Antenna inside (-89dBm):

Antenna just outside the window (-84dBm):

Move the antenna 8 feet east for a 9dB signal strength increase (-75dBm
= three green lights (power/Ethernet + two signal "bars") ...

The nice thing about the mounting, is that there is NO attachment to the
house, which makes adjustment trivial (sliding the mounting hooks in the
rain gutter). Even the Ethernet cable goes through pre-existing
screening in attic vents. The whole thing can be removed from the house
without a trace in 20 minutes (10 minutes, if one is young and agile,
which I am neither). It's (reasonably) light-weight (another plus, for
the same personal reasons).
