Capacitive Coupling
An ideal place to use capacitive coupling in an individually metered building is directly
after the meter bank. This reduces the attenuation that the meters cause to the signal,
and, in most cases, the local utility will not need to be involved. In some areas, this is not
possible due to the fact that you cannot access the area because of a conduit or other
enclosure.
In most cases, capacitive coupling in an individually metered building will have to be done
AFTER the meter bank. This is best done off of the house (or common or landlord) meter
if it is located in the same room or on the same meter bank as the individual unit meters.
In this case, the RF signal will have to penetrate through the house or common meter,
then through a SECOND meter to get to the individual units. For this reason, inductive
coupling is the better way to install Powerline MU in an individually metered
building.
