think you would be much better off getting a folded dipole antenna like
a DB224 for VHF or a DB411 for UHF. You can set the dipoles to favor
the town by putting 3 facing the town with one left facing the opposite
direction so the back door isn't too badly affected.

Then I'd take a DB-224 antenna and point the elements toward your desired
areas. If you split and mount another antenna elsewhere, you are going to
create a highly unpredictable pattern with two different radiation centers,
creating multipath possibilities. At least that's my take.

Your omni + yagi configuration will work. It has been used in the land mobile
field for many years, but not very often. You get a keyhole shaped pattern.
Phasing shouldn't be a big issue but feel free to play with cable lengths. Use

I agree, if you don't hear anything else in the mix, and it pretty much
