[TowerTalk] B olted connections to concrete

[Nick Pair]

No form of connection directly to the concrete will give you any additional radial length or ability to dissipate any currents. You would need a low impedance connection to any( a lot of driveways don't have rebar or mesh reinforcing in them) metallic items in the original pour. Your really out of luck on existing slabs. Prestressed slabs are a whole new category and not really pertinent to this thread but usually have some method of grounding any structural steel contained, and sometime cathodic protection for tendons. Most antenna radials are part of the antenna tuning and therefore need to be a tuned length to be as effective as possible. Again that is another thread that the group may want to rehash again.:-)
  So put that box of concrete anchors away and get out the antenna analyzer to tune radials. Then you can sit back and enjoy your new concrete work!
