That one works FB at up to 1.5MB/sec.  Connected to my LAN in the shack is a 802.11G router with dual antennas.  A simple mag mount collinear on the outside wall provides a local hot spot for up in the house, some 200' - 220' away.  My XYL uses the link to access the internet and my LAN in the shack.  The trouble is, her connectivity on the laptop is poor.  Near a window she gets 2-3 bars of signal (whatever that means) but loses the connection from time-to-time.

Not so much gain with 30 degree beamwidth. Maybe another router in the
house located at a window with an omni antenna inside. Or another router
in the house hooked by wire to the the hamshack LAN.

It may not be so much antenna pattern as attenuation through the house
walls, especially in this house with steel siding.
