Setting up a Plex DVR with an attic antenna can give you access to over-the-air (OTA) channels, allowing you to watch and record live TV without a cable subscription. In this guide, I’ll walk you through the process step-by-step, from checking available channels in your area to completing the Plex DVR setup. I currently have an attic antenna and receive over 70 channels, so this setup works well!

Step 1: Check Available Channels in Your Area

Before you set up your antenna, check which channels are available in your area and where the broadcasting towers are located. Channel Master provides a great tool for this:

Enter your US zip code to get a map showing the locations and directions of nearby TV transmitters. This will help you point your antenna in the right direction for optimal reception

Step 2: Required Equipment

Here’s a list of items I use, and they’ve worked great:

Antennas Direct ClearStream 4V Indoor/Outdoor TV Antenna - Amazon

Antennas Direct ClearStream 4V indoor/outdoor TV antenna

This antenna is installed in my attic, and it picks up a wide range of channels.

Channel Master CM-7779HD PreAmp 1 TV Antenna Amplifier with 5G LTE Filter - Amazon

Channel Master CM-7779HD antenna preamplifier with 5G LTE filter

The preamplifier filters out noise and interference, and it’s powered via the coaxial cable, so you don’t need an outlet in the attic.

RG6 Coaxial Cable 50ft - Amazon

50ft RG6 coaxial cable for the antenna run

I opted for 50 feet, but you can choose a length that suits your setup.

RG6 Coaxial 3-pack (3ft each) - Amazon

Three-pack of short 3ft RG6 coaxial cables for internal connections

These shorter cables are useful for internal connections.

SiliconDust HDHomeRun Flex 4K ATSC 3.0 NextGen - Amazon

SiliconDust HDHomeRun Flex 4K ATSC 3.0 four-tuner network TV tuner

This device takes the antenna signal and converts it into a stream that Plex can use. The Flex 4K version has four tuners, allowing you to record up to four programs simultaneously.


Step 3: Installation Steps

Step 1: Install the Antenna

  • Mount the antenna in your attic or outside. Choose a location with minimal obstructions in the direction of the broadcast towers.

Step 2: Point the Antenna

  • Use the TV Antenna Map to determine the direction of the towers and point the antenna accordingly.

Step 3: Connect the Channel Master PreAmp

  • Mount the Channel Master near the antenna.
  • Connect the coaxial cable from the antenna to the Channel Master.

Step 4: Connect to the HDHomeRun and Power Inserter

  • Run a coaxial cable from the Channel Master to the power inserter, which should be located inside your home near the HDHomeRun device.
  • Connect another coaxial cable from the power inserter to the HDHomeRun.
  • Plug in and power up the HDHomeRun. Avoid placing the HDHomeRun in the attic, as high temperatures can damage the device.

Step 4: Set Up Plex DVR

  1. Open Plex Web App
    • Navigate to Settings > Live TV & DVR in the Plex Web App.
  2. Start the DVR Setup
    • Click the DVR Setup button to launch the setup wizard.
    • Plex will automatically scan your network for compatible devices. If the HDHomeRun isn’t detected automatically, you can manually specify its location.
  3. Channel Scanning and Lineup Matching
    • Once detected, the wizard will scan for available channels.
    • Plex will attempt to match the scanned channels with the correct program guide lineup.
    • Review the mapped channels and adjust them if needed. You can uncheck channels you don’t want or remap incorrect matches.
  4. Complete the Setup
    • Once you’ve configured the lineup, select Continue to download the electronic program guide (EPG) data.
    • If Plex finds additional tuners, you will have the option to configure them as well.

For detailed instructions on managing live TV and DVR settings, refer to Plex’s official guide: Live TV & DVR Setup and Management.


Final Tips

  • Tuner Placement: Keep the HDHomeRun in a cool, indoor location.
  • Program Guide Accuracy: Occasionally check for updates or rescan channels if you notice any discrepancies.

With this setup, you’ll be able to enjoy live TV and schedule recordings through Plex seamlessly. Happy viewing!
