The Authority is mandated to locate all sources of radio frequency interference and

therefore require three (3) specialized, portable and re-deployable direction-finding

equipment capable of detecting emissions from 10 MHz up to 8 GHz. The units must be

designed for both vehicle mounting and tripod/portable deployment so that ICASA teams

can easily operate wherever needed and depending on various requirements/situations.

The operational requirements of the systems shall be designed to allow efficient

removal and installation, facilitating mounting on different vehicles as

operational requirements dictate. Given the operational requirements, deployment

locations may vary; therefore, the system must be capable of being dismantled and

packed into rugged transport cases for shipment to other provincial offices for use or

storage. Most interference incidents reported to the Authority fell within the 10 MHz to

8 GHz range but not limited to.
