Hi Chuck,

The lawn staples are from DX Engineering (as was the beautiful radial plate
with bulkhead coax connector).
They are about 6 inches long, a rectangle, maybe 1 inch wide, and heavy
enough that you can pound them in with a hammer, as long as your soil isn't
concrete. Sold in packages of 10 or 20, I think. Quite reasonably priced. I
only have one staple per wire now (doing it in the middle of winter made me
move quickly between ice and mud patches). I'll put down a staple every 10'
or so when things dry out.

Google DX Engineering and you will find there web site. From there it's
pretty easy to find stuff.
