"I need a special antenna to overcome triple pane uv glass and 1 mile to

Search says 2.4 - 5.8 GHz is involved. A dish has no rear radiation. Its
directivity and gain are proportional to its size and the size is
reasonable since the wavelength is in cm , less than 5 inches.

Depending on frequency and efficiency, a 6-ft dish may give more than 20
dBi gain.

Placement of the dish inside and close to the window may be convenient
for connection and obviates wind-loading. Jam up to the window may
screen the room for much of the possible reflection. Sceens could be
used to deflect other reflections.

High gain may overcome high transmission loss. It`s standard procedure
on microwave paths.
