[Lowfer] Report and Order

[Eric Smith]

100m from transmission lines?  That's a whole block.  This must mean
high voltage long haul lines, not the distribution lines that run
along many city streets?  For many folks it would be impossible to get
100m from these distribution lines if the transmitter has to be at
your house (not portable).

So must mean the high voltage long haul lines?  Otherwise I wouldn't
suggest the 100m ..
