[OKDXA] Plan C - NOT placing coax in plastic pipe

Yokay... We're talking RX only and that simplifies the situation as we
can think about RG-59 and 3/4" PVC. If you run the coax elevated you're
looking at a vertical support every 40' to 50' and on a run that long...
Especially if it isn't a straight line... That would require a fair
amount of tension on the coax to keep it mostly horizontal. The vertical
supports would tend to be pulled from side to side as they zig and zag.
On 10' PVC you'd want about 2' in the ground lest some of them try to
fall over. I'd be concerned about how much pull the coax could take, ice
storms, fallen branches, etc. Your net height would be in the 8' range
with less between the vertical supports and anything that hangs less
than 7' up makes me nervous. I'm thinking high maintenance with enough
visual impact to make an elevated run worth reconsidering.
Not having seen the property but being familiar with the joys of digging
a trench near trees and cutting roots to do it, I'd be very tempted to
run PVC on the ground through the wooded areas and shallow trench it
anywhere that might see a lawn mower. Next time you're at the handy guy
store price out the bundle price on 3/4" gray PVC conduit. Generally
they'll have a 10 stick bundle discounted from the usual per-piece price
and one end is flared so you won't need couplers. If it's on the ground
there's not much need to glue it and having the pieces jam-fit together
will simplify your life when it's time to thread the coax through the
pipe. If you're concerned about the pipe being kicked around or
otherwise moved, once it's wired and ready to RX there's nothing that
says you can't spike standard half-round electrical clamps to the ground
with large nails to stabilize the run. As for water intrusion, shouldn't
be too hard to figure out where the low spots are and drill a weep hole
or three so it can drain. Dig a shallow pit under the weep hole(s) and
bring it back up to level with some gravel to reduce the risk of
standing water until the gravel packs up with organic debris. I'm
assuming this area does not see livestock, ATV's or dirt bikes. (?)
The other advantage to laying the PVC on the ground is that if you
decide to rip it out in the future you're looking at an afternoon job
instead of a weekend job. If it looks funky, rake some dirt over the
pipe or just wait. Mother nature will provide plenty of ground cover and
the medium gray tends to blend. If all you need is a single run of coax,
3/4" PVC is big enough for RG-59 through RG-213.
BTW: In the fall poison ivy has a reddish-brown stem. Look for a fairly
sturdy vine growing in shaded areas with three leaf clusters. It loves
to climb trees and wiggle around inside bushes. The leaves are teardrop
shaped and unique in that no two leaves are exactly alike. Some will
have a notch on one side, both sides, smooth edge, serrated edge, each
leaf is unique unlike other plants where all the leaves are identical.
I've been fighting poison ivy on the north side of the house for several
years and this year the soil is going to get nuked with a broad spectrum
herbicide as soon as I pull the plants I want to save. Damn stuff will
light me up about 3-4 days after exposure so whenever I think I missed
the bullet... Fooled again. Got me good twice this summer. ;)
