    • Amazing little box!
I had an Internet/TV/Phone bundle through Verizon that I've had for years but I finally decided to "cut the cord" because I was tired of paying for TV service that, honestly, I rarely used. We have a couple of streaming services that we watch purposefully, and we only ever used the TV service for background noise or to watch live TV during special events or local news or things like that. So I dropped the bundle, increased my Internet speed, and ended up cutting my Verizon bill almost in half. As part of that decision, I decided to get this HDHomeRun box so that I could still get local broadcast stations for local live news and event coverage. I paired it with this antenna: https://a.co/d/4Xrc74l The box is in my basement, connected to my core switch. The antenna is on the second floor of my house near a window. I reused some coax I had in my house to connect the two - making sure that nothing else was connected to the coax - no splits or anything. This box is great. My Plex server found it immediately and was able to perform a channel scan and pull guide information no problem. AND even though I'm using it with Plex, you don't have to. As long as you have a device on the same network at the HDHomeRun box with the HDHomeRun app installed, those devices can address the box directly without needing to go through Plex at all. I was hesitant to buy a box with four tuners in it - why would I need four tuners? I discovered the answer during the eclipse on April 8 - I had Plex set to record two different news broadcasts during the eclipse while I watched a third broadcast using the HDHomeRun app on my Chromecast with Google TV. This engaged three of the four tuners in the box, and it performed perfectly. I will point out - since some of the literature is unclear - that all four tuners are capable of ATSC 1.0, but only two tuners are capable of ATSC 3.0. In my area, only two channels are broadcasting in ATSC 3.0 right now, but even those channels are broadcasting in both for the time-being. But for most folks, ATSC 1.0 is all you need at the moment, and having four tuners that can pick that up really makes it useful when you want to watch or record multiple things at the same time. Set up is easy - plug the box into your network. It will check for firmware updates on its own, and you can use the web interface to apply those updates if you wish. I gather that it essentially uses DLNA to share the media streams, so anything on the same network can use the box. Also, if you're using it with Plex, the recommendation is to assign a static DHCP lease to the box because if the address changes, Plex may have to set it up all over again. This is not a requirement if you're just going to use the HDHomeRun app, since the app looks for the box via broadcast each time you open it. This box is easy to use, works with a wide variety of devices and applications, and is practically plug-and-play in terms of setup. I am very pleased to have it. ... show more

I’ve been a Silicon Dust HDHomeRun fan for quite a few years. I bought a HDHomrRun PRIME nine years ago to try leveraging my home network for TV distribution. Shortly after that I sent my cable box packing and relied only on the HDHomeRun along with Plex to pickup DVR duties. I did try out the HDHomeRun DVR when it first came out, even using the Kickstarter to get early access to it. However, in the end, I preferred the ease of use of Plex. Over the next few years, I found that I was watching less and less TV, for a number of reasons. I scaled back my service to the point that I was eventually just getting the local channels. All I was using it for was the local news and an occasional show like American Ninja Warrior. It was becoming harder and harder to justify the cost. It was about $30/month plus another $6/month for the cable card as part of a TV and Internet bundle. Fast forward to early 2023. While doing some tech upgrades in the house I found that I had an easy way to get a coax connection from my basement, where my entertainment center and most cable endpoints are, up to the attic. I decided to take the plunge, install an antenna in the attic, and then swap my HDHomeRun PRIME for a HDHomeRun FLEX 4K. Best decision ever! The antenna I put in the attic is an Antennas Direct ClearStream 4V. This is a big antenna designed to pull in stations from a long way away. As it is, I’m only about five miles from the Washington DC stations, so this antenna was overkill. I didn’t want to take any chances being that the antenna would be in an attic and the house across the street from me, in the direction of the transmission towers, is about twice as tall as my home. The antenna more than handled the situation and even picked up some stations I was not expecting, from Baltimore, that were not even in the beam width for how I had the antenna aimed. Now, we get to the HDHomeRun. When I hooked it up, is spotted 90 channels! A few of them seem to be ghosts as they report a signal with no content. Of the 90, I could tune in 82 of the channels. Plex had a few more issues and only knew about 67 of the channels, but it got the ones I cared about along with dozens I really didn’t care about. For my usage, I could have got away with a HDHomeRun DUO, two tuners being one more than I typically need on a given day. However, I’m trying to future proof and wanted to be ready for ATSC 3.0 (aka, NextGen TV). The DC area is fortunate to have ATSC 3.0 signals for all the major networks. The FLEX had no trouble receiving these signals. I’ve been able to fire up all four tuners at once using a combination of a computer, a phone, a tablet, and a Chromecast with Google TV. The HDHomeRun app runs on all of them. The app isn’t perfect, but it works. The only thing I would ask for in the app is the ability to get technical details on the stream. The only way I’ve found to get that is to go to the web interface for the HDHomeRun and look at the tuner status. Only two of the tuners support ATSC 3.0. That is good enough for a first generation product, especially since the ATSC 3.0 stations are only simulcasting the regular broadcast at this point. The FLEX 4K is smart enough to give preference to the non ATSC 3.0 tuners when tuning in an ATSC 1.0 signal, to keep the 3.0 tuners available if you need them. As for handling the signals it receives, the FLEX does a great job. For the local stations, the image is rock solid all the time. The interface shows 100% across the board, so I would expect no less. The Baltimore stations were the biggest surprise. The ones I receive, come in about 56% power but the symbol quality still shows as 100% and the image has been stable for them as well. Oddly, there are some stations that are on the same towers as the ones I get that don’t come in at all. WBAL, the NBC affiliate, is one of those. It is as if it isn’t even there. I don’t really care about the Baltimore stations, but this did leave my scratching my head. No product is perfect, and there are a few things I think could be done a little bit better. The biggest one would be to send the signal from a single tuner to multiple destinations. If two users tune in the same station, it still takes up two of the four tuners. With four tuners available, this won’t likely be an issue but it would be more efficient. The only other thing I don’t like about the FLEX 4K is the total lack of indicator lights. It is truly a black box and the only way to check the status on it is through the web interface. For contrast, my PRIME has a power light, cable connectivity light, and a separate light for each of the three tuners that come on when in use. You know what is going on with that box with a single glance. To wrap it up, my HDHomeRun PRIME will be looking for a new home. My cable provider has lost a video customer, although I did up my Internet speed with some of the savings. I’m receiving more stations than I did via cable and can watch them anywhere in the house via either the HDHomeRun app or Plex’s Live TV feature. Hopefully the HDHomeRun FLEX 4K will get to flex its muscle on some 4K content once the local broadcasters start providing it. Even while waiting for the next generation of TV, add me to the cord cutters club. ... show more
