[RFI] Ladder Line and RFI/Noise

[Rick Karlquist]

I have 850 feet of 450 ohm open wire line.  If I disconnect
the antenna, the noise drops way down, indicating that the line
is not picking up much noise on its own.  It would be unlikely that
a noise source would produce more signal due to line pickup than
the amount of signal it induces in my 90 ft vertical.  The open wire line
runs within 5 feet of one of my houses and 25 feet of another of my
houses.
