»liveSCAN directional antenna kit
Optional Accessories

The SNYPER-3G Spectrum is a high performance cellular signal and network analyser
for all 2G and 3G networks, with a host of important features for the busy engineer
and installer.
The SNYPER-3G Spectrum can perform a number of different functions to determine
optimum antenna placement and direction, performance of existing installations of
network operator. As an example, the SNYPER-3G Spectrum can determine the
strength of a particular network and the optimum direction of the antenna using the
liveSCAN feature.
