    I just ordered a zinwell 4x8 multiswitch for $30 plus $10 shipping at Ebay. The seller has 19 still available at the link below:

    Ten dollars for shipping! I've never bought anything from Ebay but I'm thinking of selling my S/A. If someone can charge Ten Dollars for a multiswitch; I'm getting carried away here . Truly sorry

    re: The Zinwell SAM-4803 4x8 multiswitch...

    I installed one of these last week, and it works fine. However, it runs very hot (the unit and the power supply).

    Is this normal?

    Thanks,
    Jeff

    High shipping charges help some retailers to undercut the competition on the quoted price and get listed first. You see it at all the shopping sites.

    Many Ebay sellers use high shipping to ensure they get a minimum price in case the bidding is lower than desired. It seems that the items with high shipping always go for lower prices. Self-fullfilling prophecy?

    I just look at the total price and compare.

    Can the triple LNB with integrated switch be used on the channel master dishes?

    Just for reference in case anyone is searching for "USTec" and "triple LNB" (like I did)... Note that this note may not be applicable to the CX-DSS58.

    My house has a USTec CX-HDA58 multiswitch/8-way OTA antenna splitter. Yesterday I installed a triple LNB DirecTV dish and HR10-250 DVR.

    This was a self-install, so as others have noted, if you get an installation from DirecTV they will most likely just bypass your built-in multiswitch with one the installer brings. Previously, after our first SD DVR was installed using the older single LNB dish, the installer had cascaded two 3x4 multiswitches to connect all of our receivers. This was a cabling mess, so I wanted to utilize the built-in equipment if possible.

    The 3rd and 4th LNB connections on the CX-HDA58 require 22 kHz tone generators. I ordered them from hometech. Search for P/N CV-22T. At the time of this posting they are $13 each. A bit cheaper than a new 4x8 multiswitch, and it is a much cleaner solution since all of the hardware and cabing is built into the USTec cabinet. I have 4 DirecTV receivers (HD DVR w/2 satellite drops, SD DVR w/2 satellite drops, and two SD receivers each w/1 satellite drop) and they all work fine (seeing all 3 satellites).

    Note: due to the angled placement of the multiswitch in the USTec cabinet, I had to make a short RG6 cable (4") to connect the LNB 4 tone generator. The CV-22T has a male connector on the multiswitch end, designed to screw directly to the multiswitch. The CX-HDA58 LNB 4 connection is too close to the wall of the structured wiring cabinet for the tone generator to directly screw into the connector.

    Note that the newer MPEG-4 DirecTV AT9 dishes are only guaranteed to be compatible with the Zinwell WB68 multiswitch. So if and when I upgrade to the MPEG-4 HD system, I may have to abandon use of the USTec built-in hardware.

    i've installed several of those zinwell(4x8) and yes they do get very hot
    just remember you have lots of current going through that switch
    so if your not having pixel problems your in good shape

    I realize this is an old post - but I have this issue - I just got a D* 3 LNB with built in MS. I want to use just 2 RG6 cables from the dish into my house. Once inside I need a MS for my two SD TIVO's. (NOTE: I'm replacing a 18" Dual LNB)

    Would it be possible for you to provide me with the details of the MS that you used???
    Also - did you need to do anything "Special" at the dish??
    Thanks --- Bill

    Not sure why you are doing this. If you want to use a Phase III oval dish with only two cables to the house, it will behave exactly the same as the old 18in dish - receive the same satellites etc. So what's the point?

    Anyway, if you connect the two cables to any standard DirecTV multiswitch (2x4, 2x8 or even a 4x8) it will give you enough outputs to connect four cables to the two TiVos. But as I said - why?

    Why? Money. Maybe he doesn't have any to buy a newer model.

    But he does not need a newer model....the 18in dish would still do what he wants...
