Legacy Antenna Pattern Data Archives

Legacy Andrew Antenna Data
Before Andrew Antennas was acquired by CommScope, they widely distributed a set of computer tools to assist microwave systems designers in the use of their products. These tools were released, free of charge, on a CD-ROM and known as the Andrew “Power Tools” CD. These tools could also be freely downloaded from the Andrew Antennas web site at www.andrew.com. For more information on the Andrew “Power Tools” see the Andrew Catalog 38 extract pdf file in this archive.

Gabriel Antenna Data Archive
The source of the legacy Gabriel antenna data contained in this archive is the circa 2003 version 3.0 Gabriel Catalog 990CD. This 3.5 inch format CD-ROM was freely distributed by Gabriel Electronics, Inc. at various microwave radio trade shows during the early 2000s. It contained the Gabriel antenna catalog and antenna pattern data files in NSMA and Adobe .pdf formats. The NSMA antenna data files from the CD-ROM are included in this archive.

Disclaimer: These patterns were publicly available. NSMA is not responsible for their accuracy or content. They are posted as a reference tool for spectrum managers. Contact manufacturers or industry professionals for further guidance as to their accuracy.
