[MRCA] remote antenna conduit?

[W2HX]

Boy, I feel dumb. That is, of course, a better idea than soldering a multi-pin connector under the trees! The rigid PVC won't work because I live on a hill and also there is lots of bedrock that I will need to route around and avoid. Will have to be flexible.

You could pull it the other way and do the soldering in your shack. For control signals the barrier block is fine. I like rigid PVC, it's not that expensive. 
Consider running heliax, less loss and more stable.
