Dick,
My fullsize 4el 40 with cool dry air wil arc several inches from coax tip
to ground from static. With the Morgan M303 inline... Nothing. This was
also very apparent on the SDR (Flex) screen from what looked like lightning
static crashes to.. Nothing. In that respect, they did exactly what they
claimed.
