Suggestion: I see RF millivoltmeters from names like Boonton and
Millivac at ham swap meets. Most will drop down into the microvolt range
at the bottom, and up to 3 volts at the top. Both have available 100:1
dividers for their probes to increase that range even further.
Would it not be simpler just to chase one of these meters? It'd
probably be a lot more versatile than a basic RF probe.
FWIW: The Motorola S1339 meter is nothing more than a Boonton with
a different front panel.
Keep the peace(es).
