Making a Parabolic Dish
out of Aluminum Foil
1. Three layers of aluminum
foil were folded on top of each
other to form a square and
then placed on a soft surface
(here: carpet).
2. A smooth ball (also obtained
from my daughter’s stash
of toys) is rolled in a spiral
fashion on the surface of the
aluminum foil starting from
the center and moving to the
outside in order to form a para-
bolic shape.
3. Next the curved aluminum
foil is secured to the antenna
mount. It’s a good idea to do
this on calm days otherwise
the reflector could blow away
in the wind.
