An extremely low nose figure in a preamp, such as the Kitztech, has very little effect on TV reception. This is because the antenna is aimed at the horizon. Only when an antenna is aimed up at a satellite or celestial body will a noise figure less than 3 dB offer much improvement.

The exception is that a lower nose preamp can be located further from the antenna, after some feed line loss, or after a band pass filter, and still offer an advantage.
