How to change an ability to have ranged damage falloff or not

[vaccus]

I am trying to mod a new type of bow to have no damage range fall off like a long bow, but I cannot seem to find the property to edit that will make this change. I can make a bow that fire but it still does less damage at long range. Where is the property located that needs to be edited to change this?
Thanks
P.S. I am looking at the aowunitproperties.rpk under than ranged abilities category.

Find the Longbow or the Swarm Darter ability and copy what you see there.
(do you plan on answering people who answer you or? 3rd post I answer and no feedback)

That didn't work but I found the entire damage class had to be changed and not just a simple true false tag like I would have thought.
But thanks for the response.
