There are plenty of Allen Bradley 1w real carbon composition resistors on ebay at prices ranging from $0.25 ea to absurdium. Buy some that you can series/parellel to get the value you want. If it doesn't say A-B on the packaging, squash one in your vice. I've found wire-wounds inside some (likely Chinese) look-a-like claimed carbon comps, after tests made no sense. These are tough non-inductive resistors, but values may have drifted a bit with age.

They were supposed to be non-inductive carbon, but need to find something better like carbon film.

What kind of resistors are you using?

They shouldn't do that if you use the right type.

After recent night time thunder storm activity, two Beverage antennas lost some directivity. Termination resistors looked normal, but an ohmmeter checked reviled they had each gone
hundreds of ohms higher.  Replaced resistors and back to normal.
