said in rec.radio.scanner: Just a thought here, but did you drill any holes in the pipe to insert the wire into before soldering? My thinking is that if the wire is just soldered to the outside of the pipe (without any other means of holding the wire attached to the pipe,) that should a lightning strike ever happen, the intense heat from the huge amount of electrical discharge may just melt the solder and allow the wire to become detached from the grounding pipe. In the event of a direct lightning strike, the wire, the pipe (the mast and antenna too) will disappear. "Lightning protection" will protect the radio from static buildup from nearby strikes, rain (raindrops carry a charge), etc. Don't *E*V*E*R* think that you or your radio are "protected" against lightning by a flimsy 6 inch thick piece of copper, let alone by a piece of wire, no matter how thick. A lightning bolt is *at least* a few thousand volts and a few thousand amps. (Yes, that's a MILLIONS of watts - for each full strike.) The temperatures approach that of the sun. Not impressed yet? I've seen a well-"protected" commercial broadcast antenna (the gap balls were about a foot in diameter each, grounded by solid rods a few inches in diameter - no mere "wire") turn into a blackened concrete base with 4 holes in it (where the tower legs had been), so don't think that anything you install will do better. If you assume that a direct strike to the antenna will kill you if the cable is still connected to the scanner, you'll live a lot longer. The last thing anyone wants is a link to a newspaper article telling us how some hobbyist died from a lightning strike to his antenna. |
