The DB8e will offer a better chance of picking up the lower UHF channels due to its higher gain, especially at the low end of the UHF band compared to the 91XG.

I'd pair it with the PA18 preamplifier and get it mounted above the trees, if possible (or trim the tree tops).

We recommend that all outdoor antennas be grounded in accordance with local or national electrical codes. There are extensive threads elsewhere in this forum that cover aspects of grounding. Keep in mind that antenna grounding is not meant to contain the effects of lightning, they are to 1) reduce the chance of lightning by draining off static charges making the antenna mast the same potential as ground and 2) protect against accidentally energizing the system should it come in contact with live power lines.
