The net effect of installing the amplifier on the end of 100' of RG-6 would be equivalent to adding about 6 dB to the noise figure of the amplifier.
While measurable, the difference in noise figure will rarely make enough difference in reception reliability (comparing the KT-200 vs a preamp with a NF of 2 to 3 dB). Signal level variation due to fading and transient impulse noise can greatly exceed the 1.5 dB or less gain in net system NM.
For the user who is willing to build an enclosure just below the antenna, who is going after very weak signals, the KT-200 may be part of the optimum system design.
For most consumers, the products from Antennacraft, Antennas Direct, Channel Master and Winegard will be easier to install and will provide the needed gain to overcome cable and splitter losses.
