The type of wire is not important in bonding applications. The object of bonding is to prevent potential voltages from 2 different grounds. In the event of a lightning strike, you want all grounding systems to be at the same potential. This relates to safety & equipment protection, not RF grounding. Example, if your electrical service ground has a resistance of 3 ohms (NEC requires it to be 4 ohms or less) and your ham station ground is 1 ohm, if lightning strikes the power lines on the next block, the surge coming in the power line to your home will be seeking your ground rod at your home. This surge will not be the full current of the strike, as ohms law is in effect, resistance of the ckt limits the current. If the strike sees your house ground at 3 ohms, but the ham ground is 1 ohm, It will take whatever path it needs to that lower resistance ground, that means thru your radio or any other equipment that has both a electrical ground (3 wire cord) & a ham station ground (antenna system) The bonding between these 2 grounds makes the surge see the low resistance of the combined grounds and greatly lowers the chance it will take a path thru your equipment.

Being up on the second story can present RF-in-the-shack problems if you don't have a very good low inductance path to ground.
