It's a more echonomical and reliable alternative to BPL that doesn't polute
the ham bands.
Unfortunately, Michigan, which is where I live, is in deep financial doggie
do. They are going for the big federal grants to bring in money and that
includes BPL. We don't need BPL in the bottom 2/3rds of the lowe peninsula
as most of it is heavily populated and most of that is served by high speed
cable, DSL, or WiMax, but that is the area I see as likely to get BPL if the
state gets their way. Those are the areas where the pilot projects are being
run. It is also the area with the most hams to have interference and to
I do have to admit that from what I've seen, BPL is getting better and most
of the groups are willing to work with the hams. Not all but many. OTOH Most
of the power company ventures into BPL Internet service have closed down
incuded the big one in Cincinatti.
As for antennas: The better the higher the gain the farther we can hear BPL
and the farther away we can interfere with it.
In the early days were the systems were highly susceptable to ingress I
would have had a strong enough signal to shut down a system over a mile
away. My 75 meter, half wave, center fed sloper on Europe is less than 75'
from the pwer line.
