Both NFPA 70 (the National Electrical Code) and NFPA 780 (the Lightning Protection Code) have strict requirements for wire sizes and connection methods. Neither grounding systems nor lightning protection systems may use a soldered connection in the circuit. Perhaps your best course of action is to understand the Code requirements, and construct your system accordingly. Keep in mind the fact that your insurance underwriter may deny any and all claims for damages due to lightning, if your system was constructed in a manner inconsistent with the applicable codes. 73, Eric Lemmon WB6FLY You dont need any solder joints with type K or L soft copper. The material comes is 60 or 100 foot rolls and you just flatten the ends and drill holes for mounting bolts and star washers. ½ inch soft copper is actually 5/8 inch OD and makes a great conductor. The material comes in size up to 2 inch but that gets pretty expensive. This pipe is designed to be buried in the ground so you can be assured it will stand up just fine outdoors. One caution is to anchor it down, swinging in the wind will cause it to break due to repeated flexing. All the normal bend radius for electrical conductors should be observed as lightning does not like to make sharp corners. Jack K6YC
