Topband: Beverage antenna terminations

I lost several resistors on my WF until I started to use NTE 3 W Metal on
the vertical Waller Flag and on the Horizontal WF I am using an array of 9
parallel/series.

Since that I never replaced it a single time in the last 4 years. The
resistor has very low inductance but it is hard to find it, average price is
near U$1.

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