Did you try the antenna suggested by teleview?

Reliable reception depends more on signal quality than raw signal strength. Mixing the output of two antennas via a reversed splitter might produce more signal power, but the combination of signals is lower in quality due to an effect analogous to an echo.

While it's true digital format broadcasting is done at slightly lower power than analog, You have over 20,000 time more power in the air than needed for theoretical minimum reception levels. (KCTS, real CH-9 predicted NM >43 dB).

For connection to a single tuner, no amplifier should be needed.

Focus on signal quality, not strength. To improve signal quality, locate the antenna where it has no obstructions when aimed at Queen Anne and Capitol Hill (Downtown Seattle)... Use an antenna that has directional characteristics, so that reflected signals arriving from indirect paths will be attenuated as much as possible... Keep the antenna away from sources of interference.

As an aside, the Mohu leaf is a UHF only design, so not likely to offer good reception of real CH-9, a VHF channel. It's not clear what the other antenna is...
