Thanks for the photo of your antenna. That looks like a medium gain all-band antenna for channels on VHF-Low, VHF-High, and UHF.

Could you give me a suggestion of a UHF antenna to use?

The antennas suggested by Tower Guy are suitable.
DB2E

I'm thinking of going with tower guy's suggestion, but a little fuzzy on where to combine the signals. If it's up on the roof, will water be a problem?

The problem is with the preamp. You need the preamp for the weaker VHF signals from 342 degrees using your present antenna, but you must not use a preamp for your local strong signals from the UHF antenna. If you put the combiner outside between the antennas and the power inserter inside, then the combiner must be able to pass power to the VHF antenna preamp. But, that type of combiner is no longer available; only the ones that would pass power to a UHF antenna preamp, which you don't need.
That is why you need two coax lines coming down.
Code:
DB2E > coax > grounding > coax >
block \
UVSJ > splitter > TV
/
VHF > preamp > coax > grounding > coax > power >
ANT block inserter
The first thing you must do is to use just the DB2E to get the locals OK. Then, add the VHF antenna with the combiner.
