You'll be worried with the RFI on 232C links which we had.
So last year, we connected 5stations by optical fiber line at 
KH0AM. The maximum length of this opt. fiber line might be 
over 1000ft or so. They are bit expensive but more reliable/
RFI free than copper conducter cable.

I heard that K5NA/2 has the source of the opt. fiber link.
But now he might be busy for moving to TX.
