At Contest University in Dayton last week, Frank W3LPL spoke to that issue.
As I recall, the answer was AT LEAST three grounding rods in a circle of
radius 1 rod around the base.  For more protection add additional rods
further out at a distance of about one ground rod.  I would use cadweld and
2 gauge tinned copper wire for connections, except at the tower, where
stainless steel clamps designed for this purpose, from DX Engineering, are

Hello everybody,


I plan to erect the new tower. It would be a 60' + 10' mast on the top.
Currently working on grounding system for station and I came across a lot of
posts and articles.  My initial plan was to bond the tower with the house
grounding system and entrance point, until I have found W8JI article about
grounding station . He says:


"If the tower or antenna is near the house, it is better to bond it in. If
the tower if more than 50 feet away, it might as well be isolated on its own
ground because the impedance will likely be too high to be an effective


In my case the tower would be 170+ feet away from the house. Just looking
for other opinions/thoughts.
