[Boatanchors] Questions on the Heath HN-31 Cantenna

[Jacques Fortin]

Yes, but...
Not all the schottky have a PIV as high as 90V (or more), so beware about the one you choose.

Just put in a Schottky diode.  The calibration, of the circuit in the box, is only relative.

If the BNC works well with your other test equipment, then change the RCA jack to a BNC.

 Subject: [Boatanchors] Questions on the Heath HN-31 Cantenna
   
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.
