That Channel Master ought to work well for you, especially if you can get it well up into the air. My antenna (the bottom) is typically about 2' above the TT roof.
With these bowtie antennas, the active element (the bowtie) receives signal directly and reflected by the cross rods. The rods tend to enhance certain frequencies. I have seen on that antenna Forum that some users place either a foil sheet or a fence panel behind the rods and therefore, get even better sensitivity. If your broadcast stations are not all from one direction, that can work against you as stations behind the antenna will be somewhat blocked by the additions.
Good luck with your new antenna!
