I strongly disagree.  What causes an excessively strong downlink signal is 
too much ERP (dish gain x tx power reaching the antenna)!  If you have a 
big dish you must reduce uplink power until you bring the ERP to an 
acceptable level.

  If you can't reduce it on the rig, don't operate until you have added an 
attenuator somewhere in the system.
