Two inch wide .030 inch thick copper strap for radio ground. About 15 feet long. This is ten times as thick as the stuff that Defender sells, but only two inched wide. The thin stuff will corrode away quickly and you will be replacing it frequently. This stuff lasts forever. Surface area is what counts for HF radio, thickness counts for longevity.
Defender price: $1.34 a foot. My price: $30.00 for the full length which comes to 2.00 a foot. Ten times the thickness for less than two times the price but yes, only two inches wide, not three. Actual USPS priority mail shipping to be added to the price.
It's a little dingy from laying around but perfectly good.
