If you are building a dummy load, there are no diodes in them, they are pure resistance only.
Carbon resistive material with NO conductive coating.

Diodes are for tapping RF and converting it to a DC voltage for metering, also used in conjunction with a capacitor to keep the impedance within tolerance.
