"Initial tuning of this unit must be done at power levels of 10 watts or less. Severe damage can result to untuned units by the application of power in excess of this limit." I can see a TX being damaged by excessive reflected power from an untuned isolator's input, but damage to the isolator? Reason I bring this up is because when I tune an isolator with a TX, I put another (already tuned) isolator between the TX & the isolator being tuned to make sure the latter sees 50 ohms on all ports. So I don't have to worry about what the TX sees because it's already isolated, but I also run ~30 watts or so to get a good indication on the Bird using a 50 watt slug. Bob NO6B Yahoo!
