ANTOP AT-402B Amplified Outdoor/Indoor TV Antenna

The AT-402B digital TV antenna, engineered and designed in the USA by ANTOP, the antenna specialists, features NEW GENERATION DIGITAL TECHNOLOGY and is designed to match the similar gain of traditional bulky, unsightly mechanical antennas. With an amplified signal reach ranging from 0 to 60 and 70 miles from the point of origination, it assures more channel reception and fewer blind spots.

Redesigned to provide a multi-directional, High Gain reception on par with traditional antennas, the AT-402B utilizes ANTOP's exclusive Smartpass Amplifier System and 4G LTE Filter to amplify your range. The Smartpass Amplifier System allows for an easier connection and more possibilities in different receiving ranges, with a yellow light indicating short-range reception when switched off, and a green light indicating long-range reception when switched on. The built-in 4G LTE Filter blocks unwanted 3G/4G interference, ensuring noise-free digital TV reception - ANTOP was the first antenna manufacturer to include this feature.

The AT-402B's sleek, durable design features an anti-UV and waterproof exterior, making it suitable for both indoor and outdoor use, including wall, roof, balcony, or tabletop installation. Its quick and easy set-up process involves connecting the coaxial cable, power inserter, and power source, then adjusting the antenna positioning and scanning the channels.

Technically, the AT-402B has a frequency range of 87.5-230MHz and 470-700MHz, with a VHF/UHF gain of 12.5dB or 29dB, a maximum output level of 100dBuV, and a 75Ω impedance. The noise figure is ≤2.5dB, and the reception pattern is multi-directional with horizontal/vertical polarization.

Antenna effectiveness is influenced by factors such as distance from the signal origination point, station signal strength, antenna positioning, reflections from nearby structures, and any power consumption sources. To ensure optimal performance, position the antenna to face the broadcast tower, in a location as high as possible, with a clear path between the antenna and the broadcasting towers.

The AT-402B is compatible with TV converter boxes and digital televisions/4K Ultra High Definition (4K UHD) TVs. Each ANTOP product comes with 24-hour access to online customer support and installation assistance.
