Similar to Clay's rig, but I use $8.95 Home Depot clear plastic-clad bicycle
cable locks over the branches, with stainless links through with the antenna
rope runs. Easy to raise and lower halyard if required, as well as antenna
line. Tree likes the plastic coating, XYL likes the fact tree limb won't be
abraded, and I like the idea tree limb will not grow around the plastic, so in
five years I'll still be able to haul it down.
