It looks like your electric and cable lines are underground
in that neighborhood. That is good. I guess there is no
restriction on towers. That is also good. I think you have
hit upon the perfect city location! It's good to be in the
center of a development, far from overhead power lines.
I run 1500 watts to a tribander at 50 feet in a neighborhood
like that. I've been here for 29 years now, and neighbors
have come and gone. I've had some complaints, but not many.
Most relate to telephone interference. I just give them a
cheap rfi-resistant phone, and that usually solves the
problem. I don't have any problems in my own house, so I
expect that the neighbors are ok too, but I don't go out and
ask them. Almost all of the complaints have come from within
a 100 yard radius.
An even more serious question these days is how much rfi are
the neighbors going to generate? A bad plasma TV, digital
power supply, or "smart" battery charger can wreak havoc on
the hf bands.
