One thing to note with these RF probes it that I don't think it's a good idea (in terms of health and safety) to put them in an uncoated metal tube or box if they are being used with a handheld DMM.

If the operator is touching the metal case of the probe in one hand and is touching earth with another part of their body then they risk getting a nasty shock (or an RF burn?) if the probe croc lead can fall off and touch a live node on the equipment.

In all my years, I've never bothered with a screened RF detector probe and it doesn't seem to matter that much. My RF probe is based on the same cheap and throw away design I used as a student. It's just a long and thin strip of FR4 PCB cut in the shape of a pen. The handle section is just bare FR4 and only the very tip of the probe has any copper or detector components on it. This way the operator keeps their fingers away from any electrical connections (including the earth screen) when using the probe.
