The following website describes the best way to install a random wire or
inverted-L antenna to minimize the noise from domestic sources. The
vertical downlead wire should be located a considerable distance from
the house (at least 20-ft). This is where the ground connection is made
at the bottom of the downlead and the matching transformer. Coax is run
on/in the ground from the transformer, back to the receiver in the house.

Hello:

For a receiving only application:

Any opinions as to how far away from a house (with the normal compliment of
PC's, broadband, etc. noise producers)
the vertical leg of an inverted-L antenna should be so as not to pick up any
meaningful amounts of household electrical noise ?

I imagine that these fields diminish very, very quickly with distance ?

The reason I'm asking is that the easiest thing for me, by far, would be to
run the vertical leg up the outside of the house, perhaps on 6 inch
standoffs. The high horiz. leg would lead away from the house.

I realize that the further the better, but would 6" be "enough" ?

Any thoughts on ?
