Hi Phil:
Two thoughts on your question. First it sound like your putting in the ground rod for RF grounding reasons. Ground rods are very poor RF grounds. Grounds rods are for lighting and electrical safety not RF. If you want a good RF ground plus electrical protection ground putting in a ground rod plus as many buried radials of what ever length you can manage will do the job much better. Second, I have 6 ground rods in my tower installation. The ground here is rocky also, which made putting them in not something I looked forward to. In the end I used an electric jack hammer to put them in. It had a cup adapter in place of the normal bit. I started the rod by hand with a big hammer and then muscled the electric jack hammer up and finished the job. The hardest part was lifting the jack hammer up to reach the top of the ground rod. This is a lot easier if you have some help. The jack hammer belonged to a friend but I'm sure that a large rental store should have them. -- John Passaneau, W3JXP Penn State University "Northern Lights" wrote in message news:1069183285.115652@rh9cache2... I have a mundane question. Does anyone have suggestions for installing ground rods in rocky soil? The topsoil on my property tends to be very shallow, at times only 12 in. deep. I would rather use earth ground and not go the route of an artificial ground. I think I know the answer to my question but wanted to see if anyone out there had a silver bullet solution. Phil, K4NE |
