About this item

Product details

Receive Free to air TV via an antenna allowing you to send glorious high definition content to anywhere in your home over WiFi, or a wired Ethernet connection from your own existing home router. No more expensive Cable TV subscriptions or cable box rental fees. Please check the RabbitEars website to see if the ATSC 3.0 channels in your area show a padlock icon indicating that they are DRM encrypted. ATSC 3.0 channels that are DRM encrypted will not work. DRM encryption is used by select broadcasters to block out-of-home viewing, limit what player devices can be used to watch TV, enforce that the original tuner hardware is always present to view recordings, and to block third party apps. Optionally a broadcaster can force recordings to expire after a period of time and/or block recording completely. If all ATSC 3.0 channels in your area are DRM encrypted you can use any HDHomeRun FLEX model to receive channels using ATSC 1.0.

Excellent Device, Easy Setup and Great Flexibility

I purchased the HDHomeRun FLEX 4K as part of my transition from cable style streaming television to over the air reception, and I've been extremely pleased with it. Setup couldn't have been much easier. I connected it to my antenna and home network, and it was working almost immediately. The HDHomeRun app is straightforward and easy to navigate, and the viewing experience has been excellent, with no issues I've been able to attribute to the device. One of the biggest advantages is having four tuners available to devices throughout my home network. Rather than needing a separate antenna connection at each television, I can access live TV wherever I have a network connection. The flexibility alone makes this a great value. Integration with Plex was equally easy. I run Plex Media Server on my NAS, and adding the HDHomeRun was simple. Having a program guide and DVR functionality through Plex has been a great added bonus. Another feature I really appreciated was the accessibility of the tuner's signal diagnostics. We were able to put together a simple custom web service that monitored signal strength and quality across multiple channels while I experimented with antenna positioning. Being able to access that information programmatically made fine-tuning the antenna much easier and demonstrated just how versatile this little device can be. Overall, the HDHomeRun FLEX 4K has exceeded my expectations. Between the easy setup, excellent performance, Plex integration, and flexibility of four network-accessible tuners, I feel it's well worth the price. Highly recommended!
