PVC pipe doesn't cut it out here in the wilderness!
When we first laid our LAN and power cables between the house and the antenna on the hill for our rural net connection, we just had them naked and hammered in to trees with U-nails through the forest area, then held overhead on some strong fencing wire across the open areas. It wasn't long before the cables became worn and chewed, so we decided to lay the whole distance on the ground within a strong PVC pipe. This worked very well for a year or more, but in the last few weeks connectivity problems have begun again! I thought the problem must be due to the various cable joins at the ends and at the hub at the mid-point, but after checking, re-checking and even re-soldering them all, the problems remained :-( I could tell by the fact that I could connect without trouble from the mid-way hub, that the problem must be in the first hundred metre segment between the house and the mid-point, but I couldn't figure out where the problem was. It was Beth who eventually found the problem; after carefully examining the PVC pipe through the thickest part of the swamp she discovered that some animal has chewed many holes right through it exposing and chewing the cables within! It seems from the damage that whatever animal this is doesn't like to leave the thick cover of the forest and swamp, because there's no damage at all in the open areas or even under the house. It looks like we're going to have to use metal pipe for the fifty or so metres of forest and swamp!
It's not just me with these problems though, even Google have trouble protecting their cables under the sea from shark bites.
