Everyone who's ever had a connector cause a problem wants to say "there 
must be a better way", and of course, if you're buying millions of 
connectors per year, there usually is.

Sooner or later, that "better way" does get into the surplus market 
where thrifty hams feed.

Most HF applications would be adequately served by dual banana plugs, 
powerpole, or weatherproof trailer connectors, as long as they could 
handle the voltage and current (which might rule out the latter, which 
are, after all, designed for 12VDC)

The "impedance bump" such as it is, from the length of a 1-2" banana 
jack and plug isn't going to be a big deal, other than showing up on a 
TDR plot.

Maybe, just maybe, there is something to be said for "continuous shield 
integrity" for coax connectors.
