Smoothtalker
large magnetic base antennas include SEMRC205 quad shield low loss co-ax antenna
cable. This cable is a flexible cable with a solid center conductor, four layers
of shielding and has the lowest loss specifications for cable of its diameter
(.205 inches). SEMRC205 quad shield low loss co-ax antenna cable at 15 ft. of
length with a connector on each end has less than 1.8 dB total loss at 850 Mhz,
and less than 3.25 dB total loss at 1920 Mhz.
Smoothtalker
small magnetic base antennas include SEMRC105 dual shield low loss co-ax antenna
cable. This cable is small diameter ultra flexible cable with two layers of
shielding, and has the lowest loss specifications for cable of its diameter
(.105 inches). SEMRC105 dual shield low loss co-ax antenna cable at 15 ft. of
length with a connector on each end has lower loss than RG-58U larger diameter
co-ax cable found on many other cellular antennas.
NOTES:
1-information listed below
shows antenna performance as measured in our laboratory and field antenna performance
in the environment listed. Field performance measurements vary with physical
location and sometimes show increased performace figures and sometimes show
decreased performance figures than those listed below.
2-All Smoothtalker external
antennas are available with either FME female or MCT Female connectors. If a
smoothalker antenna is to be connected to a device or cable with any other type
of RF connector, then an antenna
cable connector adapter will be required.
3-To learn more about how
an external cellantenna designed for use in car, truck, boat or SOHO (small
office or home office) will perform and how to make the right choice of antenna
for the environment where the digital antenna or analog antenna is to be used,
the following technical document is recommended reading: Cellular
Antennas
The
SEM2 series Low Gain dual band antennas are recommended for best performance
and signal range increase in uneven terrain with obstructions. This
includes large cities with tall buildings, wooded areas, mountainous
areas, low lying areas like valleys or canyons etc. This type of antenna
will work best when it is on groundplane (a metal surface like the roof
of a vehicle). If the antenna is to be used when travelling through
different terrain, then this antenna will give best overall performance
and signal reception and transmit range.

The
Sem11 series Medium Gain cellular car and house antenna is a good overall
performing antenna that is both attractive and functional. This antenna
has is best suited to vehicles with obstructions on the roof where some
vertical height is required. The enclosed coil and ergonomic design
impede wind noise and whistle when used on a car or truck travelling
at high speed.

The
Sem26 series High Gain external cellantenna is a dual enclosed coil antenna
that is designed and recommended to be used in any environment that is
reasonably flat and where the cellular base station or transmiter or receiver
is on the horizon or unobstructed. Best signal range will be achieved
when used in flat desert, plains, oceans etc. This antenna has the highest
gain in the 800Mhz cellular band and its radiation pattern will radiate
more accutely towards the horizon when compared with all other Smooth
Talker external antennas. |
