ANTIER [2023 Release] 400+ Miles Range Indoor TV Antenna - HDTV Antennas are 8K 4K Full HD Compatible, with Best Powerful Amplifier & Signal Booster, 16ft Coaxial Cable for Smart & Older TVs

✔ If you want to improve the signal of the indoor digital TV antenna, moving it closer to a window or placing higher up on a wall might do the trick.✔ The digital TV signal is a ‘line of sight’ type of signal. Typically, the higher you have your indoor TV antenna, the better the reception. While signals pass through walls and other surfaces it encounters more obstructions which results in a weaker and disrupted signal. The clearest, most unobstructed view to the broadcast towers will allow the antenna to perform at the highest level.✔ The main disadvantage is that roofing materials may prevent the antenna from picking up channels clearly. Other factors like fluorescent lights and computers may also have a negative effect on your TV receiving a clear picture from the antenna.✔ 360design pulls in signal from all directions. If a signal cannot be received with the amplifier, remove the antenna amplifier and try again. You can try a flexible position for the optimal signal reception, especially for a TV located away from the window . ✔ The antenna can support 720P, 1080P, 4K and 8K, ASTC, and so on, but please do not place the antenna very close to the magnetic products, they aslo interfere with signal and magnetic objects will deteriorate image quality. You should place the antenna far away from Magnetic products and locate the antenna close to the window, facing outside.Technical Specifications Type: TV antenna Brand Name: ANTIER Frequency Range: VHF174-230/ UHF470-862Mhz Gain: 5dB/25dB with amplifier VSWR : 2.0 Polarization: vertical Impedance: 75 ohms Size: 60*148.5mm Cable Length: 16 ft Power supply: By setbox Connector Type: F male or customized
