[TowerTalk] Solid copper ground wire supplier

[Tony]

All,

I need ground wire for my tower and was wondering if someone could 
recommend an online supplier? The TT archives suggest heavy gauge solid 
copper and that's what I intend to install. The local stores I've 
checked have stranded only. One supplier suggested tinned solid to 
extend the life of the wire which, he says, adds pennies to the price. 
It sounds like a good idea, but I've never heard anyone mention tinned 
wire for tower grounding before.
