If you do not have a laptop, you can find the approximate skew
for your location using the map below.

When to Change the Skew
In general, if your LNB's skew is set to within ± 8º of the ideal
skew for your location, the antenna should continue to provide
good satellite TV reception. However, if you travel to a location
in which your LNB's skew differs by 9º or more, or if reception
degrades the further you travel, you should readjust the LNB's
skew for your new location.
Example: If you traveled from El Salvador to Acapulco along the
coast, you wouldn't need to change the skew, since the correct
skew is 66º for both locations. Even if you continued traveling
north to Cabo San Lucas, you should still have good satellite TV
reception, since the correct skew is 63º, a 3º difference. However,
if you traveled all the way to San Diego, where the correct skew
is 54º, a 12º difference, you might then need to readjust the skew
to enjoy satellite TV reception.
