I have had ALL my tower-to-shack cabling in 2 x 3" PVC conduit buried under
maybe 4" of dirt (acros my side yard in WV) for 5 years. Absolutely NO
problems. To be fair, mine has a very distinct one-way pitch, so water
retention is NOT a problem. This conduit is the stuff used for TV cable
and utility wiring, with thick walls and a silicone lining for easy
cable-pulling.
