J-poles are often dual band. If you are looking for a simple dual band antenna it works pretty well for line of sight radio.
For the better omni directional gain, a vertical collinear phased array antenna is the solution. They can even be tuned with down tilt for coverage from hilltops. Many are made from UHF coax and or copper tubing sections. There are some excellent commercial antennas made that way.
VHF and UHF are not normally for over the horizon radio.
If you want real directional gain, the Yagi, corner reflector, patch antenna and Parabolic dish are the solution.

certainly not UHF

SO DOES a wire sticking out the back of the RADIO.
You nutjobs just won’t let it go, will you?
You’re either green and new to radio, or so old you forgot ALL you learned.
EITHER WAY, J-poles still SUCK.
People like spread myth and disinfo without the slightest understanding what the hell you’re doing to NEWBIES.
