[RFI] Lightning Arresters

[Mike Martin]

Jim,
Not exactly, that is more the indication that the U-S can't detect the source for anyone of many reasons. I'm not implying it can't be a LA.
The sensitivity of that unit is a big factor and since you're dealing with line of site it possible the source isn't detected because it can't see it. The freq your using is a good frequency to use but make sure its your source and not just a source.
