**Short answer:** **Pick an antenna by your distance from the broadcast towers and the bands your stations use, not by advertised "mile range".** Look up your address on the **FCC's DTV Reception Maps** (or RabbitEars.info). If your stations are **strong and within about 25 miles**, a **flat indoor antenna** near a window usually works. For **weaker signals, hills, or 25–60 miles**, mount a **directional antenna in the attic or, better, outdoors** and aim it at the towers. Check whether any station uses **VHF** (channels 2–13): many flat antennas receive it poorly. Add an **amplifier only** for long cable runs or splitters, not to fix a weak signal at the antenna.

## Key takeaways

- **Start with the FCC map:** it lists each station's real channel, band, signal strength and tower direction for your address.
- **Outdoor > attic > indoor.** Height and line of sight matter more than antenna size.
- **VHF stations need VHF elements**, which most small flat antennas lack.
- **Amplifiers** overcome cable and splitter losses; near strong towers they can overload the tuner.
- **ATSC 3.0 (NEXTGEN TV)** uses the same antennas; you need a TV or box with an ATSC 3.0 tuner.

Free over-the-air TV still delivers local news, network shows and live sports in better quality than many streams, without a subscription. The antenna is the part people get wrong, mostly by trusting the "mile range" on the box. Here's how to choose from your actual signal.

## Step 1: look up your signal

Enter your address on the **FCC's DTV Reception Maps**. For each station it shows:

- **Signal strength** (strong, moderate, weak or none, color-coded),
- **Real channel** (the RF channel actually used, which can differ from the channel number on screen),
- **Band**: **UHF** (RF channels 14–36 since the 2016–2020 repack) or **VHF** (channels 2–13),
- **Distance and direction** to the tower.

RabbitEars.info gives the same data in more detail, including signal predictions at different antenna heights.

## Step 2: choose the type

| Your situation | Antenna | Why |
|---|---|---|
| Strong signals, towers within ~25 miles, all UHF | **Flat indoor**, near a window facing the towers | Cheap, discreet, usually enough |
| Moderate signals, or one VHF station | **Indoor or attic antenna with VHF elements** (dipoles or loop) | Flat antennas pick up VHF poorly |
| Weak signals, hills, towers 25–60 miles away | **Directional outdoor** (Yagi or combo), roof or mast | Height and aim make the biggest difference |
| Towers in different directions | **Multi-directional outdoor**, or a rotator | Covers stations from several sides |
| Apartment, balcony | **Balcony or window-mounted directional** | Covered by the FCC OTARD rule on space you control |

**Attic vs outdoor:** roofs, insulation foil and metal reduce signal, so an attic mount usually loses some strength compared with the same antenna outdoors. It's still far better than indoors for weak signals.

## Step 3: amplifier or not?

An amplifier (preamp) boosts the signal to make up for **losses after the antenna**: long coax runs, splitters feeding several TVs, or a thin cable. It **can't create signal** the antenna doesn't catch, and close to powerful towers it can **overload** the tuner and make stations drop out. Rules of thumb:

- One TV, short cable, strong or moderate signals: **no amplifier**.
- Several TVs on a splitter, or 50 ft+ of cable: **a distribution amp or preamp**.
- Mixed strong and weak stations: try without first; add a preamp with adjustable gain if needed.

## Step 4: install and scan

1. Aim at the towers (the FCC map shows the compass direction).
2. Use RG6 coax and as few splitters and adapters as possible.
3. Run the TV's **channel scan** after every move of the antenna.
4. Rescan every few months; stations change frequencies occasionally.

## ATSC 3.0 (NEXTGEN TV)

NEXTGEN TV broadcasts on the same channels, so **any good antenna works**. To decode it you need an ATSC 3.0 tuner: see which current TVs have one in [ATSC 3.0 TVs](/atsc-3-tvs/). Some stations encrypt their ATSC 3.0 signals, which certain tuners and converter boxes can't play.

## Frequently asked questions

### What is the best TV antenna?

The one that suits your location: a flat indoor antenna for strong stations within about 25 miles, and a directional attic or outdoor antenna with VHF and UHF elements for weaker or more distant stations. Check your address on the FCC's DTV Reception Maps first.

### Do smart TVs need an antenna for local channels?

To get free over-the-air local channels, yes. Connect it to the TV's antenna (RF) input and run a channel scan. Streaming apps don't replace local broadcasts unless you subscribe to a live-TV service.

### Do amplified antennas work better?

Only in some cases. An amplifier makes up for signal lost in long cables and splitters; it can't add signal the antenna doesn't receive, and near strong towers it can overload the tuner and make reception worse.

### Are antenna 'mile range' claims accurate?

Treat them as marketing. Real range depends on terrain, height, buildings, tower power and band. The FCC map's signal-strength rating for your address is a far better guide.

### Do I need a new antenna for ATSC 3.0?

No. NEXTGEN TV (ATSC 3.0) uses the same UHF and VHF channels. You need a TV or converter box with an ATSC 3.0 tuner.

### Can renters or HOA residents install an outdoor antenna?

In many cases, yes. The FCC's Over-the-Air Reception Devices (OTARD) rule limits restrictions on antennas installed on property you control, such as a balcony or patio. Common areas and roofs you don't control are excluded.
