I am about to pour concrete for the base of my HDX589 tower. I am going to go
with a Ufer ground as well as the Polyphaser recommended eight 75' radials with
multiple ground rods (8' rods every 16'). Location is on top of a 1600' ridge
in WV and lightning is a very real concern. My QRZ web page gives a feel for
the location.
To build the Ufer ground, I am thinking about connecting a single bare 2/0
stranded copper wire to the rebar. Questions:
1) is one enough?
2) how do I properly connect the copper to the rebar? Is exothermic weld the
only way? Any problem with dissimilar metals?
3) how should the copper exit the base slab - above grade or below grade?
Also, seems that copper strap is the preferred ground material for connecting
rods together. Will 0.032" thick strap have significantly better longevity than
0.022" strap? I am refering to the strap sold by Georgia Copper. Copper is
expensive and I don't want to invest in copper that won't add any value to my
installation.
Where can I find exothermic weld products to connect copper strap to 5/8"
copper clad ground rods? I am exhausted reading Harger, Erico, Terraweld info,
and can only find wire-to-ground rod products, no strap-to-rod products.
