Is the TE-22 and 25 what you're using to drive ground rods also, Mike???
Yes,Dave, it is!. I'd personally use the TE-25 though, it's more rugged than the 22. I used the 25 at a recent "RF Ground Driving" stint at a local Ham's Shack. I told the older guys to put the club hammers away. After I drove a series of Galv rods into the ground, with little or no effort at all, there was much head scratching amongst the congregation of fellow Hams. Followed by "Can I borrow that?".
