[Antennas] RF Poisoning?

[David Robbins]

Lots of info here: http://www.arrl.org/smart-meters
There are various frequencies, 450Mhz and 900Mhz are common ones but there
were some that were around 3Mhz at one time and others now in 2.4Ghz range.
They are typically only transmitting in response to a remote command, this
could only be once a month if they are only used for meter reading from a
mobile reader, or more frequently if they are in a network where the utility
is using them for active sensing or control of home or business loads.

google for 'smart electric meter frequency' only gives 293k results.

I live where there are "Smart Meters" ... electric utility meters that
transmit electrical usage data to the power company.

First, I don't know exactly how they work so I am guessing a bit.

THE ANTENNA PART - questions
1.  Do the powerlines outside and inside the home or business become
antennas for a LF or HF or VHF or UHF or Microwave signal to-from these
meters?

2.  Typically is this data RF signal "ON" all the time?

3.  Is the RF signal isolated or blocked or "bypassed" with an RF capacitor
to ground so it does not enter the building on which the meter is installed?
