I don't know if others' experience is similar to mine, but I have had a lot 
of trouble with Jones Plugs going "flakey."  Both new and surplus plugs 
seem to have a tendency, in my rotator disconnect panel, to go intermittent 
on one or more conductor, causing erratic rotator operation or indicator 
function.  I have coped, for the most part by using Caig ProGold to improve 
the connection quality, but for this reason I am going to try another 
approach on my next antenna switch -- I am going to use an 8-pin DIN plug 
and panel-mount socket.  To my surprise, these little plug/socket 
combinations have contacts rated at 1 Amp at ~100 volts DC, which should be 
plenty for my TopTen relay switchboxes that draw only about 30 ma. per 
relay.  They are also a lot more compact than the Jones plugs, and it is a 
lot easier to drill a 1/2" round hole than a rectangular one.  I've never 
heard of anyone else using these in this service, so only time will tell if 
the plug and socket are adequately durable.
