Gateway devices like the HDHomeRun and Tablo (compensated affiliate links) take over the air television signals from an antenna, put them on your local network, and let you stream live television like any other app to just about any device. They even have DVR features for recording, too.
Beyond the cool factor these devices can also save you a lot of money in cable and streaming fees. My latest explainer video takes a hands-on look at these devices.
The HDHomeRun Flex 4K, for instance, allows users to watch or record up to four different channels simultaneously. This functionality—combined with the flexibility to use the device with various apps and platforms—offers a significant alternative to traditional cable services. Costs associated with these devices are often minimal compared to the steep and frequently rising fees for local TV broadcasts through cable and streaming providers. In my area, these fees can amount to nearly $400 annually, while a gateway device offers a much faster return on investment.
Setting up OTA television does come with a few challenges, particularly with antenna installation. Tools like the RabbitEars website can help identify the best placement and type of antenna for a given location. For those less inclined to set up an antenna themselves, services like Antenna Man offer personalized recommendations. Depending on geography, solutions range from small indoor antennas to larger outdoor ones, as seen with setups in rural or distant areas.
Despite these benefits, the freedom that gateway devices provide faces a looming threat. Broadcasters are pushing for DRM encryption in conjunction with the rollout of the ATSC 3.0 “NextGen TV” standard by 2027. If implemented, this could limit the current flexibility of accessing and recording OTA content, nudging consumers back toward paid subscriptions. Advocacy efforts have focused on challenging this encryption, with significant public input on the FCC transition docket urging for continued device usability.
The transition to ATSC 3.0 is not without its advantages. The new standard promises improved video quality and modern encoding capabilities compared to the decades-old ATSC 1.0. However, compatibility with ATSC 3.0 is a critical factor for prospective device buyers. For example, while the HDHomeRun Flex 4K supports both standards, many devices, such as the current generation of the Tablo DVR, are limited to ATSC 1.0 and may become obsolete post-transition in 2027.
Manufacturers are working on solutions to maintain the functionality of gateway devices under the new standard, but ultimately the broadcasters will have to allow it.
