[TowerTalk] Grounding HDX-555

[Gene Smar]

Patrick:

     I would not bury a mechanical ground clamp.  It can't easily be checked 
and retightened each year.  I would use a longer ground rod and leave six 
inches or so above ground and apply the clamp there.  A welded connection 
such as Cadweld can be buried and forgotten.  My 132 feet or so of #2 solid 
ground wire is attached to 12 copper ground rods with that method.
