Batboard

Hello
I built a dummy load from batsite
works great for vhf but very low voltage uhf is there a diode I should use besids 1n34a
thanks

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.
