antenna for high-performance GSM/PCN/UMTS operation.
The Wallen Tri-Com offers high antenna performance
for mobile phones, to minimise call dropouts. It
provides an efficient in-vehicle alternative or
replacement for any conventional antenna.
Switch on your phone
and Tri-Com will automatically operate with GSM
or PCN or UMTS networks, enabling you to use (and
swap between) all types of cellphone without having
to change the car antenna system. It also operates
with the new breed of multi-band cellphones. If
you use a global positioning system (perhaps with
a PDA for vehicle navigation or other applications),
then you can order Tri-Com with an active 26dB GPS
Tri-Com is designed
for optimum performance, featuring a neat transducer
system housed in a flexible moulding. This makes
it supremely cost effective compared to alternative
antennae and there is no need to drill holes in
the vehicle bodywork when installing. With no external
parts, Tri-Com avoids wind noise, drag and the danger
of vandalism associated with conventional antennae.
As a result, Tri-Com
is an ideal antenna for cabriolets and GRP vehicles.
The design is ground plane independent and can be
orientated vertically, horizontally or at a convenient
angle on any fixed (non-opening) window in a vehicle.
Ideally, the Tri-Com is best positioned on the windscreen
behind the interior mirror or on the rear window,
to provide an unobtrusive yet powerful antenna.
