One Antenna for Your Whole House? Here's How Network Tuners Work

Learn how network tuners let one antenna serve your entire home. No coax cables to every TV - watch on all devices wirelessly.

One Antenna for Your Whole House? Here's How Network Tuners Work

Last Updated: October 2025

Running coaxial cable to every TV in your house is expensive, difficult, and often impossible. What if you could use one outdoor antenna and watch on every TV, phone, and tablet in your home?

That's exactly what network tuners do. This guide explains how they work and why they're game-changers for cord-cutters.

The Old Way: Coax to Every TV

Traditional antenna setup:

Roof Antenna
    ↓ (75ft coax through attic)
Living Room TV

Roof Antenna
    ↓ (100ft coax through walls)
Master Bedroom TV

Roof Antenna
    ↓ (125ft coax through basement)
Basement TV

Problems with this approach:

  • Need to run coax cable through walls, attic, or crawl spaces
  • Expensive installation ($50-100 per room professionally)
  • Difficult in apartments/rentals (can't drill holes)
  • Signal loss over long cable runs
  • Can't watch on phones/tablets
  • Each TV needs its own antenna connection
  • No way to share recordings between TVs

Cost for 3 TVs:

  • 3x outdoor antennas: $120-$400
  • 300ft coax cable: $40-80
  • Installation labor: $150-300 (if not DIY)
  • Total: $310-$780

Plus you're still limited to the TVs you wired. No tablets, phones, or future rooms.

The New Way: One Antenna + Network Tuner

Network tuner setup:

Roof Antenna
    ↓ (50ft coax to attic/utility room)
Network Tuner (HDHomeRun)
    ↓ (ethernet cable to router)
WiFi Router
    ↓ (wireless or ethernet)
ALL TVs, Phones, Tablets, Computers

Advantages:

  • Only one coax cable run (from antenna to tuner location)
  • Network tuner near router (easy installation location)
  • Every device in your home can watch
  • Add TVs anytime without new cable runs
  • Watch on phones and tablets
  • Recordings available on all devices
  • Multiple people watch different channels simultaneously

Cost for whole house:

  • 1x outdoor antenna: $40-$140
  • 1x 50-100ft coax cable: $17-27
  • 1x HDHomeRun Flex 4K: $199.99
  • 1x Ethernet cable: $6.99
  • Streaming devices per TV: $50-$150 each
  • Total: $315-$524 for infinite devices

How Network Tuners Work

A network tuner is a device that converts antenna signals into streaming video that travels over your home network.

The Signal Flow

Step 1: Antenna Receives Broadcasts

  • Your outdoor antenna picks up signals from broadcast towers
  • Receives ABC, CBS, FOX, NBC, PBS, and other local channels
  • Full HD quality (1080i or 1080p)
  • Some channels broadcast in 4K with ATSC 3.0

Step 2: Antenna Sends Signal to Network Tuner

  • Coaxial cable carries signal from antenna to network tuner
  • Network tuner is typically located near your router
  • Only need one coax cable run (much easier than running to every TV)

Step 3: Network Tuner Converts Signal

  • Network tuner has 2-4 "tuners" inside
  • Each tuner can decode one channel at a time
  • Tuners convert broadcast signal to digital video stream
  • 4-tuner device = 4 people can watch different channels simultaneously

Step 4: Video Streams Over Your Network

  • Network tuner connects to router via ethernet or WiFi
  • Video streams travel over your home network (just like Netflix)
  • No special networking equipment needed
  • Works with existing WiFi and ethernet

Step 5: Devices Play the Stream

  • Streaming devices (Apple TV, Roku, Fire TV) use an app
  • App connects to network tuner automatically
  • You see a channel guide just like cable
  • Change channels, pause live TV, record shows

Real-World Example

Your house:

  • Antenna on roof
  • Network tuner in basement utility room (near router)
  • Living room: Apple TV on main TV
  • Master bedroom: Roku on TV
  • Kids' room: Fire TV Stick on TV
  • Kitchen: iPad on counter
  • Dad's phone: iPhone
  • Mom's tablet: iPad in bedroom

What everyone can do:

  • Living room: Watching NFL game on FOX
  • Master bedroom: Watching local news on NBC
  • Kids' room: Watching PBS Kids on PBS
  • Kitchen iPad: Watching cooking show on CBS
  • Dad: Watching recording of last night's game (anywhere in house)
  • Mom: Watching recorded show (anywhere in house)

All from one antenna and one network tuner.

How Many Tuners Do You Need?

Network tuners come with different numbers of tuners (2 or 4 typically). Each tuner can handle one channel stream at a time.

2-Tuner Device

What you can do simultaneously:

  • Watch 2 different channels on 2 TVs
  • Watch 1 channel + record 1 other channel
  • Record 2 channels while not watching

Good for:

  • 1-2 person households
  • Light TV watchers
  • People who don't watch much live TV

Example devices:

4-Tuner Device (Recommended)

What you can do simultaneously:

  • Watch 4 different channels on 4 different devices
  • Watch 2 channels + record 2 other channels
  • Record 4 channels while watching recordings

Good for:

  • Families with 3+ people
  • Multiple TVs in use at same time
  • Recording multiple shows during prime time
  • Sports fans (record multiple games)

Example devices:

What Happens If You Run Out of Tuners?

If all tuners are in use and someone tries to watch another channel:

  1. The app shows a message "All tuners are busy"
  2. You can see what's using each tuner
  3. You can stop one stream to free up a tuner
  4. Or wait until someone else finishes watching

In practice: With a 4-tuner device, you rarely hit the limit unless you're recording 4 shows during prime time.

What happens:

  • Antenna receives broadcasts → Network tuner converts → Streams over local network → Devices watch
  • All of this happens locally in your home
  • No internet connection used

Internet only needed for:

  • Program guide data (what shows are on)
  • Remote viewing (watching outside your home)
  • Streaming services (Netflix, Hulu, etc. on same device)
  • DVR features with some systems (like Tablo)

WiFi vs Ethernet

Ethernet (Recommended):

  • More reliable
  • No buffering
  • Lower latency
  • Better for DVR playback
  • Best for living room TV

WiFi (Works Fine):

  • More convenient
  • No cables to run
  • Good enough for live TV
  • Can buffer occasionally during peak usage
