I use those Caddock Thick Film Power resistors to make my own dummy
loads. They make flat dummy loads up to at least 200MHz with normal
lead dress, and with care they can be flat up to 500MHz.
I have found is that the 50 ohm resistors are non-reactive, but other
values may be capacitive.
They MUST be used on a heatsink adequate for their power rating or else
their power rating is quite low. They will zap in an instant if their
power rating (device and the heatsink) are exceeded, so put them on a
heatsink that is sufficient for the power rating.

The good non-inductive resistors are made by Caddock Electronics. Available
from some of the catalog dealers.
