Do ADHD father's angry outbursts affect children?

I'm interested in hearing from anyone but especially people with teenagers or older children on how/if an ADHD father's low frustration tolerance and angry outbursts have affected their children. I have two young ADHD children and wonder if seeing their father's reactions will affect them in the long run. I think the children need patience and calm voices which my husband with untreated ADHD has trouble providing sometimes. Husband's sudden outbursts can be about anything from other drivers, long lines, people/cars moving slowly, spilled water/food, etc.
