Although the PTFE insulator is great, silver plated connectors do not 
stand up well around here if they are going to be out in the elements.  
Even nickle plated will start turning green in less than a year.  We may 
be 200 miles plus down wind from the manufacturing area on the South end 
of Lake Michigan and Chicago, but we sure do get the results from it.

I bought from DXE 'cuz they're small compared to Mouser, they're hams, and they have the best deal on the coax I was looking for (DXE400MAX-500).

Most of the feed lines here are either LMR-600 or double shield 8X,  I 
much prefer 8X to 58 as it's more rugged and flexible.  It'll also take 
the legal limit on 40 and 20 if the SWR is low.  It doesn't work well on 
75 if you want to cover much of the band.  The same is true for 160 plus 
the loss due to Resistance is quite high on 160.

I've had very poor luck with the UF versions of the LMR cables because 
of the jacket material.  The regular LMR cables are great.  Except for 
the LMR600 I use all crimp connectors with the center pin soldered.

I tried the 240 versions but they were just too fragile.  Stiff and 
difficult to install connectors.
