAT.

    If you use the WB68 multiswitch in your link, you will need to run all 4 wires from the dish to the switch and then you can run two wires from the switch to each of your DVR's. You can NOT use two WB68 switches together. Nor can you put splitters on on the lines that you have. A WB68 setup requires two home runs from the switch to the DVR's.

    As others have pointed out, going with a SWM based system will be much easier for you to install.

    Also if you install the 6x8 switch, you would need BBCs for the HR24 HDDVRs

    Well actually you can use two WB68s, but you have to do it right. The four lines from the dish must go to dual port power passing splitters, then the outputs of the splitters have to go to the same input port on each of the WB68's. If your coax lines are not too long, this should work. If you are dealing with fairly long coax runs, then you might also want to add a Sonora phase locker/power inserter between the LNB and the four splitters.

    What you can't do (or perhaps more accurately what you shouldn't do) is to stack the WB68s where four of the outputs of one feed the inputs of the second one. That can lead to problems.

    He should already be using BBC's.

    I was able to convert an AT-9 to and ODU 5S. I thought I wrote a first look about it. I'll have to dig that out of the archives.

    EDIT: Here's the link to the forum thread, but the link is broken. I have asked Stuart to fix the link in the post: http://www.dbstalk.com/showthread.php?p=1613603#post1613603

    Oh yea, sure;

    But except for the 2" OD mast, you have to change out the entire ODU assembly.

    What I was referring to though was that you can't simply upgrade the LNB of an old AT-9 to an SL5S.

    Of course its all irrelevant now since by "the older HD dish" the TS did not mean an AT-9, but a SlimLine 5 with a legacy 4 output LNB.

    I should have been clearer. The OP can't use 2 WB68's in the manner in which he was asking about, where he wanted to run 2 lines from the dish to one WB68 and the other two lines from the dish to the other WB68.
