[TowerTalk] Electrical Box Enclosure attached to ground rod?

[Tony]

All,

About to install ICE lightning arrestors on three coax runs as well as 
the rotator cable and could use some advise. I'd like to use a small 
electrical enclosure bolted directly to a 10 foot ground rod with 2 feet 
of the rod left above ground.

It would be ideal to have the box grounded directly to the rod via 
mounting hardware, but I'm not sure if that's the best approach. Does 
anyone know of an enclosure made specifically for mounting onto a pole 
or ground rod?
