[Elecraft] Very Dissatisfied With Elecraft Support

[Don Wilhelm]

Jon,

A proper RF Probe is usable up to 500 MHz and beyond.
If you are going to use an RF Probe at VHF and UHF bands, then it will 
need to be shielded from stray radiation.  In your situation, you will 
only be using it up to 22 MHz, and shielding it is not necessary.  As 
has been said, if you want to enclose it in something, just use whatever 
you have available, or simply wrap it with tape.  No enclosure is needed 
as long as you do not contact the probe parts while doing a measurement.

Hopefully that provides some reasons for the differences of opinion you 
see on the websites - it all depends on the frequency and other 
conditions where you will be using it.

73,
