[Elecraft] UHF connectors [was: Array Solutions Lightning Arrestor]

[Wes Stewart]

I haven't been following this too closely but...

In a Zo matched system, e.g. network analyzer, reflected power is burned up in 
the instrument.  So "mismatch loss" is real loss and shows up in s21.   Think of 
measuring a crystal filter.  The crystals can be very low loss but the insertion 
loss is high out of the passband because the filter is a huge mismatch.

I agree however with the conclusion.
