Scott,
*Real* RS-232 ports (those which comply with the +/- 25 volt at the
driver) would easily drive that 150 foot distance, but the PC based
drivers and receivers are not likely to work reliably because the
voltage swing is insufficient to guarantee at least +/- 3 volts of swing
at the receiver.
The other limiting factor is the capacitance between conductors in the
cable - that distorts the waveform. It might work if you invest in
good quality cable and work with slower baud rates.
I would think the loss through 150 feet of LMR400 would be low enough to
be practical and allow the KPA500 to live in the shack.

My tower and garden shed are about 150 feet away. I have LMR400 buried inside
some PEX pipe. Would like to use the KAT500 inside the shed...not sure how
well a serial connection that distance would work!
