Essential Info

This amplifier is ideal for pre-amplifying the signal coming in from the cable company or outdoor antenna. It's wide frequency range means that the amplifier is able to handle all frequencies on the TV band. The amplifier uses precision surface mounted components in a "push-pull" circuit design that results in low-distortion, high reliability, and a compact size. An external power supply isolates the AC line noise from the amplifier's circuitry. This contributes to the high performance and low distortion of the signal.


What's Included

  • 18dB Fixed Gain Amplifier
  • Power supply
  • More Info

    The item arrived and has been installed. The cable reception is clearer.
    THEODORE -- libertyville, IL   8/21/2009
    This is pretty much plug and play. I've got a 4 way splitter behind the amp running TVs thru old-old wiring and the signal quality is excellent. I'd rate it 5 stars but I'm not doing anything exotic with it.
    THOMAS -- kaneohe, HI   4/24/2008
    Does one thing very well: amplified my modulator signal after a long run from my camera. Very clean signal boost.
    PETER M -- minneapolis, MN   2/8/2007

    Excellent quality amp!
    BRUCE M -- bloomingrove, PA   9/3/2003
    Got it installed it, it works!
    JOSHUA -- anaheim, CA   8/28/2003
    When used with an antenna, the amplifier was too much. When used with cable before distribution, it worked fine.
