If all channels are behaving the same, then you have a problem that's common to all of the.
I would start with one TV, the balun, a length of coax and the antenna, only.
I would then, add one component at a time, until it starts acting up.
Hopefully, this will help pinpoint the problem a little closer.
You don't say if this is a new problem to an existing system, or just some kinks that need to be worked out of a new install.
Yes, a taller mast can help.
I have also heard where even lowering it by inches, may help find that sweet spot.
