When the electrical installation of the cable bridge when the copper grounding wire
the above in turn according to the wiring tube / copper nose diameter selection Multi-strand, 2 × 15 with Φ5 ~ 6mm, 4 × 15mm with Φ8mm, this is in accordance with the cross-section and the number of algorithms
I used two wireless router, open, pass 2 km, one by one, dual antenna, of course, more better, there are directional antenna approach to see the next, I use the smallest satellite dish to do the reflection is the board, U Face
The simplest way is 20 to 30% larger than the outside diameter of the conduit / copper nose
