Product Benefits/Bullet Points

  • Works with any non-amplified/passive TV antenna. High gain is designed to amplify VHF and UHF SIGNALS with a LOW NOISE level, less than 2dB. Dual-color indicator, Green for long reception and Yellow for short reception. 3ft and 0.3ft EXTENSION COAXIAL CABLES are attached at either end for easy connection. AT-601B(Black) must be powered to function. Unit can be powered via the included USB cable by connecting to any USB power adapter supporting 5V output on USB-port.
  • 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 SMARTPASS AMPLIFIER, an exclusive technology offered only by ANTOP, uses an all-in-one design to allow an easier connection between a non-amplified/passive antenna and your TV delivering the correct balance between short and long range reception. ANTOP was the first antenna manufacturer to include a BUILT-IN 4G FILTER in all their amplified products to BLOCK 3G and 4G wireless signals to ensure NOISE-FREE digital TV reception.
  • Tips: When using an AT-601B SMARTPASS AMPLIFIER with any non-amplified antenna, note that antenna effectiveness is also influenced by its distance from the signal origination point, station signal strength level, building construction, antenna positioning, reflections from nearby structures and any power consumption sources. The amount of free over-the-air channels you can receive will vary by area and atenna selection, check signal availability at Signal maps
