Engineered and designed in the USA by Antop, the antenna specialists, the Antop SMARTPASS AMPLIFIER features a SMART SWITCH to balance the amplification between short and long range signals received by the antenna. The Smart Switch is recommended to be switched ON to boost weaker signal level reception, and switched OFF to avoid amplification overload for stronger signal reception. The SMARTPASS AMPLIFIER is not recommended for use with an amplified antenna.


The Antop Smartpass Amplifier, AT-601B,is designed to work with any non-amplified/pass antenna to boost the over-the-air TV signal received by the antenna. The attached 3ft and 0.3ft extension coaxial cables at either end offer connection flexibility and enable you to move the antenna within a wider placement range for better reception. The AT-601B supports over-the-air TV signals including HDTV, 1080P TV and 4K ULTRA HD.
