At the same time it removes the noise and won’t overload on strong signals.

You do realize the specs on that antenna are fudged? The unamplified gain should be measured with respect to a tuned dipole, not a 1-meter dipole.

Also, adding the amplifier gain to the antenna gain and calling it the amplified antenna gain is bogus. The amplifier gain is useful to compensate downlead loss. The apparent 15 dB gain of their amp (reading their graph) is more than enough, but the important amplifier spec is noise figure, which they don't give. If their amplifier noise figure is worse than your TV tuner noise figure, it can actually be a detriment.

Another important amplifier spec is overload level. At least they have an option to shut it off if it suffers overload from local signals.

"Removing the noise" is an odd sounding claim - there is no way to "remove noise" from a signal - but this seems to refer to the amplifier shielding, which will help keep unwanted strong local signals that the antenna is not directly aimed at from getting into the system.
