I'm working on the ground field of my new towerette (40' Rohn 25). The tower is 
and is about 70 feet from my house, and the radio room (2nd floor shack).
Following some of the dialog here and that in the recent QST magazines, I'm 
at the tower, with multiple runs of 8' ground rods every 16', connected by 
bare, buried #4.

My service entrance is on the far opposite side of my house from the shack. A 
single point
ground is not therefore easily accomplishable. In order to tie the shack 
entrance (for coax
and rotor cable runs) to the service entrance, I'm going to work my way around 
the back of the
house, with more 8'
ground rods every 16'  connected with buried #4 until I can tie in the service 

I have several questions:

1) Should I tie the ground ring around the house to that at the tower base?
      I understand that it will be (poorly!) via the coax shield, but I seem to
      remember reading that if the tower is a distance from the house,
      that it was not always desirable to tie the tower ground field into
      the ground ring around the house.

2)   In accomplishing the ground ring around the house, to tie the
      radio "service entrance" to the house service entrance,
      I'm going to encounter a section of direct burial Romex that
      is only about 6" under the surface. It's there to power the septic sump

      How should I cross that run? There's really no way to go "around"
      it. Even though they'll cross at right angles, I'm concerned about
      inducing voltage into that romex run, and therefore into the house.
      Should I be concerned?

Thanks one and all....
