a real high resistance from he center conductor to ground. Something in the order of 2-4 Megs would be so high that the signal/receiver would never see it. Heathkit did this in their little remote antenna switch that switched antennas with a control voltage on the coax. This same approach should work with your induced voltage on your yagi. Approaching storms produce a high charge on the antenna. If I unplug my coax from the antenna switch, the charge is so high that it jumps from the center conductor to the shield of my PL-259. In other words, it is quite a build up in static charge. I have 2 Meg ohm, 2 watt resistors bypassing each of my 160M verticals to ground. This bleeds off the static charge nicely. Something like this should work for your system too. I would put between a 2 Meg ohm-4 Meg ohm resistor across the feed point of your antenna to ground. Two watts should be more than adequate. I have only done this on my verticals and not my yagis. The Force 12 driven elements are above ground however it should work there too. This may be a fix for the problem and not the solution to the problem. 73, Charlie, W0YG..>> -------------------------------------------- Force12Talk mailing list provided as a service by Force 12 Antennas, Inc.
