Any resistor except a big wire wound is "non-inductive" on a low frequency 
like 160.

What you want is a composition type resistor, either metal or carbon, to 
handle surges without changing value.

The last thing you want is a film resistor, which is what you probably have 
right now. Carbon films or metal films increase in value after short 
duration high energy surges, because the surge blows part of the film layer 
away.
