1 - Improving the performance of your indoor digital TV antenna can often be achieved by simply relocating it. Moving the antenna closer to a window or mounting it higher up on the wall can greatly enhance its signal reception. 2 - The digital TV signal is a line of sight type, and a higher placement of the indoor TV antenna typically results in better reception. Obstructions like walls can cause weaker and disrupted signals, so an unobstructed view to the broadcast towers is ideal for optimal performance. 3 - Roofing materials and other obstacles like fluorescent lights and computers can negatively impact your TV's signal from the antenna. 4 - The 360° design of the antenna allows it to receive signals from all directions. If the signal is weak even with the amplifier, try removing the amplifier and adjusting the antenna's position for optimal reception, especially for a TV located away from the window. 5 - The antenna for smart TV is compatible with 720P, 1080P, 4K, 8K, ASTC and more, but to avoid interference with the signal, keep it away from magnetic objects. Magnetic objects can also degrade image quality, so place the antenna close to a window, facing outside, and far from magnetic products.
