    I cut the cord a while ago and have an outside antenna that gets very good reception. I am going to be replacing an older desktop system and, since I am replacing the desktop anyway, I am looking into what I would need to add DVR functionality. I pretty much know what I need for hardware to make sure that the system can capture video but I do not know what I would need to network it with my TV to watch the captured video
    The TV is a Visio M75-C1 with 802.11ac Dual Band WiFi. The house is a two story. The antenna cable runs across the attic, through the opposite outside wall, down to where it enters the cellar and then up to a wall plate in the first floor living room. It is a total length of about 80 feet of quad-shielded copper RG6 with compression fittings. The desktop is on the the second floor in the same room as the cable modem. Here is what I need help on:

    • The easiest way to connect the desktop to the antenna is to split the cable in the attic and run a leg down to the desktop. The split will happen about 25' from the antenna, the desktop leg will be about 20 feet. Will splitting the cable degrade reception? Is there a better way to do this? What should I look for in a splitter?
    • Once I can capture video how do I stream to the TV? I could run HDMI cable from the desktop to the TV but that would be a pain and expensive I have no good way to get a cable to the TV wihout running outside and following the route of the antenna cable to the TV. That is to long a run anyway for HDMI. Is it possible to wirelessly stream video to the TV? The TV has 802.11ac Dual Band WiFi. If I have to run cable what type of cable should I use fo the best video quality?
    • Aside from the hardware, what else do I need to consider?
    Thanks for any help.

    There are two ways to go. 1) by a premade DVR or 2) build your own DVR.
    1) premade. There are really only 2 to choose from that are any good. a) TiVo and b) Channel master.

    a) TiVo https://www.tivo.com/ is cheap to buy charges a monthly subscription that is insane, you might as well get cable and rent a dvr.
    b) Channel master http://www.channelmaster.com/DVR_Plus_p/cm-7500gb16.htm is expensive but has no subscription cost.

    2) Build your own. The only real DIY DVR system out there is MythTV https://www.mythtv.org/
    Essentually you build a (not insignificant) Linux box to act as a DVR. Because it is DIY, you make all the decisions but if you are a networking/software/hardware novice, this is not the right choice.

    As to how you connect it? An ethernet cable in all cases. In case 1) the product comes with good-enough instructions. In case 2) there is youtube to guide you. :)

    P.S. I went with option 2). I'm still not done. And I'm not a novice.

    I have several different DYI DVR's, and now I use my smart TV to be the center point. I have been using OTA only for quite awhile, and with the savings, I purchased my smart TV. I am going to show you my video of my smart TV as the center point of my Cord Cutting adventure. I have one DVR (not shown in this video) that only uses one $30 Android stick running LivreELEC and an HDHomeRun tuner for my DVR backend.

    Here is my latest update on my cord cutting.
