FCC Universal Licensing System

Universal Licensing System
The FCC’s Universal Licensing System includes various search features, including callsign and license search.

Congested Area Program
The Congested Area Program is used to identify areas which the FCC has considered to be congested.

Distance Check Program
The Distance Check Program calculates the distance between two entered coordinates by using the criteria found in Rule Section 73.208(c).

US Borders/Regions Program
The US Borders/Regions Program determines the distance to the Canadian and Mexican borders and determines in what region the entered coordinates reside.

FCC Antenna Structure Registration

Antenna Structure Registration Program
The Antenna Structure Registration Program is the process under which each antenna structure that requires FAA notification — including new and existing structures — must be registered with the FCC by its owner.

TOWAIR Program
The TOWAIR Program enables the user to enter and submit key information about their antenna structure in order to determine whether or not registration with the FCC is necessary.

Legacy Antenna Pattern Data Archives

Legacy Radio Frequency Systems (RFS) Antenna Data
In 1999, Cablewave, Celwave, and RFS merge worldwide operations and formed Radio Frequency Systems. RFS designs and manufactures end-to-end RF solutions for wireless and broadcast networks. RFS offers a full range of antennas from 3 GHz to 80 GHz in sizes ranging from 0.4 feet (13 cm) to 15 feet (4.6 meters). Contained within are RFS legacy microwave antenna patterns in a .DAT and .ADF file format.

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.
