[Boatanchors] Questions on the Heath HN-31 Cantenna

[Doug Hensley]

Heath listed a part in the small Bud box on top the Cantenna as part number 56-26, Crystal Diode, Brown-White-Brown (191).  The reference or two I have found was that this is a 1N191 90 PIV 5mA Germanium.   Is there a modern substitute for this that improves on the diode or is finding an original still the best choice?


A related question: a BNC jack would be easier for me to work with rather than the RCA jack when measuring voltage.  Can a "devil's advocate" suggest an obvious reason why not?


Thanks in advance for any suggestions.
