Does anyone have a good idea of minimum bending radius for the 1/2 inch cable TV hardline? I have been

Like Andrew LDF Heliax? 5" is the min bending radius..
The thing to remember is not so much the bend radius, but, rather, you
only get to bend it once. Each time you bend it, it work hardens the
copper a bit, leading to cracks, etc.
Also, if you're going to bend it that tight, you need some sort of
mandrel or bending jig to support it. Think of bending copper tubing or
electrical conduit. (in fact, a conduit bender might work real well for
