why wait for vacancy.. the lots in my neighborhood are 50 feet wide, so 
the houses on either side are basically 100 ft (call it about 30 meters) 
apart. If I load up the two houses on either side as the two sides of a 
dipole, accounting for the large capacitance (the wiring in the house 
looks like a big ball at RF), I should be almost right on for 80m.

There is a little challenge with the balun, since we have underground 
utilities.  If I lived in an area with overhead lines, you could just 
throw a big core around the power drop and transformer couple it as a 
common mode signal.  Think of it as narrowband over powerline  (NPL).

I confess there *may* be some RFI issues with this strategy, but at 
least it's visually stealthy.
