Tip!: Setting up and using a DVR is a premium feature and requires an active Plex Pass subscription.
Cable and satellite TV subscriptions can be expensive and many people often forget that broadcast television is still free "over the air" (OTA). Anyone who wants a cheap and easy way to get programming from major and local networks can make use of digital TV. To make use of Plex DVR with OTA broadcasts, you'll need both a DVR device and an antenna.
If you do have cable service, though, you can still make use of a DVR that supports cable to let you view unencrypted content!
Plex Media Server Platform Support
The beta DVR functionality is currently available when running Plex Media Server v1.4.1 or newer.
Be aware that if you run your Plex Media Server on a low-powered NAS device that doesn't support transcoding, many apps will be unable to play recorded content. Over the air broadcasts are often in MPEG2 or other older formats, which few devices or apps can play directly (and would thus require transcoding in those cases).

Supported DVR Devices
Plex currently supports all HDHomeRun (HDHR) devices by Silicon Dust. (Older HDHR models require Plex Media Server 1.5.0 or newer.)
Tip!: If your HDHomeRun tuner doesn't show up, you may need to update its firmware. Ensure you're running the latest HDHomeRun Software.
You will need to connect your DVR to an antenna to be able to pick up the free digital Over the Air broadcasts.
Plex will work with any digital antenna, regardless of manufacturer. The best antenna for you can vary greatly based on a number of factors, including: your particular location, channels availability, and distance/direction from the broadcast sources. An "amplified" antenna may provide improved reception and allow you to reach more distant stations, particularly when using an indoor antenna.
Both the Mohu and HD Frequency websites have information about the different types of antennas that are available. There are also many other resources for great information and tips on choosing the most appropriate antenna for you, including the following.
