TV Antenna
A TV antenna picks up free over-the-air channels broadcast from local towers — no subscription needed. Whether it works well depends less on the antenna’s advertised “range” than on how far you are from the towers, which direction they are in, the frequencies they use and what is in the way. This guide explains how to check your reception, which type of antenna suits your location, and how to set it up.

ATSC 3.0 tunersStart with a reception check
- Look up your address on an official reception map — in the US, the FCC’s DTV Reception Maps; in the UK, the Freeview coverage checker; other countries have similar tools.
- Note each station’s distance, compass direction and whether it broadcasts on VHF or UHF.
- Check signal strength ratings: strong, moderate, weak or no signal.
- Choose an antenna that covers the frequencies and directions you need.
Distance and direction matter more than a marketing “range” figure, which is measured under ideal conditions.
Types of TV antenna
| Type | Where it goes | Best for |
|---|---|---|
| Indoor flat or loop | Window or wall | Strong signals, towers within roughly 20–30 miles |
| Indoor amplified | Window or wall, with a powered booster | Moderate signals, long cable runs |
| Attic | Loft or attic space | Moderate signals without outdoor mounting; roofing materials reduce signal |
| Outdoor directional (Yagi-style) | Roof or mast, pointed at towers | Weak or distant signals from one direction |
| Outdoor multi-directional | Roof or mast | Towers in several directions at moderate distance |
Compare indoor antennas, attic antennas and outdoor antennas, and check the frequency bands each supports.
VHF and UHF
Broadcast TV uses two bands: VHF (low channels 2–6 and high channels 7–13 in the US) and UHF (14–36). Many small flat antennas are designed mainly for UHF and high VHF and struggle with low-VHF stations. If your reception check shows important stations on VHF, choose an antenna specifically rated for VHF — they tend to have longer elements. The channel number you see on screen may differ from the actual broadcast frequency, so use the RF channel listed in the reception tool.
Directional vs omnidirectional
- Directional antennas pick up more signal from the direction they point and reject interference from others — best when your towers are clustered in one direction.
- Omnidirectional or multi-directional antennas receive from many directions — convenient when towers are spread around you, but usually with less gain.
- For towers in two different directions far away, some people combine two antennas or use a rotator.
Amplifiers: when they help
| Situation | Amplifier? |
|---|---|
| Long cable run or splitting to several TVs | A preamp or distribution amplifier often helps |
| Weak signal and good antenna placement | May help a little |
| Very strong nearby signals | Can overload the tuner and make reception worse |
| Poorly placed antenna | Won’t fix it — move the antenna first |
An amplifier boosts the signal and the noise; it can’t create signal that isn’t reaching the antenna. See TV signal amplifiers and look for adjustable gain or a bypass switch.
Cable, mounting and setup
- Use RG6 coaxial cable and keep runs as short as practical.
- Place the antenna as high as possible with a clear line towards the towers — an upstairs window beats a ground-floor one.
- Point directional antennas using the compass bearings from the reception map.
- Run a channel scan on the TV; rescan whenever you move the antenna or when stations change frequencies.
- Try small adjustments — a few feet or a few degrees can make a big difference.
- For outdoor installs, ground the mast and cable according to your local electrical code.

ATSC 3.0 (NextGen TV)
In the US, some stations now broadcast in ATSC 3.0, marketed as NextGen TV, alongside or instead of the older ATSC 1.0 standard. Any good antenna works for both — the difference is the tuner. To watch ATSC 3.0 channels you need a TV or external tuner that supports it; older TVs can only decode ATSC 1.0. Check which standard your local stations use.
See ATSC 3.0 tuners.
Who this guide is for
Anyone cutting cable or adding free local channels. We explain antenna types and specifications; we do not run hands-on reception tests. Reception depends on your location, so use an official reception map and check each product’s supported bands and return policy.
Frequently asked questions
How do I know which TV antenna I need?
Check an official reception map for tower distance, direction and band (VHF/UHF), then match the antenna to them.
Do indoor antennas work?
Yes, when you are fairly close to strong signals; distant or weak signals usually need attic or outdoor antennas.
Do I need an amplifier?
Only for long cable runs, splitting or some weak signals; it can make strong signals worse.
Why do I lose channels?
Obstructions, weather, antenna position or station frequency changes — rescan and try repositioning.
Do I need a special antenna for 4K or ATSC 3.0?
No, any antenna works; you need an ATSC 3.0 tuner for those broadcasts.
Does this site test antennas?
No. We explain types and specifications and do not run hands-on tests. Check each merchant’s page for current details.
