Digital Antenna TV Indoor Signal Amplifier 4K UHD - Black

HDTV with all digital terrestrial signal compatible: (dvb-t/t2, isdb-t, dumb-t/h, atsc) and dab/Fm radio.The antenna doesn't automatically pick up channels as soon as you plug it in. you need to scan for channels. also, don't place the thin-film antenna near the tv; it needs to be in a window or on a balcony. please, please, please remember this!

Receive the device when all three conditions are met:

1. digital TV (if you don't have one, you can purchase a digital terrestrial set-top box to pair with it). (make sure it's a relatively recent digital TV, older models might not be compatible.)

2. antenna placement: ideally, place the antenna on the second floor or higher, in a location with a good view (e.g., a window, balcony, or rooftop). the higher, the better! in rural areas, the rooftop is recommended. [avoid placing it on the ground floor or near the TV.] the installation location is crucial, so take the time to adjust it for optimal reception. remember to rescan for channels each time you move the antenna.

3. local ground wave transmission station available.

The number of units received is determined by the number of transmitters opened (the upper limit is determined)

Urban and rural areas should be no more than 30 kilometers away from the county seat.
