Review: Excelente opción para no pagar televisión por cable - A nadie le gusta pagar suscripciónes, y en este momento de la vida, en el gran año 2025, todo el mundo quiere cobrarte dinero: Disney, Netflix, Televisa, TV Azteca; todos. Pero la realidad es que pocas suscripciones valen la pena. ¿La televisión privada? 100% no lo vale. Algunos te dicen que 4K, otros que HD, otros que todos los canales del mundo. La realidad es que, pagar de más por un producto completamente inferior (hablando específicamente de los que ofrecen 4K) a lo que encontramos gratis con una antena en el techo, es un robo. Entra el HDHomeRun. Lo que unos te ofrecen via IPTV a 720p30 con sonido 2.0, recíbelo a través de tu antena aérea a 1080i60 5.1, no sólo en tu tele, en cualquier dispositivo compatible con la aplicación (Lo probé en smartphones, tabletas, laptops, y Smart TVs), y notarás, no sólo mejor resolución, sino mejor calidad de imagen. Un producto que definitivamente no es para todos, pero si como yo, eres de los que se interesan en recibir la mejor calidad de imagen y audio de la televisión abierta, no puedes dejar pasar la oportunidad de adquirir este sintonizador,
Review: Good Unit - So far, we are quite pleased with this unit. We've had it working for about a month now. The HDHomeRun unit sits beside our wife router, and is attached to an antenna in the attic. I have a portable USB HDD hard drive attached to the unit by a short USB cable. I thought 500 GB would be plenty, but we go through it pretty quickly over the course of a couple of weeks. It keeps me disciplined to delete stuff we won't go back to, but if I was doing it again, I would get a 1 TB drive. We purchased the annual guide subscription ($35 US) - totally worth it to see what is coming up over the next few weeks and to record what we want. The HDHomeRun app is loaded on each Fire Stick for each TV in the house and on my computer, so live and recorded TV is available to all TVs and computers, and recordings can be managed from any device. It works perfectly - does everything we were hoping for. Our only complaint is that the home screen navigation is a bit clumsy - especially getting between the channel bar and the menu bar with our Fire Stick remote - and the bottom menu is tiny. We got used to it quickly enough and its not a big deal. Overall, it's a great little unit that gets free network TV and let's us skip through commercials on recorded programs. Highly recommend.

## Questions & Answers

**Q: Says "requires paid tv guide for dvr record", so all recording is totally disabled unless you pay?**
A: Just received my order.  Attached and it formatted USB drive.  Even though the app allows me to setup to record shows, no recording was performed.  Under Account Info, showed DVR is not active.  After googling, HDHomeRun's web page said subscription ($35/yr) is required if want to use DVR on HDHomeRun ("not required if you are using third party DVR software/service" like Plex).

**Q: Router in garage, indoor antenna best by far away window, no ethernet ports in house, coax outlet only. Can I make this unit work?**
A: I don't know how you'd do that without an Ethernet connection.  This is designed to take "off air" programs by way of an antenna and provide them on an Ethernet connection so that you can either control them with a server (which is often acting as a DVR), or with a network direct connect to your streaming box or Smart TV.   If you're running your network using Wi-Fi for streaming, and you have an Ethernet connection in your garage on your router, you could plug it in there.  Long coax runs from an antenna can exhibit loss, so it's difficult to assess how well that would work since I'm not actually there, I can't comment.  If you can get good TV signals off coax in the garage, then it should be able to work through your router.

**Q: Can you record two channels while watching a recorded show?**
A: Yes, you can record two channels while watching a recorded show. Recording requires a USB hard drive and TV guide ($35/year).

**Q: I have an 8k av receiver w hdmi 2.1. i want uncompressed ota tv with a guide. no need to record/stream. prefer no atsc 3. what are options?**
A: Any SiliconDust tuner.
