Appendix E: Listing of Antenna Parameters
The SIR 4000 comes with preloaded setups to fit the system’s data collection parameters and filters to the
most commonly used, currently available GSSI antennas. Settings for additional antennae are also
provided below to assist you in creating a setup for an older or specialized antenna. Please note that these
are only generalized setups, and it may be necessary to alter these to your particular situation. For
example, deeper penetration can be set by increasing the range in the Radar menu during setup. Please
note that this is not an exhaustive list and you should consult the antenna documentation saved on the
Manual CD Compendium or on the GSSI Support Website:
