    Does the dish itself need to be grounded? It's mounted on my roof and runs to the side of the house to the telephone box. If I get them to properly ground the cable at the junction point, will this be sufficient?

    Sorry for so many questions...


    Generally, they will use a cable from the dish that has a ground wire built into it. When it gets to where the cable goes into the house and they use a barrel connector, the tech will usually ground it at that point using that ground wire. As long as the the dish is grounded in some way, you should be fine, although I believe DirecTV has certain specifications as to how the ground is performed.

    I found that wire (neat!), but the ground portion of it has been cut

    Yeah, you're not grounded then.

    Yep Merg I forgot about the coax with the ground wire built in. Some installers do not use it and do it the other way.

    My installer seems to have bypassed it all

    They're coming out tomorrow to fix the sloppy install... We'll see how it goes

    So a new tech came out today and here are the results

    Amazing what 5 minutes can do! I'm happy with it overall and might through a few additional zip ties just because I'm super picky about wires

    If anyone sees any issues with the way he did it, please let me know. To my novice eyes, all looks good now

    I can't really tell from the angle but is there a terminator or just a cap on the unused port on the splitter?

    Well not "totally" good I'm afraid;

    There should be a 75 ohm terminating cap on the final output of the 4-way splitter.

    But the rest looks fine.

    And I probably would have had drip loops on the cables coming out of the splitter...

    The only thing I would add are plastic tags to the 3 leads entering your home. That can save a lot of time later on.

    All that is on there is a plastic cap. If I do not have a 75 ohm terminating cap, what issues will arise?

    Are the drip loops solely for collecting water and condensation and "dripping" it away from the splitter?

    Also, there is not a lot of slack on the coax there. What can be done if a drip loop is needed?

    The tech said something today that he left a drip loop coming off the bottom left where the 3 coax are. Guess this is a rigged drip loop?

    I think is worse than before! That splitter should be sideways so water do not get in to the cable feeding the splitter. also the ground block has a cable coming in with no drip loop and a perfect angle for water to run in. this should be taken care ASAP or sing up for the PP to get those fittings change frequently!

    Ugh

    I can rotate the splitter, but I don't think there is enough slack to make a proper drip loop

    This is what a drip loop should look like...

    [​IMG]

    Basically, when water runs down a cable, it will follow the cable even if the cable bends and it can actually go upwards somewhat as well. The drip loops make it so that the water is forced to drip off of the cable and cannot follow the cable to its connection point.

    Signal reflections from the un-terminated ports can cause issues with degradation of the network signal at the receivers.



    The thing is since the MoCA 1.1 standard was designed for robustness in the face of wide varying degrees of multipath and signal reflections typical on a customer's coax plant, you likely will not even notice it.

    But it is still good practice to properly terminate all unused signal ports anyhow, through admittedly there's no major urgency to get it capped.

    You can raise the spitter and turn it sideways and that will fix that. my question is, why is that ground block there, it is obviously not being used as such but rather being used as a mountable barrel connector. how many receivers do you have? can that cable be connected to the splitter?

    this is a bad example (loop on the left) as the cable coming down passes just by the connecting points and water will "jump" to those connectors . Loop on the right is to straight and with the nail clips will not let water run away
