The CM4228HD does better at receiving at the low end of the UHF.
Channels 14 thru 30 where you require it the most , that is why I recommend the CM4228HD for your reception.

And the CPA-19 preamp is a low noise mid gain preamp that will tolerate high signal strengths with out over load , and works with other antennas , that is why I recommended it.
