    My upgrade for LIL is scheduled for Dec 15th. The pole is installed..but thinking
    of putting in conduit as the ground may or may not be to hard to dig
    mid Dec when the installer gets here..
    What are the pro and cons of conduit for RG 6?
    Any advice is appreciated...

    Also the tech who did line of site today recommended mounting the multiswitch outside on the house. Is that ok to do?

    I used conduit on my third round of digging up my buried coax.
    "plus" is you can pull more coax if needed.
    If you do this, leave a string for him to pull the coax with.

    Switches are made for external mounting, "but" try to shelter them from direct rain, etc.

    another plus to conduit is you dont chew it up with the weedwacker

    advice would be to run the coduit up a ft or so at the pole and at the house. for making the 2 turns get rounded sweeps not the 90 degree turns. put string thru as VOS said.

    as far as where to mount switch they made for outside but inside is always best to me.

    :confused: If you're needing to run 150', you're getting close to the limit of a legacy system [without using amps]. I don't see any difference if the switch is 50' or 100'. or more as with a legacy system, the power comes from the receivers at the far end.
    If you're going with a SWiM, then there is sense having it within ~ 45'.

    I thought it was a long run as well.. he said no problem. He said I would have 200 ft from the multiswitch..

    If you're getting one receiver/DVR, they still use legacy.
    If you're getting SWiM, 200' is the limit for using "just" a 4-way splitter.

    I am getting 2 HD DVR's.. right now I have a round dish and 2 SD DVR's.
    1 multiswitch in basement..

    I did some measurements going to be around 150 feet from dish for 1 DVR, just a little over 150 for the second DVR.. maybe 153 or so..
    Guy who did line of site said it would be fine...

    if you only use a 2-way splitter, you'll also gain some reserve.

    You've got about 30 dB of loss to play with before you get into problems.

    150' is about 12 dB at the last frequency you'll be using.

    an 8-way will add another 14 dB, a 4-way only another 10 dB, and a 2-way would be down to 5 dB.

    To some degree rainfade can be reduced by having more "reserve" in your system, so 17 dB might be better than 28 dB during heavy rain.

    With 2 DVRs, it would seem you'll get a SWiMLNB.
    Single coax from dish to house. PI to power the SWiM, and the either a 4-way or 2-way off the PI and a coax to each receiver/DVR.
    The splitter can be before the PI and the PI can have a receiver connected to it.

    [see my addition to the above reply]

    Trying to figure out why he told be since I have 2 wires running from my small dish into the house now that he would mount a multi switch outside and connect it to the wires already running into the house for the slimline

    I don't know what he is/was thinking. If you don't get a SWiM, then you need four coax to a multiswitch for all the HD channels. If you get a SWiMLNB [which is the most likely] there is only one coax output.
    Mounting a SWM8 at/near the dish could end up using two coax, but isn't needed.

    No. There are two dish techonologies. SWM which requires one coax from the dish to feed all of your equipment (up to 8 tuners), and legacy which for HD requires four coax from the dish. With legacy, you need two coax to a DVR in order to have two tuner functionality.

    With two DVRs and a legacy dish, you would run two of the coax from the dish to one of the DVRs, and the other two coax to the second DVR. No need for a multiswitch at all.

    So really for me SWM makes the most sense..
