The S column is a relative signal strength subjective receive assessment
based on using a 1/4 wave 20" whip on the roof of your car.  This antenna
is about the best for satellite mobile unless you want to carry a beam.

                                                SIG RECEIVE RANGE
USING A 20" WHIP VERTICAL WHIP ON YOUR ROOF:    --- ------------------
As a rough approximation consider this table     9  Horizon to Horizon
which  I have subjectively  determined after     8  5  deg and above
3 months  of daily monitoring. Home stations     7  10 deg and above
with 50' of RG 8  should subtract abt 3 from     6  15 deg and above
the signals and 5/8  or dual band, or "gain"     5  20 deg and above
antennas  should also subtract about 2.          4  25 deg and above
                                                 3  30 deg and above
There are lots of satelltes lots of times        2  3 ele beam
throughout the day.  If you are stuck in your    1  6 ele beam required
car, enjoy them!

MOBILE TRACKING DATA:
The AZ and frequencies of satellites in view are transmitted to
mobiles once a minute on the local APRS 144.39 frequency if there is
a local APRSDATA server in your area.  Also a satellite schedule
for the next 80 minutes is transmitted once every 10 minutes.  If you
have the Kenwood D7 or D700 integrated APRS radio, this information
will be flashed on your front panel or spoken to you so you can't miss
it...  See SAT-INFO web page below:
