This sounds like an excellent application for star quad, and a good
endorsement for permanent outdoors use. Most of my experience with
star quad is with the Canare product range, and it is a very well-
made cable (as are all of Canare's cables). I usually spec it for on-
stage mic cables in touring PA systems, where its rugged construction
is a benefit (after all, it is likely to get stepped on, jumped on,
danced on, twisted viciously by idiot singers who like to play
bullroarer with the microphone, rolled over by roadcases, immersed in
beer-soaked carpet and so on). Plus, with two inner conductors per
pin, there is a bit of redundancy if one of the inner conductors gets
damaged. But it's a PITA to assemble, IMO.
You are monitoring ultrasound... what frequencies and bandwidth are
you working in? And what lengths/distances are you using?

Interesting observation...
BTW, I'd like to know what it is that makes cables so attractive to
gnawing rodents; it's a problem that's been around for as long as
there have been cables.
And rodents.
Together.
