1/2-inch rebar with plastic pipe slipped over. When the project is over, use a "hickey" to bend into a cane-handle (inverted J) shape and drive into the soil a few inches (they can later be found with metal detectors--if your mapping is good enough to get you within a meter or so. There is a real danger of injury and lawsuits. Industry-standard high-visibility hard plastic caps are available (Forestry Suppliers), but I prefer the (white PVC) plastic pipe, which increases visibility and safety for people and animals. The biggest downside is weight if you have to pack them in; they need to be long enough for solid anchoring and tall enough to support the pipe. Burying plastic with a T and nipples to prevent easy extraction might be a reasonable alternative. I wish a comparable plastic alternative were made. Steel will rust in time.
Buried antennas cost more, and require some time to locate, but that way you can cut temporary stakes in the field and flag. The burial can be impossible on some sites. For what it's worth . . .
