Are over the air VHS digital TV signals more or less reliable than UHF digital over the air TV signals?
I receive a local digital UHF TV channel over the air, but I cannot receive a local high-VHS over the air digital TV channel that broadcasts at much higher strength.
The antenna is for both UHF and VHS signals.
What could be the problem?

First, it’s VHF, very high frequency.
I’m surprised that you say the VHF station is much higher strength. That is generally not the case in most areas. Whereas UHF channels often broadcast at 1000 KW, most VHF stations use 100 KW or less with 20KW being pretty common.
Being lower frequency than UHF, VHF signals tend to propagate much further than UHF for the same power. They are also able to bend (diffract) around obstacles like buildings, hills, etc, while UHF tends to be pure line of sight. Because of these propagation characteristics, the FCC places lower power limits on VHF stations to avoid them interfering with adjacent TV broadcasting areas.
The only thing I can suggest is an antenna with better VHF performance, mounted high on your roof.
You can check the station’s power and location (maybe you need a rotor), at one of the following sites.

The TVfool site is especially good.
