Topband: Common-mode noise/long buried feedline runs

[Les Kalmus]

"then you might want to suppress common mode 
leaving the shack AFTER the cables pass through the entrance 
grounding panel (we all are safe and have them, right?) on 
the way out to the antennas."

This snippet from the previous post raises a related question. I am building a new house to replace the 105 year old farmhouse we now live in. The existing cable runs, 3 hardline, 2 control cables and 110VAC to the tower will be retained and will pass through the new concrete foundation.

Is it best to provide the entrance grounding panel outside or inside of the foundation? I think inside will be more convenient to work on and require a smaller opening(s) in the wall but outside directly to the perimeter ground sounds like the way to go.

In either case, can someone suggest the most professional way to do this? Esthetics (XYL) are important. The current install comes through the existing foundation wall below grade and is invisible outside but is far from ideal as far as grounding as I would have liked it.

By the way, if anyone is interested, the farmhouse, which was renovated about 5 1/2 years ago and is in good shape but a little small for our needs is anyone's for the taking during March. Located south of Kingston, NY.
