Hi, Jim- Remember, when you transmit, those radials are radiating. Worst case, you might even get arcing from any unlucky voltage points along the 'radials' depending on power level and the actual lengths. And those wires are in your neighbors' basements? Yikes! They could possibly tear up AM

I just measured the length of 4 two conductor cables  the water Co.  abandoned when they went to walk-by metering.    My basement has access to cables running to 3 other condo basements which I will use.   Using measured capacitance between the two conductors  of my cable ( 24pf / ft.) it was
