[Elecraft] UHF CONNECTORS

This discussion is getting VERY far afield from the topic of connectors 
used on HF equipment.

However, the analysis in this tome is rather flawed, which renders the 
conclusion the author draws misleading at best. The flaw is that the 
author measures the impedance bump at the connector, computes a quantity 
called "mismatch loss" that is fictional in most ham antenna systems, 
and decides that there is massive power loss in the system.

Most of us who do anything serious on 2M and above use BNCs and Ns at 
those frequencies. But I've visited several big contesting stations 
built by very good engineers, and UHFconnectors are the weapon of choice.
