“Converter box” can mean a few helpful devices on this page. Each solves a different connection or signal need for older TVs:

• Over-the-air digital TV converters: Turn broadcast digital signals into a format your TV can display and often add features like channel guides or USB recording.
• AV-to-HDMI upscalers: Send VCR, camcorder, or DVD composite/S-Video to an HDMI input on a newer TV.
• HDMI-to-AV adapters: Feed a streaming stick or Blu‑ray player into an older TV’s RCA inputs.
• RF modulators: Convert AV/HDMI sources to coax so very old sets can tune them on channel 3/4.

Choosing the right type depends on what you’re connecting and which inputs your TV has.

Over‑the‑air converter boxes can receive free local broadcasts when paired with a suitable antenna. Performance typically depends on your distance from towers, building materials, terrain, and antenna placement.

• Antenna matters: Try placing it high and near a window, or consider outdoor options when possible.
• Connections: Pick a box with outputs your TV supports (HDMI, RCA, or RF).
• Setup: Run an initial channel scan, then re-scan after moving the antenna or during seasonal changes.
• Extras: Some models add program guides, closed captions, and USB recording.

Results can vary by location and equipment, but many households receive a solid lineup of local channels without a subscription.

Focus on features that match your TV and viewing habits. Useful options include:

• Outputs: HDMI for newer sets; RCA or RF (channel 3/4) for older TVs.
• Recording: USB DVR/pause support and an on‑screen guide for scheduling.
• Upscaling: 720p/1080p video upscaling and aspect‑ratio control (4:3 or 16:9).
• Format compatibility: NTSC/PAL settings if you’re mixing devices or regions.
• Ease of use: A responsive remote, clear menus, and quick channel rescans.
• Media playback: Some units play common video files from USB.

If you’re connecting legacy gear (VCRs, game consoles), consider AV‑to‑HDMI upscalers. For very old sets, an RF modulator may be more practical.

You’ll receive the free, over‑the‑air channels available in your area. These typically include local network stations and their subchannels, but the exact lineup varies by location, signal strength, and antenna setup.

• Antenna required: The converter processes broadcast signals; it doesn’t add cable or satellite channels.
• Local factors: Distance from towers, buildings, and terrain can affect reception.
• Maximize reception: Place the antenna high, try different orientations, and perform periodic channel scans.
• Subchannels: Many stations carry additional networks on .2, .3, etc., which a converter box can display.

Lineups change over time, so rescanning occasionally can surface new or improved channels.

A few quick checks can help improve reception and setup:

1. Check connections: Antenna coax should go to the box’s RF input; then connect the box to your TV via HDMI, RCA, or RF.
2. Select the right input: Set your TV to the HDMI/AV input, or channel 3/4 if using RF.
3. Run a full scan: Use the box’s menu to scan for channels; rescans may be needed after moving the antenna.
4. Reposition the antenna: Higher placement and fewer obstructions can help.
5. Match formats: Ensure the box’s video/output mode (NTSC/PAL, 4:3/16:9) works with your TV.

Reception can vary by location and equipment, so results may differ.
