Topband: COAX CABLE

[Guy Olinger K2AV]

One reason to use RG6 for burying, is that it is a lot easier to bury
across lawns, etc.  You can push it into a notch (as opposed to a
trench) and just step on it.  It's out of sight, and undetectable
after the next rain and lawn mowing.

I discovered about 4 years ago that the cable TV companies no longer use hardline-everything in the cities has apparently gone fibre optic.  In many cases, the companies have reels and reels of both direct burial flooded hardline and unjacketed Aluminflex or similar for overhead runs.  As there is no market for all this cable in my area, the only option is recycling, and because it is not pure copper or pure aluminum the cable is considered "dirty wire" and fetches something like $.20 per lb.

At some 375 lbs per spool, the total cost was a bit more than buying 1000 ft of good RG-6 and some connectors, and the loss is infinitely better.  In addition, critters don't try to chew on it and if something happens to break the line a splice is easy to make.

An upside-down plastic bottle is the weatherproofing (thank VE1ZZ for these ideas).  At 1.8 mhz there is no mismatch measureable nor is the loss on my three 600 ft runs of any consequence.
