If you have a swale in your property, like I did.
at the low point, dig a hole, install a plastic sump pit liner from home depot
fill it with gravel (this is called a dry well)
Then install a DOUBLE TEE or sometimes called a 4-WAY, so condensation drips
onto gravel.
The top fitting of the Double Tee, put in a plug, Can be used for inspection.
If this swale fills with water...disregard...
Also I think a lot would depend on the coax and wire coating you use.
Even after the heaviest rains, I never detected any wet coax or wires.

What are the thoughts pertaining to condensation in the pvc pipe. Do you
drill holes in the pvc pipe at the low points or just let the cables set in
water? Thanks

My experience:
Several years a go I put a big plastic pipe (8inch dia) under the house to
the towers.
There are several coax'es 7/8 in them ,and a lot of controlwires.Those
pipes
came out at
the towers and coax'es en control wires (rotor -switching) moving up at
thetower.
2 years ago I chanced the whole antenna system and placed kabinets at each
tower.
When I toke all the cabels out the pipes most off controlwires where
strangled around coax
and others wires.A lot off work.
I have now taped 2 control wires at 1 coax and vica versa.Yes I had some
spare coax and controlwires
so putt it all in.I'f something go wrong a have another control cable.And
if something wrong with a
coax (I dont think for the first 20years) I can easely checked with the
labels and remove them easely.
for pull rope I use a small SS cable.Making a plan off all wires and label
them.Very easy even in the dark
O yes "I have lights in the cabinets"
