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 radio reception, Hi-Fi in general, cable and DSL modems, etc. Your situation would make me nervous. Even 100W levels might interfere with your neighbor's electronics. Sorry, don't mean to rain on your parade, but this could be problematic for you. I guess it wouldn't hurt to try... 73, David K3KY _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
