You want to prevent KB from your own Power?
To the best of my knowledge there are no Patron Powers (or Hero Epics for that matter) that prevent KB. PFF might make a KB Power hit less but does not actually prevent KB that I know of.
Why are you asking? Putting the question in context might help.

Mu Cages is -kb.

Mu Mastery's Electrifying fences has a 10 second -kb attached to it. This may sound all nice and pleasant, an AoE immobilize with -kb, but it's radius is 10'. This is so small, that unless you have the mob grouped up already before you hit them with it, you'll be lucky to get more than 2 in a single instance of the power. I got it an respeced out of it shortly after I realized how little it did for mitigating the chaos.
Yeah, Web Grenade has no -KB, but has a very nice large AoE, and is -Fly too.
Just saying...
I am looking for a way to help my Tornado (/Storm) do more damage. Not to mention KB lowers the damage from my Arsonist also (Thugs/)
There are plenty of times I like the knockback, I am just looking for a power which will let me not have it at times also.
Use your hurricane to corner herd. Once you have them relatively stuffed into a right angle, you can let loose with the tornado and it will just assist your hurricane/gale in keeping them all cornered and in the arsonist burn patches. Alternately you can pull around corners with snow storm. While you can't slot it for range with standard IO's, there are a few range/* set IO's which will increase it's range. Which makes it a safe herding tool AND a pvp nightmare.
Although it doesn't help specifically with tornado; slotting the Ragnarok knockdown proc and one of the slow sets can help to keep peeps on the storm patch so that it's easier to herd them into corners.

What they said. Hurricane, properly slotted, can be your friend.

Ok, I was hoping one of the patron powers would do the job, but it doesn't sound like any of them would do it. I use Hurricane, buts its often cumbersome or not the right area for it.
Don't listen to them, mu electric fences does the job if you herdicane foes into one nice patch (just spam electric fences while you herd). Tornado is pretty crummy though in general, and it has a mind of its own. It will often chase after spawns you don't want it to, and the KB it generates will often blow guys out of corners even if you herd them into a corner with hurricane.
It's a panic button, imo.

still fun tho 
also not just panic imo.. against AV/hero/GMs tornato rocks, will sit on the boss an rack up DoT dam... Never misses, fire an forget, an watch the GM take 10.10.10.10 in background while you throw your main attacks at em.
i have electric fences onmy thugs/traps now.
soloing missions set for 3 people i team tp in and hit defensive/follow so the pets dont immediately attack back. i do this a few times until the mobs gather all around - then hit fences and poison trap. aid other any pet that did get hit (my pets are soft capped) and watch them melt. oftentimes if the map is big enough i pull two groups at a time. i can do this on 8 man, but the RNG chance for attacks to get through the soft cap and pop one or two of the tier 1's before i can get everything together skyrockets with mob densities that big - so on an 8 man team i just root what i can, toss caltrops so they run out of burn patches slower and put web grenade on auto fire.
it's actually as fast as my bots/traps. bots incendiary missiles patches do more dmg than the arsonist fire bomb, but recharge very slow in comparison. plus the enforcer cones do insane dmg on top of that even being lethal dmg.
i had web envelope for nearly three years and the change in radius is quite noticeable. but so is having kb protection for 15s now.
Title says it all. I am looking for a way to prevent the knockback from my tornado.
