[TowerTalk] shut fed tower and rotator

I recently built 2 verticals for 80 and 160 by shuntfeeding my tower. They both seem to load nicely and are broadbanded, partly because of an insufficient radial system.
When I transmit on either 160 or 80 the meter on my rotator controller deflects.... this makes sense since I'm running rf right through the rotator. Till now I've run only 100 watts thru the antennas but I'd like to see if the antennas will handle a KW ok. I'm wondering if there's any chance of damage to the rotator (Ham IV) if I do this. I'd guess not but it makes me a little nervous.
Currently 10 watts deflects the meter about 10%. 100 watts deflects it about 25%.
Anyone have a thought on this?
Thanks,
