[TowerTalk] Rotor damage from Shunt Feeding your tower?

[RLVZ--- via TowerTalk]

Hi Guys, 
 
Have any of you had damage to your rotor  box due to high RF from Shunt 
Feeding your tower or by suspending an Inv. L  from your tower?  
 
I get 10-20 degrees of meter movement on my Ham IV  control box when shunt 
feeding my tower or when using an Inv  L.  
 
Thanks & 73,
