Gray Stars 4K High-Definition Digital TV Antenna, 360° Omnidirectional Reception, Magnetic Mounting, with SignalAmplifier, Suitable for Indoor and Outdoor Use, Ideal for Home/Camping

• Compatibility and Setup: 

Works with any HDTV (built-in ATSC tuner) – simply connect to the “ANT/IN” port, turn on the power, and scan for channels.

For legacy CRT TVs without a digital tuner – please use a digital converter box.

Compatible with Freeview, Mediasonic, ViewTV, and most digital receivers.

• Important Note (Read Before Buying):

Check your TV first—most flat-screen TVs from 2010 onwards have a built-in HD TV tuner. If you see "ATSC" or "Digital Tuner" in the menu, don't worry. If not, you'll need a digital converter box.

The signal source matters—not all digital signals are HD. Picture quality depends on the transmission signal of your local broadcaster (720p, 1080i, or 1080p/4K).

Avoid interference—keep your antenna away from high-powered appliances (air conditioners, elevators, hair dryers, microwaves). Metal roofs or thick concrete walls can reduce signal range.

Rescan regularly—broadcasters add or remove channels from time to time. Rescan your TV every 1-2 months to receive all available channels.
