imho think POTS wiring and remote power. You can buy and deploy shielded
pair (usually 2 pairs minimum) POTS wire for industrial use. It will
likely outperform RG58 in all mechanical and chemical aspects. Besides,
with RG58 and long cable runs you will need to match the ends for higher
data speeds and that is hard (PIC can't drive 100 ohms properly without
help - but it can drive 600 ohms or 1200 ohms ;-).
