Get rid of fluorescent strip lights from your house, only QRM generators for
radio amateurs.
It seems MINIWHIP antennas work better the higher they are installed above
ground which makes me think that the cable connecting the probe to the RX is
in fact the REAL antenna. !!!!!!!!!!!!!!!
A probe antenna should work equally well at ground level in the clear as in
an elevated position.
