See link for an rf probe I made for a friend who is a HAM.

**broken link removed**

Since Ge point contact diodes were not available, and I had a few dual diodes (connected in series) in SOT package, I used that, and in order to offset the forward drop supplied about 1.2 V from a button cell and trimpot.

Is this method going to be as good as using a Ge diode?

Are there any drawbacks to using Si diodes in an rf probe?

Since this is my first tentative venture into the realm of rf design any comments would be greatly appreciated.

(my friend, VU2SWX, is greatly delighted with the probe, I should mention)
