Product does not work
Bought this to amplify cable tv signal. After connecting, none of the cable boxes or the cable modem could receive a signal. Makes no difference whether the FM is in or out, or what gain level you initially start with.

    At first, I blamed overcast skies for the bad reception. I had to completely stop trying to watch broadcast TV programs. The reception became very bad on cloudly days and on clear days. After a month and a half, I decided to install a locally purchased antenna amplifier (with less gain) and was able to receive all broadcast channels on my television again. Unfortunately, the product return window for this amp closed on 1/31/2023.

    Reviewed in the United States on December 14, 2021

    I purchased this Model KF-235 Distribution Amplifier to replace a Radio Shack TV Antenna Amplifier that I thought was in the process of "dying", after being in service for at least 20 years. Location of Antenna and Amplifier is in the attic, and subjected to extreme heat, here in the Desert South West.
    I was very excited and impressed when the KF-235 arrived! By the look of this amplifier, it appears to be a very well made high quality product, and had the all-important "Gain Adjust" control that sold me on this item.
    After removing the old, and installing the new, I scanned for channels on my TV, and was surprised to see that the number of "Channels Found" had actually DECREASED to 33, compared to 54, from the R.S. Amp.. These results were with both units having their Gain Adjusts at minimum (fully CCW). Red Power Indicator on the KF-235 was "ON".
    Okay ... so I thought it's time to increase the Gain on the new KF-235 and good things were about to happen. Unfortunately, not true.
    My Toshiba TV has a "Signal Strength Indicator" that can be observed, for each channel, while in the set-up menu. I used this to document signal level changes on each channel as I systematically adjusted the Gain Control being set at: 8 O'clock (33 Channels Found), 10 O'clock (29 Channels Found), 12 O'clock (37 Channels Found), 2 O'clock (39 Channels Found), and 5 O'clock (37 Channels Found) positions. Apparently, the Gain Control was doing SOMETHING, however, the individual signal levels for each channel WERE NOT increasing, and no improvement occurred in channels having pixilated video. I spent MANY HOURS taking data from the Signal Strength Indicator, for each channel, trying to find the "sweet spot" for improved reception, but could not.
    Bottom line ... this KF-235 Distribution Amplifier appears to be a very well made high quality product! IT'S POSSIBLE THAT I RECEIVED A DEFECTIVE UNIT, however, I've found another (Name Brand) TV Antenna Amplifier that I'll be ordering / trying, and returning this one.
    Very much wish this one had worked for me! DISAPPOINTED !!!

    This is the 2nd one that lightning has ZAPPED! Our antenna is located in the attic. I know the amp is dead when after a severe thunderstorm our TV's only get 8 or 9 digital channels. Climb into the attic, unplug the dead one(I know it's dead because the red LED is dim), disconnect the coax, plug in the new one, reconnect the coax, climb down from the attic. Now we have over 60 digital channels again!

    If you’re using this for its intended use it’s a 5/5 so I’m giving it that, if you’re using it to make a personal VHF channel, it’s a 3/5. Still got it working pretty great with a direct connection with the antennae

    Superó mis espectativas, con su potencial ganancia de hasta 36dB, funciona de maravilla para mejorar considerablemente las señales débiles de estaciones de radio FM de otras localidades que se logran captar con la antena aérea.
    En el caso de los canales de tv, su interruptor de bloqueo para señales FM permite optimizar la recepción clara de canales antes pixeleados, solo recomiendo atenuar la graduación de los dB del amplificador para el caso de señales de tv fuertes de origen para evitar o atenuar la saturación de color que podría experimentarse en los canales si el amplificador se tiene trabajando al máximo de dB
